Q215 Steel Tube

Q215 steel yeeb nkab yog carbon structural steel (GB/700-1999), Q-yield, 215- yog qhov tsawg kawg nkaus yield point (σs) tus nqi ntawm qib no. Hom hlau no feem ntau yog smelted nyob rau hauv lub converter los yog qhib-hearth rauv, thiab cov ntaub ntawv tseem ceeb yog molten hlau thiab seem hlau. Cov sulfur thiab phosphorus cov ntsiab lus nyob rau hauv cov hlau yog siab dua li ntawm high-zoo carbon structural steel, feem ntau sulfur tsawg dua los yog sib npaug rau 0.050%, phosphorus Tsawg dua los yog sib npaug rau 0.045%.
Cov ntsiab lus ntawm lwm yam alloying ntsiab xws li chromium, npib tsib xee, thiab tooj liab coj mus rau hauv cov hlau los ntawm raw cov ntaub ntawv feem ntau tsis tshaj 0.30%. Raws li qhov muaj pes tsawg leeg thiab kev ua tau zoo, cov qib ntawm cov hlau no suav nrog Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 thiab lwm qib steel. Cov yam ntxwv tseem ceeb yog siab plasticity, toughness thiab weldability, zoo siab ua kev ua tau zoo, tab sis tsis tshua muaj zog thiab bendable.
General welded kav: General welded kav yog siv los thauj cov dej uas tsis tshua muaj siab. Ua los ntawm Q195A, Q215A, thiab Q235A steel. Nws kuj tseem tuaj yeem ua los ntawm lwm cov hlau tsis tshua muaj hlau uas yooj yim rau vuam. Cov kav hlau yuav tsum tau ua dej siab, khoov, flattening thiab lwm yam kev ntsuam xyuas, thiab muaj qee qhov kev xav tau rau qhov zoo. Feem ntau qhov kev xa khoom ntev yog 4-10m, thiab feem ntau yuav tsum tau xa hauv qhov ntev ntev (lossis ntau qhov ntev). Cov specifications ntawm welded kav yog qhia nyob rau hauv nominal diameters (mm los yog inches). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb txoj kab uas hla. Raws li cov txheej txheem phab ntsa thickness, welded kav tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab. Cov kav hlau yog muab faib ua threaded thiab tsis yog xov raws li daim ntawv ntawm cov yeeb nkab kawg.
