Stainless steel plate plasma cutting process
Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.
In recent years, technological progress has significantly improved the quality of plasma cutting of stainless steel plates. These advancements span a range of thicknesses and have reached 6.25 inches.
The early plasma cutting consumes a high current and the cutting speed is also very slow. One of the older systems uses nitrogen as the plasma gas and water injection shield to cut 3 inches of material at 15 inches per minute (IPM) at 750 amps.
So if you want to cut a 5-inch stainless steel plate, you need to use H35 (35% hydrogen, 65% argon) plasma gas and a coaxial flowing water skirt to achieve an amazing 1000 amperes.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits
Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September
According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
