Specifications
ASTM A312 TP309H Stainless Steel Tube, is ideal for critical components operating in oxidizing environments at high temperatures, typically up to 1093°C (2000°F). Its high chromium (22-24%) and nickel (11-14%) content provides robust resistance against scaling and thermal fatigue. The controlled higher carbon content (0.04-0.10%) allows TP309H to maintain its structural integrity and resist deformation under sustained heat more effectively, making it an indispensable material in furnace parts, heat exchangers, radiant tubes, and other thermal processing equipment, particularly in power generation and petrochemical industries. Our unwavering commitment to stringent quality control ensures that each ASTM A312 TP309H pipe meets the precise chemical composition and mechanical property requirements of ASTM A312, providing robust and durable solutions for diverse and critical high-temperature projects worldwide.
