Product Description

ASTM A312 Seamless and Welded Austenitic Stainless Steel Pipe


ASTM A312 / A312M  seamless, straight-seam welded, and cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. Several grades of steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, titanium, columbium, tantalum, nitrogen, vanadium, copper, cerium, boron, aluminum, and others. All pipes shall be furnished in the heat-treated condition in accordance with the required heat treating temperature and cooling/testing requirements. Tensile properties of the material shall conform to the prescribed tensile strength and yield strength. The steel pipe shall undergo mechanical tests such as transverse or longitudinal tension test and flattening test. Grain size determination and weld decay tests shall be performed. Each pipe shall also be subjected to the nondestructive electric test or the hydrostatic test.
 

ASTM A 312   Stainless Tube Manufacturer

We are professional ASTM A 312   stainless tube manufacture & supplier, having capability to produce wide range size steel tube for heat exchanger system, manufacturing process starts from extrusion of billet, by cold rolling and cold drawn methods to control size and tolerance, heat treatment will be finished after cold working to achieve original steel properties, which improve high temperature resistance and corrosion resistance, then tubes should be under pickling passivation condition.
