Product Description
Stainless steel rod material, application range, introduction to quality management
Material: 304, 304L, 321, 316, 316L, 310S, 630,
Common materials are 201, 202, 301, 304, 303, 316, 316L, 304L, 321, 2520, 1Cr13, 2Cr13, 3Cr13, dual-phase steel, antibacterial steel and other materials! Specifications are expressed in diameter, such as "50", which means round steel with a diameter of 50 mm. Round steel is divided into three types: hot rolled, forged and cold drawn. The size of hot rolled round bar is 5.5-250 mm.
Application range: petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!

Advantages of stainless steel bar:
1. Wide Specifications Range;
2. Pure steel chemical composition;
3. Outstanding mechanical properties;
4. Good performance after welding;
5. Good shape and high precision;
6. Excellent corrosion-resistant and long service life.
Production Process
According to the production process, stainless steel bars can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets
