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 various 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 with enhanced 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 comparable to grade 304. 430F, being a high-sulfur free machining grade, has comparatively lower resistance to pitting and crevice corrosion.

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, particularly when heated for extended periods in the 400-600°C (752-1112°F) range, which can be mitigated through annealing.

Heat Treatment

Solution annealing involves heating to 815-845°C (1499-1553°F), slow furnace cooling to 600°C (1112°F), followed by 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 areas, though grain refinement will not occur. Recommended filler rods include grade 430, 308L, 309, or 310 based on application requirements.

Machining & Fabrication

Grade 430 offers better machinability than standard austenitic steels like grade 304, though galling may occur. Lightly drawn bars machine more easily than annealed bars, with grade 430F being particularly easy to machine. The low work hardening rate facilitates easy bending and forming, though low ductility limits rigorous operations. Extreme cold working may require sub-critical intermediate annealing.
