SUS430 stainless steel grade 430 UNS S43000 chemical composition, standards and properties

SUS430 is a stainless steel under the Japanese JIS standard, and its chemical composition, standards, and properties are similar to those of UNS S43000 (AISI 430) stainless steel under the American ASTM/ASME standard.

1. Chemical composition:
-The main components of SUS430 and UNS S43000/AISI 430 are similar, containing approximately 16% -18% chromium, with small amounts of iron and carbon. The difference is that SUS430 does not contain nickel, while AISI 430 also has a low amount of nickel (usually less than 0.60%).

2. Standard:
-SUS430 complies with JIS G4303 standard, while UNS S43000/ASIS 430 complies with ASTM/ASME standards such as ASTM A240 and ASTM A276.

3. Performance Characteristics:
-Corrosion resistance: SUS430 and UNS S43000/AISI 430 have good corrosion resistance in general environments.
-Magnetism: These two materials are usually ferromagnetic and can be magnetized.
-Processability: It has good machinability, is easy to cut, weld, and form, and is suitable for various manufacturing processes.

In summary, SUS430 and UNS S43000/AISI 430 share similarities in chemical composition, standards, and performance, and can be used interchangeably in many similar application areas. The selection of suitable materials depends on specific needs, standard requirements, as well as supply chain and market factors.
