ASTM A312 TP316H Stainless Steel Seamless Tube Manufacturer

ASTM A312 TP316H is a seamless austenitic stainless steel tube suitable for high-temperature and corrosive environments, such as the chemical, petrochemical, and power generation industries. The "H" indicates a higher carbon content, which improves creep resistance and strength at temperatures above 500°C (932°F).

The 316H stainless steel tubes we supply are a high-carbon version, stabilized with titanium stabilizers to enhance their corrosion resistance. 316H seamless steel tubes have high dimensional accuracy, resulting in high demand. The high carbon content of these tubes improves toughness and reduces corrosion due to increased carbide precipitation during welding.

AISI 316H welded steel tubes have a melting point of 1400°C. They are designed for high-temperature applications and are widely used in the food processing, chemical, and shipbuilding industries.
