904L stainless steel strip has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride crevice corrosion and stress corrosion cracking, it is extremely resistant to corrosion spots and cracks, the pitting corrosion resistance is slightly better than other steel grades, and it has good machinability and weldability. In pure sulfuric acid in the concentration range of 0~98%, the service temperature of 904L stainless steel strip can be as high as 40 degrees Celsius. It should be noted that in hydrochloric acid, the use of 904L is limited to a lower concentration of 1-2%. In this concentration range, the corrosion resistance of 904L is better than that of conventional stainless steel. It could be produced with different surface and mechanical properties:
Surface: 2B smooth surface, No.1 industrial surface, BA (6k) mirror surface, 8K mirror surface, brushed surface, frosted surface
Soft and hardness (soft material, hard material): deep-drawn soft material; hard material 1/4H, 1/2H, 3/4H, H, EH, SH; HV 30 - 650 degrees.
