303 Stainless Steel Pipe
Product Description
303 stainless steel is an austenitic acid stainless steel containing sulfur and selenium that is easy-cutting and wear-resistant. It is used in situations where easy cutting and high surface finish are required.

It is relatively easy to perform cold and hot processing for 303 stainless steel pipe given its superior plasticity and toughness. It can meet the processing needs of various complex shapes and does not crack. Good toughness and strength in low temperature environments make it suitable for applications that need to go with low temperature environments. Besides, 303 stainless steel pipe can still maintain high strength and good fatigue resistance under high temperatures, and is suitable for structural parts and fasteners in high temperature environments. As a general-purpose stainless steel, 303 stainless steel has a selection of application of uses like the food industry, chemical industry, petroleum, pharmaceutical and other fields to meet various needs.
