Stainless steel rod material: 304,304L, 321,316,316L, 310S, 630,1Cr13,2Cr13,3Cr13,1Cr17Ni2, dual-phase steel, stainless steel and other materials antibacterial bar application prospects, are 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, nuts. [Quality management]: ISO9001:! 2000 quality management system certification, production license, etc. Note: You can build all kinds of non-standard materials, specifications of stainless steel rod Stainless steel rod material, 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 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 industries Quality management:! ISO9001: 2000 quality management system certification, production licenses [production process] stainless steel! Stick by the production process can be divided into hot-rolled, cold-forging and drawing three. Hot-rolled stainless steel round bar of size 5.5-250 mm. Where: 5.5-25 mm stainless steel round bar is mostly small straight bundles supply, used for reinforcement, 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 bar 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 systems (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- that is 18/8 stainless steel. GB grades for 06Cr19Ni10. 309 - 304 better than temperature resistance. 316 - Following the 304, the second most widely used of steel, mainly for the food industry and surgical equipment, adding Mo to obtain a special corrosion-resistant structure. Better than the 304 because of its 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 - not only because titanium elements to reduce the corrosion of the weld material properties than the risk of a similar 304. 400 Series - ferritic and martensitic stainless steel 408 - good heat resistance, low corrosion resistance, 11% Cr, 8% of Ni. 409 - the cheapest model (England), 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 materials. 420 - "cutting class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. Also used in surgical tools, you 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 common models: 440A, 440B, 440C, in addition 440F (and easy processing). 500 series - heat-resistant chromium alloy steel. 600 Series - martensitic precipitation hardening stainless steel. 630 - The most common type of precipitation hardening stainless steel models, usually called 17-4; 17% Cr, 4% Ni.
