301 Stainless Steel Pipe Astm

301 Stainless Steel Pipe Astm

1.301 is the most widely used stainless steel, heat-resisting steels.
2.Used in food production equipment, chemical equipment, nuclear energy and so on.

301 (17cr-7ni-Carbon) Material: Compared with 304 steel, Cr, ni content less, cold processing, tensile strength and hardness increased, non-magnetic.

301 Stainless Steel tube is magnetic after cold machining.
