Marine Industry: In the marine industry, S32550 stainless steel is widely used in ship structures, port facilities, marine equipment, and other applications in contact with seawater because of its high corrosion resistance to seawater.
Petroleum and chemical industry:S32550 stainless steelis mainly used to manufacture various pipelines, equipment, etc., to meet transportation and storage needs, while showing excellent corrosion resistance.
Construction industry:S32550 stainless steelhas excellent mechanical properties and weather resistance, and is widely used in building structures, decoration materials, etc.
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:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
