Stainless hlau screws yog cais rau hauv austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau, thiab nag lossis daus hardened steel. Kev xaiv ntawm stainless hlau screws yog tseem principled. Txij ntawm qhov kev xam pom, cia koj xaiv cov hlau tsis muaj hau ntswj koj xav tau.
Tom qab kev qhia thiab kev saib xyuas ntawm tsib yam no, cov qhab nia, cov qib, yam ntxwv thiab cov khoom siv ntawm cov tsis muaj qab hau stainless hlau raug txiav txim siab.
Martensitic steel hlau
Hom 410 thiab 416 tuaj yeem ua kom sov-tau kho thiab ntxiv nrog rau qhov nyuaj ntawm 35 mus rau 45 HRC. Lawv muaj kev ua tau zoo thiab siv rau kev siv hluav taws xob-resistant thiab corrosion-resistant stainless hlau screws. Hom 416 yog me ntsis siab me ntsis ntawm leej faj thiab yog ib qho dawb-stainless hlau.
Hom 420, sulfur cov ntsiab lus R0.15%, txhim kho mechanical zog, kev kho kom sov, kho siab tshaj 53 ~ 58HRC, rau stainless hlau screws ntxiv zog dua.
Nag lossis daig hardening steel hlau
17-4PH, PH15-7Mo, lawv tuaj yeem siv nrog zog siab dua li niaj zaus 18-8 hom stainless hlau, thiab yog li ntawd siv rau siab zog, corrosion resistant stainless hlau stainless hlau screws.
A-286, ib cov qauv uas tsis muaj qauv stainless, muaj corrosion ntau dua li qhov feem ntau siv 18-8 stainless hlau thiab zoo mechanical zog rau kom txias. Siv ua ib lub zog, muaj zog-resistant, corrosion-resistant steel hlau ntsia hlau, nws yuav siv li 650 ~ 700 ° C.
