ASTM/ASME 430F Stainless Steel Pipes & Tubes are free-machining ferritic (UNS S43020) products conforming to ASTM A268 standards, featuring a sulfur-enhanced (0.15% min.) chromium (16-18%) composition that combines 430-grade corrosion resistance with superior machinability (90% vs. B1112 steel). This specialty variant maintains the base alloy's oxidation resistance and stress corrosion cracking immunity while achieving exceptional chip-breaking characteristics and surface finish quality (Ra <25 µin) for high-volume production of precision components like fastener fittings, valve seats, and pump components. The sulfur addition facilitates automated machining operations but reduces ductility and weldability compared to standard 430 grade, making it primarily suitable for CNC-turned parts rather than structural applications. Post-machining passivation is recommended to optimize corrosion resistance, particularly for automotive fuel systems, appliance components, and industrial hardware where complex geometries require efficient machining without compromising stainless performance in mildly corrosive environments.
