ASTM A537 Qib 1 yog ib tug normalized carbon-manganese-silicon siab hlab ntsha steel tsim los muab ib tug sib npaug ntawm lub zog thiab toughness. Nws yog feem ntau siv rau hauv welded siab-muaj cov qauv uas ua haujlwm ntawm qhov nruab nrab thiab qis kub, qhov kev ua tau zoo thiab kev tiv thaiv rau cov pob txha tawg yog qhov tseem ceeb. Cov khoom siv zoo heev weldability, ua rau nws haum rau fabricating loj thiab complex hlab ntsha. Nws qhov toughness kuj tso cai rau nws tiv taus thermal cycling thiab qis-kub. Cov ntawv thov feem ntau suav nrog cov khoom siv hauv cov roj, roj, thiab kev lag luam petrochemical, nrog rau cov boilers, cov tso tsheb hlau luam, thiab lwm cov hlab ntsha siab uas yuav tsum muaj kev tswj xyuas kev ncaj ncees raws li qhov xav tau kev pabcuam.

Qhov sib npaug ntawm ASTM A537 CL 1 yog dab tsi?
ASTM A537 Chav Kawm 1 yog sib npaug rau ASME SA537 Cl. 1, EN P355GH, DIN 19Mn6, JIS SPV355, thiab lwm yam, sib koom cov khoom qub thiab tawm los ntawm 345-355 MPa rau cov hlab ntsha siab.
Qib 1 steel yog dab tsi?
"Class 1 steel" tsis yog ib hom tab sis hais txog cov kev faib tawm sib txawv, feem ntau ASTM A537 Class 1, cov pa roj carbon monoxide-manganese-silicon steel phaj rau cov hlab ntsha siab nrog lub zog siab thiab tawv, lossis cov qauv, Eurocode Class 1 cross-section, qhia txog kev tsim cov yas tag nrho. Nws kuj tseem tuaj yeem piav qhia txog qib ntawm cov hlau tsis muaj zog (carbide- kho) lossis txawm tias cov hlau tsis huv (hnyav, npaj).
