316L stainless steel bar: 316 stainless steel containing molybdenum and low carbon content, and chemical industries in the marine environment in the point of corrosion resistance substantially better than the 304! (316L low-carbon, 316N high strength and high nitrogen, 316F higher sulfur content stainless steel, free cutting steel. 
 304L stainless steel bar: 304 as a low-carbon steel, in general, corrosion resistance and 304 similar, but after welding or eliminate stress, its excellent corrosion resistance to grain boundary, in the case without heat treatment, but also good corrosion resistance. 
 304 Stainless steel bar: good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping, bending and other thermal processing is good, no hardening heat treatment. Usage: tableware, kitchen cabinets, boilers, auto parts, medical equipment, building materials, food industry (temperature -196 ° C-700 ° C). 
 310 Stainless steel bar: The main features are: high temperature, general use of the boiler, automobile exhaust pipes of other properties in general. 
 303 Stainless steel bar: by adding a small amount of sulfur and phosphorus to more than 304 cutting, and 304 with other similar properties. 
 302 Stainless steel bar: 302 stainless steel rods are widely used in auto parts, aviation, aerospace hardware tools, chemical industry. As follows: crafts, bearings, sliding flowers, medical equipment, electrical appliances. Features: 302 stainless steel is austenitic steel ball, and closer to 304, but 302 higher hardness, HRC ≤ 28, with a good rust and corrosion. 
 301 Stainless steel bar: ductile, for formed products. It can also be machined quickly hardening. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 
 302 austenitic stainless steel ball is, and closer to 304, but 302 higher hardness, HRC ≤ 28, with a good rust and corrosion. 

 410 Stainless steel bar: is martensite (high-strength chromium steel), wear resistance, corrosion resistance is poor. 
 420 Stainless steel bar: "cutting class" martensitic steel, high chrome steel Brinell like this first stainless steel. Also used in surgical tools, can be made very light. 
 430 Stainless steel bar: ferritic stainless steel, decorative, such as for automotive accessories. Good formability, but the temperature resistance and corrosion resistance worse. 
 Stainless Steel Products Co., the company adhere to "good faith cooperation, mutual benefit and win-win" for the purpose of a professional focus on the spirit, speech power to create first-class products and corporate image.
