ASTM A268 TP446-1 stainless steel precision pipe Introduction
ASTM A268 TP446-1 stainless steel precision tube is a high chromium ferritic stainless steel tube with excellent high temperature resistance, oxidation resistance and moderate corrosion resistance, suitable for precision engineering needs in harsh environments.
ASTM A268 TP446-1 High temperature resistant pipe
Advantages of ASTM A268 TP446-1 stainless steel BA tube
ASTM A268 TP446-1 stainless steel cold-rolled tube is a ferritic heat-resistant stainless steel, mainly used in high temperature environments, with long-term temperature resistance of ≤850℃, and better oxidation resistance than 304 stainless steel. It is suitable for high temperature environments such as boiler superheaters and industrial furnace exhaust pipes.
TP446-1 ferritic stainless steel tube size range is 6.35-219 mm in outer diameter, 0.8-20 mm in wall thickness, supports electropolishing (EP, Ra≤0.2μm), and meets the high cleanliness requirements of the food and pharmaceutical industries.
