S235JR steel sib npaug yog dab tsi?
Sib npaug steels rauS235 JRASTM A36, DIN ST37-2, JIS SS400, thiab GB Q235B. Lwm cov hlau sib npaug suav nrog ASTM A283 C thiab ISO E235B, txawm hais tias cov khoom tshwj xeeb yuav txawv me ntsis ntawm cov qauv sib txawv. Cov no yog tag nrho cov kev siv cov qauv steel qib nrog cov khoom zoo sib xws thiab kev siv.
Suav sib npaug ntawm S235 yog dab tsi?
Suav tus qauv Q235B sib haum rau European tus qauv S235. Txawm hais tias lawv muaj cov tshuaj lom neeg zoo sib xws thiab cov khoom siv kho tshuab, Q235B tau txhais los ntawm Suav tus qauv GB / T 700, thaum S235 yog ib feem ntawm European tus qauv EN 10025.
S235JR khoom yog dab tsi?
S235steel yog weldable low-carbon manganese steel nrog rau kev cuam tshuam zoo (xws li ntawm sub-zero kub). Cov khoom no feem ntau yog muab rau hauv cov kev kho tsis zoo lossis tsis zoo thiab tuaj nyob rau hauv ntau yam sib txawv (qhia los ntawm cov ntawv ntxiv thiab / lossis tus lej) uas txawv me ntsis ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab. Nws cov machinability zoo ib yam li cov hlau tsis muaj - carbon hlau.
Qhov txawv ntawm s235 thiab s275 yog dab tsi?
Qhov sib txawv tseem ceeb ntawm S235thiab S275 steel lies nyob rau hauv lawv qhov tsawg kawg nkaus yield zog: S235 muaj qhov tsawg kawg nkaus yield zog ntawm 235 MPa, thaum S275 muaj qhov tsawg kawg nkaus yield zog ntawm 275 MPa. Qhov no txhais tau hais tias S275 muaj zog dua thiab feem ntau yog siv rau hauv cov ntawv thov xws li cov tsev siab -nce thiab txuas hniav, thaumS235yog tsim rau kev tsim kho dav dav thiab lub teeb yuag. Ob leeg yog cov qauv hlau uas zoo sib xws weldability thiab durability, tab sis S275 yog cov khoom siv muaj zog dua.
Dab tsi yog cov ntawv thov ntawm S235JR?
S235 JRyog ib qho qis- carbon structural steel uas tuaj yeem siv rau cov qauv siv xws li vuam, bolting, thiab riveting, nrog rau cov tsev, txuas hniav, nkoj, cov qauv tsheb, thiab kev tsim khoom ntawm ntau yam cuab yeej, cutters, pwm, thiab ntsuas ntsuas.
