ASTM A268 TP446-2 high chromium ferritic stainless steel pipe is an economical alternative to 310S austenitic stainless steel, suitable for high temperature flue gas, sulfur/chlorine containing industrial environment and precision structural parts.
ASTM A268 TP446-2 High temperature resistant pipe
Advantages of ASTM A268 TP446-2 steel tube
ASTM A268 TP446-2 stainless steel round tube follows the ASTM A268 standard and is a ferritic heat-resistant stainless steel. Its chemical composition mainly includes chromium (Cr), nickel (Ni) and other alloy elements, and has good high temperature resistance and mechanical properties.
TP446-2 stainless steel square tube can withstand high temperatures up to 1150℃, and its oxidation resistance is better than 304/310S stainless steel. It is suitable for industrial furnace exhaust pipes and incinerator pipes (resistant to high temperature sulfur oxidation).
