Kev xaiv cov khoom siv stud bolt zoo yuav tsum tau xav txog ntau yam xws li kev ua haujlwm ib puag ncig, kev xav tau ntawm kev ua haujlwm, kev tiv thaiv corrosion, thiab tus nqi. Cov ntaub ntawv sib txawv tsim nyog rau kev ua haujlwm sib txawv.
1. Carbon Steel: Tus nqi siab -kev ua tau zoo, haum rau ib puag ncig.
Nta: Lub zog nruab nrab, tsis tshua muaj nqi, zoo machinability, tab sis nws muaj corrosion.
Cov xwm txheej siv tau: Qhuav, qhov kub thiab txias, tsis yog -ib puag ncig corrosive, xws li cov khoom siv hauv tsev, cov qauv hauv tsev, rooj tog sib txuas, thiab lwm yam.
Qib Qib: Feem ntau 4.6 thiab 8.8 qib, nrog 8.8 thiab siab dua yog siab - lub zog bolts haum rau cov qauv kev sib txuas.
2. Stainless Hlau: Muaj zog corrosion kuj, haum rau hnyav ib puag ncig.
Nta: xeb- pov thawj, kua qaub thiab alkali resistant, noo noo resistant, du nto, lub neej ntev kev pab cuam.
Hom Qib:
SUS304 (A2-70): General-purpose stainless hlau, haum rau cov cheeb tsam corrosive, xws li cov khoom noj khoom haus thiab cov kav dej hauv tsev.
SUS316 (A4-70): Muaj cov molybdenum, muab kev tiv thaiv zoo rau cov tshuaj chloride ion corrosion, tsim nyog rau cov cheeb tsam corrosive xws li marine engineering, chemical engineering, thiab shipbuilding.
Qib Qib: Stainless hlau bolts yog cim nrog cov qib zog xws li "A2-70," qhov twg tus lej "70" qhia tias lub zog tensile ntawm 700 MPa.
3. Alloy Steel Khoom: Lub zog muaj zog thiab siab tawv, siv rau hauv kev ua haujlwm hnyav.
Nta: Lub zog, kub tsis kam, thiab qaug zog tiv thaiv tau txhim kho los ntawm kev ntxiv cov khoom sib xyaw xws li chromium, molybdenum, thiab vanadium. Tom qab kev kho cua sov, qib zog tuaj yeem ncav cuag 10.9 lossis txawm 12.9.
Cov xwm txheej siv tau: Cov choj, cov khoom siv cua tshuab, aerospace, siab - qhov cub kub, thiab lwm yam siab - load lossis huab cua kub ib puag ncig.
Cov Khoom Siv: 35CrMo, 42CrMo, SCM435, thiab lwm yam., muaj cov khoom siv zoo heev.
