309s Stainless Steel Round Bar

Description

309S is a sulphur containing free-cutting stainless steel suitable for applications where free-cutting and high surface smoothness are the main requirements.
309S stainless steel round bar price in China,309S stainless steel round bar manufacturer.
309S corresponds to the Chinese brand 0Cr23Ni13, American Standard S30908 (AISI, ASTM) features and uses: corrosion resistance, heat resistance are better than 0Cr19Ni9.
309S is a variant of the low carbon 309 stainless steel and is used where welding is required.
The lower carbon content minimises carbide precipitation in the heat affected zone near the weld seam, which in some environments may lead to intergranular corrosion (weld erosion) of the stainless steel.
