A514GrE A514GrF daim ntawv hlau kaum
A514GrE A514GrF lub kaum sab xis steel
A514 yog quenched thiab tempered siab zog weldable steel raws li ASTM tus qauv, uas yog tsuas yog siv nyob rau hauv cov chaw uas yuav tsum tau siab tensile zog thiab siab yield, engineering tsheb lifting zog, thiab khib thiab pinion rau offshore platforms.
Muaj yim qib sib txawv ntawm ASTM A514: A514 GrA, A514 GrB, A514 GrE, A514 GrF, A514 GrH, A514 GrP, A514 GrQ, A514 GrS. Thicknesses, tshuaj muaj pes tsawg leeg, thiab cov khoom ntawm cov qib sib txawv ntawm A514 steel sib txawv.
Cov tshuaj muaj pes tsawg leeg ntawm A514GrE lub kaum sab xis steel kuj yog ib qho laj thawj tseem ceeb rau nws cov khoom zoo heev. Nws tsuas yog muaj carbon, manganese, silicon, phosphorus, sulfur, chromium, npib tsib xee, molybdenum thiab lwm yam khoom. Ntawm lawv, cov ntsiab lus carbon tsawg, 0.12%-0.21%, thiab cov ntsiab lus manganese siab, 0.70%-1.{{8 }}%. Kev sib xyaw ntawm cov ntsiab lus no tuaj yeem ua kom lub zog thiab tawv tawv ntawm cov hlau, thiab tib lub sijhawm txhim kho nws cov corrosion thiab hnav tsis kam.
A514GrE steel daim ntaub ntawv: A514GrE steel phaj yog lub zog muaj zog alloy hlau, uas muaj cov khoom siv zoo heev thiab tshuaj lom neeg muaj pes tsawg leeg. Cov hlau no tau siv dav hauv kev tsim cov nkoj, txuas hniav, kev tsim kho thiab cov cuab yeej siv tshuab.
Lub hardness ntawm A514GrF alloy lub kaum sab xis steel yog nyob nruab nrab ntawm 235-290, cov tawm los yog ntau tshaj 630MPa, thiab lub tensile lub zog yog ntau tshaj 700MPa.Qhov no hom ntawm steel yog me ntsis nyuaj rau txheej txheem.
