1.309s stainless steel grade
corresponding 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).
2.309S Speciality
It can withstand repeated heating under 980 ℃, has higher strength and oxidation resistance, high temperature carburizing performance.
