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

    Casting

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

  • Hot rolling

    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

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

  • Cold rolling

    Cold rolling

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