SUS409Lis mainly used to manufacture automobile exhaust treatment devices, such as mufflers, exhaust pipes, etc. Due to its excellent corrosion resistance, strength and heat resistance, this stainless steel has broad application prospects in the automotive industry.
SUS409Lcan also be used to manufacture kitchen appliances, water heaters, boilers, etc. This is because corrosion resistance and heat resistance are very important properties in these applications.
SUS409Lalso has good weldability and processability, which makes it ideal for use in industrial manufacturing processes. In short, SUS409L is a stainless steel material with excellent properties, and its wide range of applications include automobile exhaust treatment devices, kitchen appliances, water heaters, boilers, 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.
