430S stainless steel soft wire

430S is a low-carbon, plain chromium ferritic stainless steel offering reliable corrosion resistance in mildly corrosive environments. This alloy also shows excellent resistance to oxidation at elevated temperatures, making it a popular choice for demanding industrial applications.

Specifications and Forms of 430S Stainless Steel Soft Wire

• Size/Diameter: Ranges from 0.0200 to 0.1870 inches
• Specification: ASTM-A-580
• Temper: Annealed

The alloy is available in versatile forms, including spools, coils, and cut lengths, ensuring flexibility for various uses.

Chemical Composition of 430S Stainless Steel Soft Wire

The typical chemistry of 430S stainless steel soft wire ensures both stability and strength:

• Carbon (C): 0.12 max
• Manganese (Mn): 1.00 max
• Phosphorus (P): 0.04 max
• Sulfur (S): 0.03 max
• Silicon (Si): 1.00 max
• Chromium (Cr): 16.00-18.00

These values are typical and serve as a reference for the alloy’s properties, rather than specific composition requirements.

Key Features of 430S Stainless Steel Soft Wire

With a 17% chromium ferritic stainless steel composition, 430S provides multiple advantages:
