Specifications Material Stainless steel rod specifications: Ф1.0MM less than 250mm size (diameter, side length, thickness, or on the edge distance) is not more than 250mm of hot-rolled and forged stainless steel rods. Stainless steel rod material: 304,304L, 321,316,316L, 310S, 630,1Cr13,2Cr13,3Cr13,1Cr17Ni2, duplex steel, stainless steel and other materials antibacterial bar application prospect, is widely used in metal utensils, shipbuilding, petrochemical , machinery, medicine, food, electricity, energy, construction and decoration, nuclear power, aerospace, military and other industries!. Sea equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; food industry, coastal facilities, ropes, CD rods, bolts and nuts. [Quality Management]: ISO9001:! 2000 quality management system certification, production licenses, etc. Note: You can build all kinds of non-standard materials, specifications of stainless steel bar stainless steel bar presentation materials, applications, quality management [Material]: 304,304L, 321,316,316L, 310S, 630, the common material for 201,202,301,304,303,316,316L, 304L, 321,2520,1Cr13,2Cr13,3Cr13, duplex steel, steel and other antibacterial Material! and so on. Specifications diameter expressed as "50" means that the 50 mm diameter round bar. Round is divided into hot-rolled, cold-forging and drawing three. Hot rolled round steel specifications for the 5.5-250 mm. Applications: oil, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industry quality management:! ISO9001: 2000 quality management system certification, production technology and production licenses] [stainless steel! Stick by the production process can be divided into hot-rolled, cold-forging and drawing three. Hot-rolled stainless steel round bar specifications of 5.5-250 mm. Where: 5.5-25 mm stainless steel round mostly small straight bundles supply, commonly used for steel, bolts and various mechanical parts; greater than 25 mm stainless steel bar, mainly for the manufacture of mechanical parts or seamless steel billet . [Executive standard] stainless steel rod GB: GB / T14975-2002, GB / T14976-2002, GB / T13296-91 American Standard: ASTM A484 / A484M, ASTM A213 / 213A, ASTM A269 / 269M [classification] components can be divided 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 - scalability for molding products. Machine speed can also be hardened. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302 304 with corrosion resistance, due to relatively high carbon intensity and therefore better. 303 - by adding a small amount of sulfur, phosphorus and make it more cutting processing. 304- namely 18/8 stainless steel. GB grades for 06Cr19Ni10. 309 - 304 - better temperature resistance. 316 - After 304, the second most widely used of steel, mainly used in the food industry and surgical equipment, add molybdenum to obtain a special corrosion-resistant structure. Than the 304 because it has better resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 grade stainless steel is usually in line with the application level. [1] Model 321 in addition to the added titanium elements to reduce the risk of material other than the corrosion of the weld performance similar to 304. 400 Series - ferritic and martensitic stainless steel 408 - good heat resistance, low corrosion resistance, 11% Cr, 8% of Ni. 409 - the cheapest model (BAR), commonly used as automobile exhaust pipe, is a ferritic stainless steel (chrome steel). 410 - martensite (high strength chrome steel), good wear resistance, corrosion resistance is poor. 416 add sulfur to improve the processing performance of the material. 420 - "Cutting Class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. Also used in surgical tools, can do very light. 430 ferritic stainless steel, decorative, such as for car accessories. Good shape, but heat resistance and corrosion resistance worse. 440 - high strength cutting tool steel, carbon slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness up to 58HRC, are among the most hard stainless steel. The most common application example is the "razor blades." There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy processing). 500 series - resistant chromium alloy steel. 600 Series - martensitic precipitation hardening stainless steel. 630 - The most common type of precipitation hardening stainless steel models, often called 17-4; 17% Cr, 4% Ni.
