Khoom Taw qhia

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. Xws li cov hlau feem ntau smelted los ntawm converter los yog qhib hearth rauv. Lub ntsiab raw khoom yog molten hlau thiab seem hlau. Cov ntsiab lus ntawm sulfur thiab phosphorus nyob rau hauv steel yog siab dua li ntawm high quality carbon structural steel. Feem ntau, sulfur tsawg dua lossis sib npaug rau 0.050% thiab phosphorus tsawg dua lossis sib npaug li 0.045%.

Cov ntsiab lus ntawm lwm yam alloying ntsiab coj mus rau hauv cov hlau los ntawm raw cov ntaub ntawv, xws li chromium, nickel thiab tooj liab, feem ntau tsis ntau tshaj 0.30%. Raws li qhov muaj pes tsawg leeg thiab kev ua tau zoo, cov qib ntawm cov hlau no yog 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 cov khoom, tab sis tsis tshua muaj zog yuav folded.

Tus txheej txheem tswj hwm: GB / T 3091-2015 "welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab" GB / T 13793-2016 "txoj hlua hluav taws xob welded steel yeeb nkab"
