product description
Stainless steel channel steel [1] is a long steel with a groove-shaped cross section. Same as I-beam, stainless steel channel steel is also divided into ordinary channel steel and light channel steel. The model and specification are also expressed in millimeters of waist height (h) × leg width (b) × waist thickness (d). For example, 120×53×5 channel steel is 120mm waist height, round steel, and a, b, c, etc. must be added to the right of the model to distinguish. Usually, stainless steel channel steel is expressed by the number of centimeters of waist height, such as the upper channel steel is called 12# channel steel. The specification range of channel steel is 5-40#. Including and marking requirements shall be implemented in accordance with GB2101-80.
Stainless steel channel steel
(1) The main purpose of hot-rolled stainless steel ordinary channel steel: ordinary channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and is often used in conjunction with I-beam.
(2) Hot-rolled stainless steel light channel steel (YB164-63) Hot-rolled light channel steel is a kind of steel with wide legs and thin walls, which has better economic effects than ordinary hot-rolled channel steel. Its specifications range from 5-40#. In 1966, the smelting standard specified specifications range from 10-40#. Main application: For construction and steel frame structure.
Commonly used stainless steel channel steel materials for stainless steel production are: 201, 202, 301, 304, 321, 316, 316L, and special materials can generally be customized.
Identification method of stainless steel channel edit
Channel steel number and representation method
①Use international chemical element symbols and national symbols to represent chemical components, and Arabic letters to represent component content:
Such as: China, Russia 12CrNi3A
②Use fixed-digit numbers to represent steel series or numbers; such as: America, Japan, 300 series, 400 series, 200 series;
③The serial number is composed of Latin letters and sequence, which only indicates the purpose.
my country's numbering rules
①Use element symbols
②Purpose, Chinese pinyin, open hearth steel: P, boiling steel: F, killed steel: B, Class A steel: A, T8: special 8,
GCr15: Ball
◆Composite steel, spring steel, such as: 20CrMnTi 60SiMn, (using a few ten thousandths to express the C content)
◆Stainless steel, alloy tool steel (using a few thousandths to express C content), such as: 1Cr18Ni9 one thousandth (that is
0.1%C), stainless C≤0.08% such as 0Cr18Ni9, ultra-low carbon C≤0.03% such as 0Cr17Ni13Mo
International stainless steel marking method
The American Iron and Steel Institute uses three digits to indicate various standard grades of forgeable stainless steel. among them:
①Austenitic stainless steel is marked with 200 and 300 series numbers,
②Ferritic and martensitic stainless steels are represented by 400 series numbers. For example, some of the more common austenitic stainless steels
Are marked with 201, 304, 316 and 310,
③Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C.
Remember, dual phase (austenite-ferrite),
④Stainless steel, precipitation-hardening stainless steel, and high alloys with iron content less than 50% usually use patent names or trademarks.

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

Stainless steel round steel belongs to the category of long products and bars. The so-called stainless steel round steel refers to a long product with a uniform circular cross section
