ASTM/ASME 429 Stainless Steel Pipes & Tubes are ferritic-grade (UNS S42900) products conforming to ASTM A268 standards, featuring a chromium-rich (14-16%) composition with controlled carbon content (≤0.12%) for improved weldability and formability compared to standard 430 stainless. This cost-effective ferritic alloy offers good resistance to oxidation and sulfur compounds up to 760°C (1400°F), making it particularly suitable for automotive exhaust components, heat exchanger tubing, and furnace parts where thermal cycling resistance and moderate corrosion protection are required. The alloy's ferritic microstructure provides inherent resistance to chloride stress corrosion cracking and demonstrates lower thermal expansion than austenitic grades, while its balanced composition delivers better high-temperature strength than conventional 409 stainless steel for applications demanding enhanced durability in elevated temperature service conditions.
