Stainless Steel Pipe
Bestar - Stainless Steel Pipe
ASTM A312 pipe is the general use stainless steel pipe applied in different industries. It covers diameters from 1/8” to 30” and thickness from SCH 10S to SCH 80S. Common use material grades are TP304/304L, TP316/316L. The standard specifications include seamless, straight seam welded and heavily cold welded austenitic stainless steel tubing for high temperature and general corrosive service. There are several grades in this standard, and each steel grade shall confirm to the required chemical composition of C, Mn, P, S, Si, Cr and Cr, Ni, Mo, etc. All the pipes shall be furnished in the heat-treated condition in accordance with the required heat treating temperature and cooling/testing requirements. And also need to comply to the required tensile strength and yield strength.

The ASTM A358 pipe is made with electric fusion welding. The materials for the ASTM A358 have 18% chromium, 8% nickel and manganese, silicon, sulfur, and phosphorus in the composition. The much higher resistant a358 contains molybdenum in the composition. The molybdenum content makes the material resistant to chloride ion corrosion. The A358 is the most used because of its strength and cost efficiency. The astm a358 stainless steel pipe comes in sizes ranging from 8 inches to 72 inches. The thickness of the pipes ranges from 3mm to 60mm. The astm a358 uns s31254 ranges in length up to 6 meters. ASTM A358 Stainless Steel EFW Pipes can come in different finishes such as pickled, BA finish, No 4 finish, and electropolished. The astm a358 has slight mechanical differences.
