430 Stainless Steel Introduction
Stainless steel grade 430 is a non-hardenable steel containing straight chromium, belonging to the ferritic group of steels. Known for its good corrosion resistance and formability, coupled with practical mechanical properties, it can be used in certain chemical applications.
Grade 430F stainless steel is typically provided in bar form for use in automatic screw machines. Grade 434 has similar properties to grade 430, although it is a molybdenum-bearing version that enhances corrosion resistance.

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, including stainless steel grade 430, have excellent stress corrosion cracking resistance. Grade 430 provides good corrosion resistance to numerous substances, with maximum resistance achieved in well-polished or buffed condition. Its pitting and crevice corrosion resistance is similar to grade 304. 430F is a high-sulfur free machining grade with comparatively lesser resistance to pitting and crevice corrosion than non-free machining grades.
Heat Resistance
Stainless steel grade 430 can resist oxidation up to 870°C (1598°F) in intermittent usage and up to 815°C (1499°F) in continuous usage. It may become brittle at room temperature when heated for extended periods in the 400-600°C (752-1112°F) range, which can be overcome with annealing.
Heat Treatment
Solution annealing involves heating to 815-845°C (1499-1553°F), slow furnace cooling to 600°C (1112°F), followed by quick air-cooling. Slow cooling between 540-400°C (1004-752°F) may cause embrittlement. For sub-critical annealing, heat to 760-815°C (1400-1499°F) followed by air-cooling or water quenching. This stainless steel cannot be hardened by thermal treatment.
Welding
Pre-heat at 150-200°C (302-392°F) before welding. For embrittlement in welded metal, post-weld anneal at 790-815°C (1454-1499°F). Recommended filler rods include grade 430, 308L, 309, or 310 based on application requirements.
Machining
Grade 430 is easier to machine than standard austenitic steels like grade 304, though galling may occur. Lightly drawn bars machine more easily than annealed bars. Grade 430F offers excellent machinability.
Fabrication
Grade 430's low work hardening rate enables easy bending and forming, though low ductility limits rigorous operations. Grade 430 wire handles rigorous cold heading well. Sub-critical intermediate annealing may be required for extreme cold working.
Applications
- Dish washer linings
