CẤP
Cấp 430 thép không gỉ (UNS S43000, TRONG 1.4016) is the most widely used family of Ferritic alloys. It’s also one of the widely used “non-hardenable” stainless with good physical and mechanical characteristics, about three-quarters the ductility of low carbon strip and inferior to chrome-nickel grades; cost less than chromium-nickel stainless steels. It is known for its good corrosion resistance to numerous substances, excellent stress, và khả năng định hình, coupled with practical mechanical properties.
430 stainless steel is magnetic stainless steel in the annealed condition. It can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes.
The steel has limited weldability and should not be used in the as-welded condition for dynamic or impact loaded structures. It has excellent resistance to citric and nitric acid, sulfur gases; slightly less corrosion and heat resistance than grade 301, 302, Và 304, can be used in certain chemical applications.
PROPERTIES
- Chống ăn mòn và oxy hóa tốt
- Can be readily fabricated by cold working
- Khả năng định hình tuyệt vời
- Low costs
- từ tính
