309s Stainless steel bar

    309s is a free cutting stainless steel with sulfur, used in applications where free cutting and high surface smoothness are the main requirements.
309s Stainless steelround bar Price in China ,Manufacturer of 309s Stainless Steelround bar .
309s corresponding to the Chinese brand is 0Cr23Ni13, the American standard S30908 (AISI, ASTM) characteristics and use: corrosion resistance, heat resistance are better than 0Cr19Ni9.
     The 309s is a variant of the lower carbon 309 stainless steel for use where soldering is required.
     The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments

   Stainless steel bars are hot rolled or forged from stainless steel ingots.Round steel, square steel, flat steel, hexagonal steel and octagonal steel are collectively referred to as stainless steel bar. Stainless steel rods are solid and cylindrical. They have broad application prospects and are widely used in hardware kitchenware, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, construction and decoration, nuclear power, aerospace, military and other industries. 304L contains less carbon than 304 and is more resistant to corrosion. After welding or stress relief, its resistance to grain boundary corrosion is excellent; in the case of no heat treatment, it can also maintain good corrosion resistance, and the operating temperature is -196 ° C ~ 800 ° C. It is used in field open-air machines in chemical, coal and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts of building materials and parts with difficult heat treatment.
