ASTM ASME 316H Stainless Steel Pipes & Tubes 0Cr17Ni12Mo2N China Manufacturer

ASTM/ASME 316H Stainless Steel Pipes & Tubes are high-carbon (0.04-0.10%) molybdenum-alloyed austenitic (UNS S31609) products manufactured to ASTM A213/A312 standards, designed for enhanced high-temperature strength and creep resistance while maintaining the superior corrosion resistance of base 316 composition (16-18% Cr, 10-14% Ni, 2-3% Mo). This controlled-carbon variant delivers improved structural stability for pressure-bearing applications in elevated temperature service up to 815°C (1500°F), particularly in petrochemical processing, power generation systems, and industrial furnaces where combined thermal durability and resistance to sulfidation/chloride attack are required, offering approximately 25% higher stress rupture strength than standard 316/L grades for critical high-heat applications.
