Advantages of various materials of stainless steel bars

316L stainless steel bars: 316 stainless steel contains molybdenum and low carbon content, and its pitting corrosion resistance in the ocean and chemical industrial environment is much better than 304 stainless steel! (316L low carbon, 316N high nitrogen strength, 316F stainless steel has a high sulfur content and is easy to cut stainless steel.)
304L stainless steel bars: As a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to 304, but after welding or stress relief, its resistance to intergranular corrosion is excellent, and it can maintain good corrosion resistance without heat treatment.
304 stainless steel bars: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot processing properties such as stamping and bending, and no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196°C-700°C)
310 stainless steel bar: main features: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are general.
303 stainless steel bar: by adding a small amount of sulfur and phosphorus to make it easier to cut than 304, 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. Specific as follows: handicrafts, bearings, sliding flowers, medical instruments, electrical appliances, etc. Features: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but 302 has a higher hardness, HRC≤28, and has good rust and corrosion resistance
301 stainless steel bar: good ductility, used for molded products. It can also be quickly hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
202 stainless steel bar: chromium-nickel-manganese austenitic stainless steel, better performance than 201 stainless steel
201 stainless steel bar: chromium-nickel-manganese austenitic stainless steel, relatively low magnetism
410 stainless steel bar: martensitic (high-strength chromium steel), good wear resistance, poor corrosion resistance.
420 stainless steel bar: “Blade grade” martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. Also used for surgical knives, can be made very bright.
430 stainless steel bar: ferritic stainless steel, decorative, such as for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance
302 stainless steel ball is austenitic steel, close to 304, but 302 has a higher hardness, HRC≤28, and has good rust and corrosion resistance
