S355J2H seamless steel yeeb nkabTS EN 10210European txheem seamless steel yeeb nkab.

S355J2H seamless steel yeeb nkab yog hom hlau uas tau teev tseg hauvTS EN 10210-1: 2006"Non-alloy thiab fine-grained structural steel hot-formed structural pipes (hollow core material) Part 1: Technical delivery requirements", uas yuav tsum tau -20 feem cuam tshuam lub zog ncav cuag ntau tshaj 27J, nws yog ib tug low-alloy high-strength steel nrog zoo plasticity thiab cuam tshuam toughness.

S355J2H seamless steel yeeb nkab yog tsuas yog siv nyob rau hauv low-temperature climate steel qauv engineering, loj-scale kev ua si chaw ntau pob kev tsim kho, thiab low-temperature thawv manufacturing. S355J2H steel yeeb nkab kuj tuaj yeem siv rau hauv kev tsim kho cov roj av. S355J2H steel yeeb nkab muaj kev ua tau zoo thiab tuaj yeem ua cov khoom siv hluav taws xob qis.

Cov txheej txheem European EN10025-2 qhia tias lo lus pib nrog S yog cov qauv hlau, thiab 355 uas ua raws li no txhais tau hais tias qhov tsawg kawg nkaus lub zog ntawm chav tsev kub yog 355MPa.

S355J2H yog tus qauv European. Cov khoom no yog cov khoom siv kub-kub. Nws tus qauv siv yogTS EN 10210, feem ntau yog rau seamless steel kav thiab seamless square thiab rectangular kav.

Tsis tas li ntawd, peb lub tuam txhab kuj tseem ua haujlwm rau lwm cov kav dej thiab cov kav dej, xws liASTM A519 Cov Lus Qhia Tshwj Xeeb: ASTM A519-2006 Kev Tswj Xyuas Kev Tswj Xyuastus qauv yog tsuas yog siv rau seamless steel kav, carbon steel kav thiab alloy mechanical kav rau machinery. Alloy mechanical pipes mas suav nrog
1018, 1026, 8620, 4130, 4140, thiab lwm yam.
