Possible Alternative Grades

Grade

Reasons for choosing 430

430F

Higher machinability than 430 is needed in bar product, and reduced corrosion resistance is acceptable

434

Better pitting resistance is required

304

Slightly higher corrosion resistance is needed, together with greatly improved ability to be welded and cold formed

316

Much better corrosion resistance is needed, coupled with greatly improved ability to be welded and cold formed

3CR12

Lower corrosion resistance is acceptable in a cost-critical application

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. 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. 

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.

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 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.

Welding

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. 

Machining

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.

Fabrication

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. 

Applications of 430 Stainless Steel

The following are the applications for stainless steel grade 430:

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