ASTM A268 Seamless TP405 1.4002 Ferritic Martensitic Steel Tubes
YUHONG Group offers ASTM A268 TP405 SMLS/WELDED ferritic martensitic stainless steel tubes and we sell these tubes in more than 70 countries up to now. This specification covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service.
TP405 ferritic martensitic steel is a low carbon, 12% chrome steel, not subject to appreciable hardening through air cooling from high temperatures. This tendency retards the formation of hardening cracks caused by welding. And practically with the same corrosion and oxidation resistance as TP410. Besides, this material can be machined, drawn, spun and formed without difficulty.
