    Introduction of stainless steel rod material, application range and quality management
    Material: 304, 304L, 321, 316, 316L, 310S, 630,
    Common materials are 201, 202, 301, 304, 303, 316, 316L, 304L, 321, 2520, 1Cr13, 2Cr13, 3Cr13, duplex steel, antibacterial steel and other materials! The specification is expressed by diameter, such as “50″ which means round steel with a diameter of 50 mm. Round steel is divided into three types: hot rolled, forged and cold drawn. The specification of hot-rolled round steel is 5.5-250 mm.
    Application scope: petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!
    Quality management: ISO9001: 2000 quality management system certification, production license, etc.!
    According to the production process, stainless steel rods can be divided into three types: hot-rolled, forged and cold-drawn. 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 bundles of straight bars, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for the manufacture of mechanical parts or seamless steel pipe billets. .
    According to the composition, it can be divided into Cr series (SUS400), Cr-Ni series (SUS300), Cr-Mn-Ni (SUS200) and precipitation hardening series (SUS600).
    200 series—chromium-nickel-manganese austenitic stainless steel
    300 series—chromium-nickel austenitic stainless steel
    301—Good ductility, used for molded products. It can also be hardened by machine speed. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.
    302—The corrosion resistance is the same as that of 304, because the carbon content is relatively high, the strength is better.
    303—By adding a small amount of sulfur and phosphorus, it can be processed more easily.
    304—namely 18/8 stainless steel. The GB grade is 06Cr19Ni10.
    309—Compared with 304, it has better temperature resistance.
    316—After 304, the second most widely used steel grade, mainly used in food industry and surgical equipment, adding molybdenum element to obtain a special corrosion-resistant structure. Because it has better resistance to chloride corrosion than 304, it is also used as “ship steel”. SS316 is usually used in nuclear fuel recovery devices. 18/10 grade stainless steel usually also meets this application level. [1]
    Model 321—Except for the addition of titanium to reduce the risk of material weld corrosion, other properties are similar to 304.
    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 as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
    410—Martensite (high-strength chromium steel), good wear resistance, poor corrosion resistance.
    416—Sulfur is added to improve the processing performance of the material.
    420—”Cutting tool grade” martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. It is also used for surgical knives, which can be very bright.
    430—Ferritic stainless steel, for decoration, such as car accessories. Good formability, but poor temperature resistance and corrosion resistance.
    440—High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, higher yield strength can be obtained. The hardness can reach 58HRC, which is among the hardest stainless steels. The most common application example is the “razor blade”. There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).
    500 series—heat-resistant chromium alloy steel.
    600 series—Martensitic precipitation hardening stainless steel.
    630—The most commonly used type of precipitation hardening stainless steel, usually called 17-4; 17% Cr, 4% Ni.
