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. Its pitting and crevice corrosion resistance are 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.

430 Stainless Steel Heat Resistance

It 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 tends to become brittle, especially when it has been heated for a long time in the 400-600°C (752-1112°F) range.

Heat Treatment

Solution annealing can be performed by heating to 815 – 845°C (1499-1553°F). Then it has to be slow furnace cooled to 600°C (1112°F) and quickly followed by air-cooling – 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.

Welding

To perform any welding, It has to be pre-heated at 150-200°C (302-392°F).

Machining

The machinability of the stainless steel 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.

430 Stainless Steel Fabrication

The low ductility rate, however, makes it difficult to perform very rigorous operations.

430 Stainless Steel Applications

• Dishwasher linings
• Refrigerator cabinet panels
• Element supports and fasteners
• Stove trim rings and chimney liners
• Automotive trim and lashing wires

The following sections will provide the key properties of grade 430 coil, sheet and plate – covered under ASTM A240/A240M.
