Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels.

Corrosion Resistance:

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.

Heat Resistance:

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.
