Exhaust pipe, tube, heat treatment furnace, heat exchangers, incinerator for heat resistant steel, high temperature/high temperature contact parts. 310S is heat resistant steel as an important material in aerospace, chemical industry, widely used in high temperature environmentCorresponding brand in China is 06Cr23Ni13; Amercia Standard S30908, AISI, ASTM; JIS G4305 standard sus; European standard 1.4833. 309s is containing sulfur free cutting stainless steel, used for main free cutting and the bright/clean surface demanding occasions. 309 s is low carbon content variations of 309 stainless steel, welding is applied to the occasion. Low carbon content is made in the heat affected zone near the weld in the precipitation of carbide to a minimum, and may result in precipitation of carbide stainless steel intergranular corrosion in some environments (welding erosion).It can withstand repeated heating under 980 ℃, has higher strength and oxidation resistance, high temperature carburizing performance.

  1) Yield strength/MPa:≥ 205

  2) Tensile Strength/MPa:≥515

  3) Elongation/%:≥ 40

  4) Reduction Of Area/%:≥50

309s is furnace-using materials. 309s is widely used in boilers, energy (nuclear power, thermal power, fuel cell), industrial furnaces, incinerator, heating furnace, chemical, petrochemical and other important areas.
