430 Stainless Steel

430 Stainless Steel

430 stainless steel is a ferritic stainless steel with excellent corrosion resistance and mechanical properties. Therefore, it can resist most common corrosive media, including water, air, acid and alkali solutions, etc. It has good strength and hardness and can withstand certain mechanical loads and impacts.

One of the advantages of 430 stainless steel is that its price is relatively low and it is a cost-effective stainless steel material. It is widely used in building materials, kitchen appliances, automobile exhaust systems, electronic equipment and other fields.

What‘s The Feature Of 430 Stainless Steel?

All ferritic grades, such as stainless steel grade 430, have excellent stress corrosion cracking resistance. Grade 430 has good corrosion resistance to numerous substances, such as certain organic acids and nitric acid. The corrosion resistance is maximized in well-polished or buffed condition. Its pitting and crevice corrosion resistance is quite similar to that of grade 304. 430F is a high-sulfur free machining grade, and therefore the resistance to pitting and crevice corrosion is comparatively lesser than those grades that are non-free machining.

Stainless steel grade 430 is capable of resisting oxidation up to 870°C (1598°F) in intermittent usage, and up to 815°C (1499°F) in continuous usage. At room temperature, it has the tendency to become brittle, especially when it has been heated for a long time in the 400-600°C (752-1112°F) range. This issue can be overcome with annealing.

Solution annealing can be performed by heating stainless steel grade 430 to 815 – 845°C (1499-1553°F). Then it has to be slow furnace cooled to 600°C (1112°F) and followed by air-cooling in a quick manner – as slow cooling between 540 and 400°C (1004 and 752°F) tends to cause embrittlement.

For sub-critical annealing, heating should be performed to 760-815°C (1400-1499°F), followed by air-cooling or water quenching.

This stainless steel cannot be hardened by thermal treatment.

To perform any welding, stainless steel grade 430 has to be pre-heated at 150-200°C (302-392°F). In case of embrittlement in the welded metal, the particular area can be post-weld annealed at 790-815°C (1454-1499°F); however grain refinement will not happen.

It is recommended that grade 430, 308L, 309 or 310 filler rod should be used based on the application.

The machinability of stainless steel grade 430 is a lot easier than standard austenitic steels such as grade 304 – but there is a chance for galling. Lightly drawn bars are easier to machine than bars in the annealed condition. Grade 430F is easy to machine.

Stainless steel grade 430 has a low work hardening rate which enables easy bending and forming. The low ductility rate, however, makes it difficult to perform very rigorous operations. It is possible for grade 430 wire to handle rigorous cold heading. Sub-critical intermediate annealing may be required for extreme cold working.
