201 Stainless Steel Bar

Stainless steel Round rod, square steel rod, flat steel bar, hexagonal steel bar, and octagonal steel bar are collectively referred to as stainless steel bars.
Stainless steel rod specifications: Ф Hot-rolled and forged stainless steel bars with dimensions (diameter, edge length, thickness, or distance across edges) not exceeding 250mm and not exceeding 1.0MM and 250mm.
Stainless steel rod materials: 304, 304L, 321, 316, 316L, 310S, 630, 1Cr13, 2Cr13, 3Cr13, 1Cr17Ni2, duplex steel, antibacterial steel, etc
According to composition, it can be divided into Cr system (SUS400), Cr Ni system (SUS300), Cr Mn Ni (SUS200) and Precipitation hardening system (SUS600).
200 Series – Chromium Nickel Manganese Austenitic Stainless Steel
300 Series – Chromium Nickel Austenitic Stainless Steel
301- Good ductility, used for forming products. It can also be hardened by machine speed. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
302- has the same corrosion resistance as 304, but has better strength due to its relatively high carbon content.
303- By adding a small amount of sulfur and phosphorus to make it easier to machine.
304- or 18/8 stainless steel. The GB brand is 06Cr19Ni10.
309- has better temperature resistance compared to 304.
316- The second most widely used steel grade after 304, mainly used in the food industry and surgical equipment, with the addition of molybdenum to obtain a special corrosion-resistant structure. Due to its better resistance to chloride corrosion compared to 304, it is also used as a “marine steel”. SS316 is commonly used in nuclear fuel recovery devices. Grade 18/10 stainless steel usually also meets this application level. [1] Model 321 has similar properties to 304, except that the addition of titanium reduces the risk of material weld corrosion.
400 series – ferritic and Martensitic stainless steel
408- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409- The cheapest model (British and American), usually used for automotive exhaust pipes, is a ferritic stainless steel (chromium steel).
410 Martensite (high-strength chromium steel), with good wear resistance and poor corrosion resistance.
416- The addition of sulfur improved the processing performance of the material.
420- “Cutting tool grade” Martensite steel, similar to Brinell high chromium steel, the earliest stainless steel. It is also used for surgical knife, which can be made very bright.
430 Ferritic stainless steel, for decorative purposes, such as in automotive accessories. Good formability, but poor temperature and corrosion resistance.
440 high-strength cutting tool steel, with slightly higher carbon content, can achieve higher yield strength after appropriate heat treatment, and its hardness can reach 58HRC, making it one of the hardest stainless steels. The most common application example is the “razor blade”. There are three commonly used models: 440A, 440B, 440C, and also 440F (easy to process).
500 series – heat-resistant chromium alloy steel.
600 series – Martensite precipitation hardening stainless steel.
630- The most commonly used precipitation hardened stainless steel model, usually also known as 17-4; 17% Cr, 4% Ni.
Stainless steel rods have broad application prospects and are widely used in industries such as hardware and kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, building decoration, nuclear power, aerospace, military, etc!. Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; Food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Stainless steel bars can be divided into three types according to production processes: hot rolling, forging, and cold drawing. The specifications of hot-rolled stainless steel round steel are 5.5-250mm. Among them: 5.5-25mm small stainless steel round steel is mostly supplied in bundles of straight bars, which are commonly used as reinforcement, bolts and various Machine element; Stainless steel round steel larger than 25mm is mainly used for manufacturing Machine element or seamless steel tube blanks.
