Stainless Steel Pipe Tube A312/ A312M TP309S S30908 Used in furnace material
Introduction to products:
The corresponding Chinese brand of 309S is 0Cr23Ni13, and the American standard S30908 (American AISI, ASTM) characteristics and uses: corrosion resistance and heat resistance are better than 0Cr19Ni9.
The 309s is a variant of the lower carbon 309 stainless steel for use where welding is required. The lower carbon content minimizes the carbides precipitated in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.
APPLICATIONS :
Use: furnace material.
Widely used in boilers, energy (nuclear power, thermal power, fuel cell), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.
