Product Description
Stainless steel bars are hot rolled or forged from stainless steel ingots.
The production of stainless steel bars emerged with the development of stainless steel. Due to the increasingly wide range of applications of stainless steel bars, such as the foundation of high-rise buildings in cold areas, isolation nets beside highways, household items, etc., the hot-rolled production of stainless steel bars has been greatly developed. 30% of stainless steel products in my country %, foreign countries only account for 8%-10%. With the rapid development of cutting-edge technologies such as petroleum, chemical industry, energy and atomic energy, aerospace, and marine development, higher comprehensive performance requirements have been put forward for stainless steel, which not only requires good corrosion resistance, but also requires high strength, high temperature and high pressure resistance. , radiation resistance, low temperature resistance and other properties, so that the types of stainless steel have been further developed.

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.
316L stainless steel bar: 316 stainless steel contains molybdenum and low carbon content, and its resistance to pitting corrosion in marine and chemical industrial environments is much better than 304 stainless steel! (316L low carbon, 316N nitrogen high strength and high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel.
304L stainless steel bar: As a low-carbon 304 steel, in general, the corrosion resistance is similar to 304, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent, and it can also be used without heat treatment. Maintain good corrosion resistance.
304 stainless steel bar: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700°C).
310 stainless steel bar: The main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are general.
303 stainless steel bar: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus, and other properties are similar to 304.
302 stainless steel bar: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. Specifically as follows: handicrafts, bearings, slippery, medical equipment, electrical appliances, etc. Features: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance.
301 stainless steel bar: good ductility, used for forming products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance.
