Explanation on the uses and properties of stainless steel hot-rolled round bars
201 stainless steel hot-rolled round bar: It is a chromium-nickel-manganese austenitic stainless steel with relatively low magnetism.
202 stainless steel hot-rolled round steel: It is a chromium-nickel-manganese austenitic stainless steel with better performance than 201 stainless steel.
316L stainless steel hot-rolled round steel: 316 stainless steel contains molybdenum and low carbon content. Its resistance to pitting corrosion in marine and chemical industrial environments is much better than that of 304 stainless steel (316L low carbon, 316N nitrogen-containing, high strength, 316F Stainless steel has a high sulfur content and is easy to cut.
304L stainless steel hot-rolled round steel: As a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to that of 304, but after welding or stress relief, its resistance to grain boundary corrosion is excellent. Without heat treatment, It also maintains good corrosion resistance.
304 stainless steel hot-rolled round steel: It 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 phenomenon. Usage: Tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196°C to 700°C)
310 stainless steel hot-rolled round steel: The main features are: high temperature resistance, generally used in boilers and automobile exhaust pipes. Other properties are average.
303 stainless steel hot-rolled round bar: By adding a small amount of sulfur and phosphorus, it is easier to cut than 304, and other properties are similar to 304.
302 stainless steel hot-rolled round steel: 302 stainless steel rods are widely used in auto parts, aviation, aerospace hardware tools, and chemical industry. The details are as follows: handicrafts, bearings, slip patterns, medical instruments, electrical appliances, etc. Characteristics: 302 stainless steel ball is an austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good anti-rust and anti-corrosion properties.
301 Stainless Steel Hot Rolled Round Bar: Good ductility, used for formed products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
