Txheej txheem cej luam ntawm ST37-2G standard
ST37-2G yog German tus qauv qis carbon structural steel ua raws li DIN 17100. Hom steel no yog siv dav hauv kev tsim kho, tshuab, nkoj tsim thiab lwm yam lag luam hauv tsev thiab txawv teb chaws, thiab muaj kev ua haujlwm zoo thiab kev ua haujlwm zoo.
2. Tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm ST37-2G steel
Cov tshuaj muaj pes tsawg leeg ntawm ST37-2G steel feem ntau suav nrog carbon (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) thiab lwm yam. Nws cov khoom siv tshuab muaj raws li hauv qab no: tensile zog> 400MPa, yield zog ntau dua los yog sib npaug rau 240MPa, thiab elongation> 24%.
3. Daim ntawv thov teb ntawm ST37-2G steel
ST37-2G steel yog dav siv hauv kev tsim vaj tsev, txuas hniav, nkoj siab, tshuab hnyav, nkoj thiab lwm yam kev lag luam vim nws cov khoom zoo heev. Tshwj xeeb tshaj yog nyob rau hauv cov tsev siab siab thiab cov choj ntev ntev, ST37-2G steel tau dhau los ua cov hlau xaiv vim nws lub zog siab thiab kev ua haujlwm zoo vuam.
4. Kev ceev faj rau kev ua thiab vuam ntawm ST37-2G steel
1. Thaum lub sij hawm ua, ST37-2G steel muaj kev ua tau zoo, tab sis yuav tsum tau them nyiaj rau deformation thiab tawg thaum txiav, vuam thiab kho cua sov.
2. Thaum lub sij hawm vuam txheej txheem, cov txheej txheem vuam tsim nyog thiab cov khoom siv vuam yuav tsum raug xaiv kom ntseeg tau tias qhov kev ua tau zoo ntawm cov welded sib koom tsis qis dua li ntawm cov hlau puag. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau kev tswj cov vuam tam sim no, vuam ceev thiab lub sijhawm txias kom tsis txhob muaj qhov tsis zoo ntawm vuam.
5. Kev sib piv ntawm cov qauv suav nrog cov qauv thiab txawv teb chaws
kuv lub teb chaws tau tsim cov qauv sib raug rau ST37-2G steel, xws li GB/T 1591-2018 "Low Alloy High-Strength Structural Steel" thiab lwm yam. Piv nrog rau cov qauv txawv teb chaws, peb lub teb chaws cov qauv yog qhov tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, tab sis muaj qhov sib txawv ntawm qee cov ntsiab lus.
