430 Stainless Steel Chemical Composition
430 stainless steel has high chromium but very low nickel content.
Chromium content is between 16 and 18%, while nickel content is
0.5% max. Its other constituents are present in trace amounts.
There’s a maximum of 1% each of manganese and silicon, 0.12%
carbon, and 0.03% and 0.04% respectively for sulfur and
phosphorous. As before, the balance is made up of iron, around 80%.

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. The corrosion resistance is
maximized in well-polished or buffed conditions. Its pitting and
crevice corrosion resistance is quite similar to that of grade 304.
430F is a high-sulphur-free machining grade, and therefore the
resistance to pitting and crevice corrosion is comparatively lesser
than those grades that are non-free machining.
Welding
To perform any welding, stainless steel grade 430 has to be
pre-heated at 150-200°C (302-392°F). In the 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 ductility of the welded products can be improved by annealing
post-welding at temperatures of 760 to 815°C. However, this is not
required for thin welded products. Welding of exhaust tubing of
automobiles is carried out without filler rods.
Heat Treatment
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
quickly – 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.
430 Stainless Steel Applications
This grade of stainless steel can be supplied in all the usual
forms: sheet, strip, plate, bar and tube. Its low cost combined
with good corrosion resistance lends itself well to the making of
domestic appliances. A lot of 430 stainless is used in cookers,
washing machines, and dishwashers. Stove element supports are often
produced in 430 stainless steel. It can also be found in shallow
draw/limited-depth Stainless Steel sinks.
The motor industry uses a lot of 430 stainless steel in its
automotive trim and muffler systems. You will also find it used for
flue linings, industrial roofing, wall cladding, hinges, and
fasteners.
