17-4HP stainless steel rod professional \ Production \ sales \: various domestic - imported stainless steel plate, stainless steel, stainless steel pipe, stainless steel bar, stainless steel wire, stainless steel angle, stainless steel channel and so on. Main Material: 300 series chromium - nickel austenitic stainless steel (301,304,304L, 321,302,303,316,316L, 317L, 314,309S, 310,310S); special stainless steel (630,631,632 , 840,904L). Meanwhile with Baosteel, TISCO, Lianzhong, Wing Tai and other large steel enterprises friendship cooperation, networking sales, to provide users with greater choice, providing one-stop sourcing material. Supply complete specifications, a wide variety. (Note: L on behalf of low-carbon, low carbon content, such as 304L .S than 304 representatives of more than 310 high temperature, such as high temperature and strong 310S high temperature stainless steel:.. 317L, 314,309S, 310,310S.630 and 631 horses martensitic precipitation hardening stainless steel, the performance characteristics can adjust the intensity level is .840 and a super austenitic stainless steel 904L, with superior corrosion resistance and high temperature performance (maximum temperature above 2000 degrees) by changes in heat treatment process [stainless steel rod class] [product type], because with superior corrosion resistance so much for the acid container): cold drawn steel bars, bright bars, ground rods, hot rods, large diameter black stick, easy to drive stick. , green bar] [product shape: round, square bar, flat, hexagonal rods, octagonal stick [specifications]: Rods: Ф1mm ~ Ф320mm square bar: 3 * 3 to 150 * 150 hexagonal rods: S1mm ~ S77mm [ Bar surface]: black face, polished surface, polished surface (6K, 8K mirror) Product Material: 304,304L, 304F, 321,303 (303CU), 316,316L, 316Ti, 316F, 314,310S , 630,840,904L, 420J2 like. [Origin selection]: domestic (Zhang Pu, Baosteel, TISCO, Lianzhong), imports (Posco, Nippon Steel, ThyssenKrupp, British Grameen America) [bar] Features: Product specifications Large, round rod high straight and high, small size and high precision tolerances (gyrating up to 0.01mm); good wood surface quality (no cracks, no pitting); microstructure, stable performance; chemical composition and stability pure steel, low inclusion content. [Quality assurance]: in line with user requirements proposed by the mechanical properties and chemical composition, to meet the relevant national performance standards, provide objective and true material certificates and other relevant test reports, such as: SGS environmental certification, factory inspection report and its. [Applications]: machinery parts, auto parts, boiler accessories, architectural, bridges, steel manufacturing, solar energy, electronics, computer accessories, such as mobile phones. Note: generally divided :( stainless steel bright bars and black bars), shiny black face than face expensive large-diameter rods, mostly black rod can be classified according to the nature and purpose :( ground rods, easy. Car rods, polished rods), where 303 (303CU), 304F, 316F for easy turning-type material, mainly used for automatic lathe turning, drilling.
