316 stainless steel round bar is the grade of American standard. For the Chinese standard, it is 0Cr17Ni12Mo2. 316 stainless steel rod is a better stainless steel than 304. In seawater and other media, the corrosion resistance is better than 0Cr19Ni9. It is mainly pitting corrosion resistant material.
Summary: Add Mo (2~3%), excellent pitting corrosion resistance, excellent high temperature creep strength.2. Features: 1. The appearance of cold-rolled products is good and beautiful; 2. Add Mo, excellent corrosion resistance, especially pitting resistance; 3. Excellent high temperature strength; 4. Excellent work hardening (weak after processing Magnetic) 5. Non-magnetic in solid solution state; 6. Compared with 304 stainless steel, the price is higher. Scope of application: pipes, heat exchangers, food industry, chemical industry, etc.
316 stainless steel round bar: 316 stainless steel round bar contains molybdenum and low carbon content, and its resistance to pitting corrosion in marine and chemical industry environments is much better than that of 304 stainless steel! (316L low-carbon, 316N nitrogen-containing high-strength, 316 stainless steel round bar with high sulfur content, easy to cut stainless steel).
304L stainless steel round bar: As a low-carbon 304 steel, in general, its corrosion resistance is similar to that of 316L, but after welding or stress relief, its resistance to intergranular corrosion is excellent, and it can also be used without heat treatment. Maintain good corrosion resistance.
316 stainless steel rod: 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. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (operating temperature -196°C-700°C).
310 stainless steel round bar: the main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are general.
310S stainless steel round bar: It is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, 310S has much better creep strength and can continue to work at high temperatures. Good high temperature resistance.
303 stainless steel round bar: by adding a small amount of sulfur and phosphorus, it is easier to cut than 304, and its other properties are similar to 304.
302 stainless steel rod: 302 stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: handicrafts, bearings, sliding flowers, medical instruments, electrical appliances, etc.
301 stainless steel round 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.
202 stainless steel round bar: It belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel.
201 stainless steel round bar: It belongs to chromium-nickel-manganese austenitic stainless steel with relatively low magnetic properties.
410 stainless steel round bar: It belongs to martensite (high-strength chromium steel), has good wear resistance and poor corrosion resistance.
420 stainless steel round bar: "cutting tool grade" martensitic steel, similar to the earliest stainless steel of Brinell high chromium steel. It is also used for surgical knives and can be made very shiny.
317 stainless steel round bar: the pitting resistance is better than 316 steel. Used for printing and dyeing equipment materials.
430 stainless steel round bar: ferritic stainless steel, for decoration, such as for car accessories. Good formability, but poor temperature resistance and corrosion resistance.
302 stainless steel round bar belongs to 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.
