201 304 304L 309S 310 310S 316 316L 321 410 430 Grade 25-200mm Diameter Polished/Ba/Mirror Cold Rolled Carbon Steel/Stainless Steel Round Bar

Round steel, square steel, flat steel, hexagonal steel and octagonal steel.
Stainless steel rod according to the production process can be divided into hot rolling, forging and cold drawing three kinds. The specifications of hot rolled stainless steel round steel are 5.5-250 mm. Among them: 5.5-25 mm small stainless steel round steel is mostly supplied in straight strips in bundles, commonly used as steel bars, bolts and various mechanical parts; Stainless steel round steel larger than 25 mm, mainly used for the manufacture of mechanical parts or seamless steel blanks.

Stainless steel rod specification: 1.0MM above 250mm below the size (diameter, side length, thickness or opposite side distance) is not more than 250mm hot rolled and forged stainless steel rod.
According to the composition, it can be divided into Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series) and precipitation hardening series (600 series).
200 series: chromium-manganese-nickel
201,202, etc.: manganese replaces nickel, corrosion resistance is relatively poor, and it is widely used as a cheap substitute for the 300 series in China
300 series: chromium-nickel austenitic stainless steel
304: general model; that is, 18/8 stainless steel. Products such as: corrosion-resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18% chromium plus 8% nickel. It is a non-magnetic stainless steel whose metallographic structure cannot be changed by heat treatment. The GB grade is 06Cr19Ni10.
304 L: Same characteristics as 304, but low carbon, so more corrosion resistant, easy to heat treat, but poor mechanical properties, suitable for welding and products that are not easy to heat treat.
304 N: Same characteristics as 304, a nitrogen-containing stainless steel, nitrogen is added to increase the strength of the steel.
309: Better temperature resistance than 304, up to 980ºC.
309 S: Contains a lot of chromium and nickel, so it has good heat resistance and oxidation resistance. Products such as: heat exchangers, boiler components, and jet engines.
310: Excellent high-temperature oxidation resistance, the highest operating temperature is 1200ºC.
316: After 304, the second most widely used steel grade, mainly used in the food industry, watch accessories, pharmaceutical industry and surgical equipment, adding molybdenum to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery devices. 18/10 grade stainless steel usually meets this application level.
316 L: Low carbon, so more corrosion resistant and easy to heat treat, products such as: chemical processing equipment, nuclear power generators, refrigerant storage tanks.
321: Similar to 304 except that the risk of rusting of the material weld is reduced due to the addition of titanium.
400 series: ferritic and martensitic stainless steel, manganese-free, can replace 304 stainless steel to a certain extent
410: martensitic (high-strength chromium steel), good wear resistance, poor corrosion resistance.
430: ferritic stainless steel, decorative, such as for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
