Product Description
303 stainless steel bar is made of an austenitic, easy-cutting, wear-resistant acid stainless steel containing sulfur and selenium respectively. It is used in situations where cutting and high surface finish are needed. 303 stainless steel bars are easy to perform cold and hot processing owing to good plasticity and toughness. They do not easily crack during processing and can meet the processing needs of complex shapes. Such bars can still maintain good toughness and strength in low temperature environments and is suitable for applications that need to deal with low temperature environments. Besides, 303 stainless steel bars can still maintain high strength and good fatigue resistance at high temperatures. As a general-purpose stainless steel type, 303 stainless steel bars can apply to a wide range of things. They are a common manufacturing part in the food industry, chemical industry, petroleum, pharmaceutical and other fields to meet different needs.
