Application Scenario

200J1 stainless steel pipe: The carbon content is slightly higher than that of 200J4 stainless steel, and the copper content is lower than J4. Its processing performance is not as good as J4 stainless steel material. 200J1 stainless steel pipe is suitable for ordinary shallow deep drawing and large angle deep drawing products such as decorative panels, bathroom products, sinks, and product pipes.

200J2, J5 stainless steel pipe:mostly used for decorative pipes, easy to process, high hardness (both above 96°), beautiful polishing, but easy to burst when used in bent pipes (90°). In terms of flat panels, due to their high hardness, the panel surface is more beautiful and can be treated with frosting, polishing, color plating and other surface treatments. But the biggest problem is bending. It is easy to break when bending and burst when stretched, so the ductility is not good.

Production Process

The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:

Casting

Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
Hot rolling

During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing

Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling

Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
