SS 201 Pipes is an austenitic nickel-chromium-maganese stainless steel which developed originally to conserve Nickel. Stainless201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304. Nickel is replaced by additions of manganese and nitrogen.Stainless Grade 201 is non-hardenable by thermal treatment, but may be cold worked to high tensile strengths. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked.
201 seamless pipes are manufactured following the guidelines and requirements set forth in the ASME,ASTM and API standard. 201 round seamless pipes are produced without any welded joints, ensuring a continuous and seamless structure. It is also easy to weld, and its surface can be easily finished to achieve a polished or matte look.
2B finish refers to the surface finish of stainless steel, indicating a smooth, matte appearance with a slight reflectivity. It is achieved by cold-rolling the stainless steel sheet or coil and then annealing it in a controlled atmosphere.
Steel Pipes SS201 with 2B finish would typically have a round cross-section and a smooth, matte surface. It is made from stainless steel grade 201, which is a low-cost austenitic stainless steel with good corrosion resistance and formability. As one of the stainless steel tube manufacturers and suppliers, we stock and sell good quality steel pipe grade 201 as per ASTM A213 AND A249, JBL STEEL is always all your side.
