ОЦЕНКА
Оценка 430 нержавеющая сталь (UNS S43000, В 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, и формуемость, 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, и 304, can be used in certain chemical applications.
PROPERTIES
- Хорошая устойчивость к коррозии и окислению
- Can be readily fabricated by cold working
- Отличная формуемость
- Low costs

| 2Б (Mill Finish) |
Яркий, cold-rolled finish resulting in the same manner as 2D finish, except that the annealed and descaled sheet received a final light roll pass through polished rolls. This is the general-purpose cold-rolled finish that can be used, or a preliminary step to polishing. | |||||
