S355J2H seamless hlau yeeb nkabEN10210Cov yeeb nkab hlau tsis muaj seamless hauv Tebchaws Europe.

S355J2H seamless steel yeeb nkab yog ib hom hlau uas tau teev tseg hauvBS EN 10210-1:2006"Cov kav dej hlau tsis yog hlau thiab cov hlau zoo uas kub thiab ua los ntawm cov hlau zoo (cov khoom siv hollow core) Ntu 1: Cov kev cai xa khoom", uas xav tau -20 lub zog cuam tshuam Mus txog ntau dua 27J, nws yog cov hlau tsis tshua muaj zog nrog cov yas zoo thiab cov khoom siv cuam tshuam.

Cov yeeb nkab hlau S355J2H feem ntau yog siv rau hauv kev tsim kho vaj tse hlau uas tsis kub heev, kev tsim kho chaw ua si loj, thiab kev tsim cov thawv uas tsis kub heev. Cov yeeb nkab hlau S355J2H kuj tseem siv tau rau hauv kev tsim kho cov chaw roj hauv hiav txwv. Cov yeeb nkab hlau S355J2H muaj kev ua haujlwm zoo thiab tuaj yeem ua cov khoom siv kho tshuab uas tsis kub heev.

Tus qauv European EN10025-2 hais tias lo lus pib nrog S yog cov hlau ua vaj tse, thiab 355 uas ua raws li ntawd txhais tau tias qhov tsawg kawg nkaus ntawm qhov kub thiab txias yog 355MPa.

S355J2H yog tus qauv European. Cov khoom siv no yog cov khoom siv uas tsis kub heev. Nws tus qauv siv yogEN10210, feem ntau yog rau cov kav hlau tsis sib xws thiab cov kav hlau tsis sib xws thiab cov kav hlau tsis sib xws.

Tsis tas li ntawd xwb, peb lub tuam txhab kuj ua haujlwm lwm cov kav dej kho tshuab thiab cov kav dej qauv, xws liASTM A519: ASTM A519-2006Tus qauv feem ntau yog siv rau cov kav hlau tsis muaj seamless, cov kav hlau carbon thiab cov kav hlau alloy rau cov tshuab. Cov kav hlau alloy feem ntau suav nrog
1018, 1026, 8620, 4130, 4140, thiab lwm yam.

ASTM A53/A53MASTM A53 yog tus qauv uas tau tshaj tawm los ntawm American Society for Testing and Materials (ASTM) uas qhia txog cov yeeb nkab carbon dub lossis galvanized, seamless lossis welded. Nws yog ib qho ntawm cov qauv yeeb nkab hlau uas siv dav tshaj plaws hauv ntiaj teb thiab siv dav hauv roj, roj av, tshuaj lom neeg, kev tsim kho thiab lwm yam lag luam.
