Stainless steel square bar is a steel material with good corrosion resistance, heat resistance, low temperature strength and mechanical properties.
Stainless steel square bars are a critical component in the manufacturing and engineering sector, due to the versatility of the material. Typical uses include the fabrication of framework, support, axles, and braces as well as in markets such as medical, oil and gas, construction and architectural. Our bars are high quality, are easy to cut and offer superior workability and machinability. Stainless steel alloys offer excellent corrosion resistance, and our bar products are no exception.
The process flow of the Stainless Steel Square Bar production line: billet acceptance → heating → rolling → double scale cutting → cooling → cutting → inspection → packaging → measurement → warehousing.
