-Detailed explanation of 300 series stainless steel round rods:
316L stainless steel round rod: 316 stainless steel contains molybdenum and low carbon content. Its resistance to pitting corrosion in the ocean and chemical industrial environment is much better than that of 304 stainless steel! (316L is low carbon, 316N is nitrogen-containing and has high strength, 316F stainless steel has high sulfur content and is easy to cut stainless steel.
304L stainless steel round bar: As a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to that of 304. However, after welding or stress relief, its resistance to grain boundary corrosion is excellent. It can also resist corrosion without heat treatment. Maintain good corrosion resistance.
304 stainless steel round bar: 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-700°C) 310 stainless steel round rod: main features are: high temperature resistance, generally used in boilers and automobile exhaust Pipe. Other properties are average.
303 stainless steel 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 round rod: 302 stainless steel rod is 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 round rod: good ductility, used for molded products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
-Detailed explanation of 200 series stainless steel round rods:
202 stainless steel round rod: It is a chromium-nickel-manganese austenitic stainless steel with better performance than 201 stainless steel.
201 stainless steel round rod: belongs to chromium-nickel-manganese austenitic stainless steel with relatively low magnetism. Detailed explanation of 400 series stainless steel round rod:
410 stainless steel round rod: belongs to martensitic (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 such as Brinell high chromium steel. Also used in surgical knives, which can be made very shiny.
430 stainless steel round rod: ferritic stainless steel, used for decoration, such as car accessories. Good formability, but poor temperature resistance and corrosion resistance.
-National standard for stainless steel rods: GB/T14975-2002, GB/T14976-2002, GB/T13296-91
American standards: ASTM A484/A484M, ASTM A213/213A, ASTM A269/269M
Stainless steel rods can be divided into three types according to production technology: hot rolling, forging and cold drawing. The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in straight strips and are commonly used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used to manufacture mechanical parts or seamless steel pipe blanks.
