Austenitic SS Pipe/Tube

austenitic ss pipe/tube main grades: 304/L/H/LN, 316/L/H/LN/Ti/LMod, 310S/H, 317/L, 321/H, 347H/HFG

austenitic ss pipe/tube has austenite as its primary phase at both elevated and room temperature. A stable austenite structured steel contains about 18% Cr, 8% ~ 10% Ni and about 0.1% C. Chrome-nickel austenitic stainless steel including the most familiar stainless steel 18Cr-8Ni (TP304) and the series of high Cr-Ni steel developed by increase Cr, Ni contents and add Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is characterized by non-magnetic, high plasticity and ductility but lower strength. It can be only strengthened via cold working (by adding S, Ca, Se, Te and etc, austenitic stainless steel can have excellent machinability). Grades: 304/L/H/LN, 316/L/H/LN/Ti/LMod, 310S/H, 317/L, 321/H, 347H/HFG
