Physical characteristics and applicationsedit
1. Corrosion resistance
The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316L stainless steel is also resistant to the erosion of the ocean and corrosive industrial atmosphere.
2. Heat resistance
In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316L stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to continuously act on 316L stainless steel, but when 316L stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and the above temperature range can be used.
3. Heat treatment
Solution annealing is carried out in the temperature range of 1010-1150 degrees, and then rapidly cooled. 316L stainless steel cannot be hardened by heat treatment.
welding
316L stainless steel has good welding performance. All standard welding methods can be used for welding. During welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used according to the application. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post-weld annealing treatment is not required.
4. Typical use
Pulp and paper equipment, heat exchangers, dyeing equipment, film washing equipment, pipelines, materials for exterior buildings in coastal areas, and bracelets and cases of high-end watches. [1]
Stainless steel angle steel
1. Types and specifications
It is mainly divided into two types: equilateral stainless steel angle steel and unequal side stainless steel angle steel. Among them, unequal side stainless steel angle steel can be divided into unequal side thickness and unequal side thickness.
The specifications of stainless steel angle steel are expressed by the dimensions of side length and side thickness. The specifications of domestic stainless steel angle steel are 2-20, and the number of centimeters on the side length is the number. The stainless steel angle steel of the same number often has 2-7 different side thicknesses. Imported stainless steel angles indicate the actual size and thickness of both sides and indicate the relevant standards. Generally, those with a side length of 12.5cm or more are large stainless steel angles, those with a side length between 12.5cm and 5cm are medium-sized stainless steel angles, and those with a side length of less than 5cm are small stainless steel angles.
2. Import and export situation
my country imports and exports stainless steel angle steel in certain batches, mainly from Japan and Western Europe. Exports to regions are mainly Hong Kong, Macau, Southeast Asia, Latin America and Arab countries. Export production companies are mainly steel mills (rolling mills) in Jiangsu, Liaoning, Hebei, Beijing, Shanghai, Tianjin and other provinces and cities.
The imported stainless steel angles are mostly large and small stainless steel angles and special-shaped stainless steel angles. The export varieties are mostly medium-sized stainless steel angles such as No. 6 and No. 7.
3. Appearance quality requirements
The surface quality of stainless steel angle steel is stipulated in the standard. Generally, it is required that there should be no harmful defects in use, such as delamination, scarring, and cracks.
The allowable range of geometric shape deviation of stainless steel angle steel is also specified in the standard, which generally includes items such as curvature, side width, side thickness, top angle, theoretical weight, etc., and stipulates that the stainless steel angle steel must not be significantly twisted.
4. Chemical composition inspection
(1) Composition index: The chemical composition of stainless steel angle steel belongs to the rolled steel series for general structural use. The main inspection indexes are C, Mn, P, and S. According to different grades, the content varies. The approximate range is C<0.22%, Mn: 0.30—0.65%, P<0.060%, S<0.060%.
(2) Inspection methods: When testing the above chemical components, the commonly used standard inspection methods include GB223, JISG1211-1215, BS1837, BS Manual 19, GOST 22536, etc.
5. Commonly used products, specifications and standards
GB/T2101-89 (General provisions for section steel acceptance, packaging, marking and quality certificate); GB9787

Steel Sheet pile Description The steel sheet pile is a kind of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and compact steel structure with a retaining wall or a water retaining wall. The steel sheet pile is a type of steel with a lock. Its cross-sections are straight, trough and Z-shaped. There are various sizes and interlocking forms. The common ones are Larsonian, Lakwanaian and so on. Its advantages are: high strength, easy to penetrate hard soil; can be constructed in deep water, if necessary, add diagonal support to become a cage. It has good waterproof performance; it can be formed into cofferdams of various shapes as required and can be reused many times. Therefore, it has a wide range of uses. classification Steel sheet pile products are classified into cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles according to the production process. (1) There are two types of cold-formed steel sheet piles: non-bite type cold-formed steel sheet piles (also called channel plates) and bite type cold-formed steel sheet piles (divided into L-shaped, S-shaped, U-shaped, and Z-shaped) . Production process: Use thinner plates (commonly used thickness 8mm ~ 14mm) to be continuously rolled and formed in the cold bending unit. Advantages: less investment in the production line, lower production cost, flexible control of product size. Disadvantages: the thickness of each part of the pile body is the same, the section size cannot be optimized, which leads to an increase in steel consumption, the shape of the lock part is difficult to control, the joint is not tightly buckled, and the water cannot be stopped, and the pile body is easy to tear during use. (2) Hot-rolled steel sheet piles Hot-rolled steel sheet piles in the world mainly include U-shaped, Z-shaped, AS-shaped, H-shaped and dozens of specifications. The production, processing and installation processes of Z-type and AS-type steel sheet piles are relatively complicated, and are mainly used in Europe and America; U-type steel sheet piles are mainly used in China. Production process: It is formed by high temperature rolling by a section steel rolling mill. Advantages: standard size, superior performance, reasonable cross-section, high quality, and tight water barrier for the lock bite. Disadvantages: technical difficulty is relatively high, production cost is relatively high, specification series are not flexible. In engineering construction, the application range of cold-formed steel sheet piles is relatively narrow, and most of them are used as supplementary materials for applications. Hot-rolled steel sheet piles have always been the leading product for engineering applications. Based on the many advantages of steel sheet piles in construction operations, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Management Committee issued the national standard for "Hot Rolled U-shaped Steel Sheet Pile" on May 14, 2007, and on December 1, 2007 Formally implemented. At the end of the 20th century, Maanshan Iron & Steel Co., Ltd. produced more than 5,000 tons of U-shaped steel sheet piles with a width of 400mm with the introduction of the universal rolling mill production line from abroad. The U-shaped steel sheet piles were successfully used in the cofferdam of Nenjiang Bridge and the 300,000 tons of Jingjiang New Century Shipyard. Ton shipyard and Bangladesh flood control projects. However, due to the low production efficiency, poor economic efficiency, low domestic demand and insufficient technical experience during the trial production period, continuous production was not possible. According to statistics, the annual consumption of steel sheet piles in my country remains at about 30,000 tons, accounting for only 1% of the world’s total, and it is limited to permanent projects such as the construction of some ports, wharves, and shipyards, as well as the construction of bridges, cofferdams, and foundation pit support Temporary works. The cold-formed steel sheet pile is continuously rolled and formed by the cold-formed unit, and the side lock can be continuously overlapped to form a steel structure of the sheet pile wall. The cold-formed steel sheet pile is made of thinner plates (commonly used thickness is 8mm-14mm) and processed by cold-formed forming units. The production cost is lower and the price is cheap, and the fixed-length control is more flexible. However, due to the simple processing method, the thickness of each part of the pile body is the same, the cross-sectional size cannot be optimized, which leads to an increase in steel consumption; the shape of the lock part is difficult to control, the joint is not tightly buckled, and the water cannot be stopped; limited by the capacity of cold bending processing equipment, It can produce low-strength ste
