Introduction of 430 Stainless Steel
Stainless steel grade 430 is a non-hardenable steel containing straight chromium, belonging to the ferritic group of steels. This steel is 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 usually provided in bar form for use in automatic screw machines. Grade 434 has similar properties as 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 |
Performance Characteristics
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 lower 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 after prolonged heating in the 400-600°C (752-1112°F) range, which can be overcome with annealing.
Heat Treatment
Solution annealing is performed by heating to 815-845°C (1499-1553°F), followed by slow furnace cooling to 600°C (1112°F) and rapid 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-heating at 150-200°C (302-392°F) is required before welding. Post-weld annealing at 790-815°C (1454-1499°F) can address embrittlement in welded metal, though grain refinement will not occur. Recommended filler rods include grade 430, 308L, 309, or 310 based on application requirements.
Machining
Grade 430 stainless steel is easier to machine than standard austenitic steels like grade 304, though galling may occur. Lightly drawn bars are easier to machine than annealed bars. Grade 430F offers excellent machinability.
Fabrication
Grade 430 stainless steel has a low work hardening rate that facilitates easy bending and forming. However, its low ductility rate makes rigorous operations challenging. Grade 430 wire can handle rigorous cold heading, with sub-critical intermediate annealing potentially required for extreme cold working.
Applications of 430 Stainless Steel
- Dish washer linings
- Refrigerator cabinet panels
- Element supports and fasteners
- Stove trim rings and chimney liners
- Automotive trim and lashing wires
