ASTM A572 GR.42 ERW Yeeb Nkab
ASTM A572 specifications yog dab tsi?
ASTM A572 Specification yog tus qauv specification rau high-strength low-alloy niobium-vanadium structural steel siv nyob rau hauv dav siv lub tsev thiab cov qauv siv. ASTM A572 suav nrog tsib qib nrog cov txiaj ntsig tsawg kawg nkaus ntawm 42, 50, 55, 60, thiab 65 ksi.
ASTM A572 GR.42 ERW Carbon Steel Pipes yog cov kav hlau tsis kam welded (ERW) steel kav uas ua tau raws li ASTM A572 tus qauv specifications. Cov txheej txheem npog lub zog siab qis alloy (HSLA) cov qauv steel ntu, daim hlau thiab cov pas nrig,
Lub npe "GR.42" yog hais txog qib steel tshwj xeeb hauv ASTM A572 tus qauv. GR.42 steel muaj lub zog tawm los ntawm 42 ksi (txhiab phaus ib square inch) thiab lub zog tensile ntawm kwv yees li 60 ksi. Qhov no ua rau nws tsim nyog siv rau hauv cov qauv siv uas xav tau nruab nrab mus rau siab zog.
ASTM A572 GR.42 ncaj seam yeeb nkab muaj siab dabtsi yog khoov lub zog thiab tensile lub zog, nrog rau zoo toughness thiab weldability. Nws yog qhov tsim nyog rau ntau yam kev tsim vaj tsev uas yuav tsum tau tiv taus cov khoom hnyav dua thiab siab, xws li cov tsev, txuas hniav, thiab tsheb. , nkoj thiab lwm yam.
