Peb txhua tus paub hais tias lub npe hu ua stainless steel fasteners lossis cov hlau tsis muaj steel hlau, yog siv rau cov khoom siv hlau tsis zoo (xws li 300 series ntawm austenitic stainless hlau) los ntawm cov txheej txheem (xws li: txias npe, tsis siv lub tshuab lathes, txias extrusion, thiab lwm yam) tsim. Cov steel hlau fasteners muaj ntau hom kev siv thiab ntau txoj hau kev. Dab tsi yog qhov sib txheeb ntawm cov tshuaj muaj pes tsawg leeg thiab kev ua kom tsis muaj steel hlau? raws li nram no:
1. Cov pa carbon C yuav ua rau kom muaj zog thiab muaj zog, cov ntsiab lus siab dhau los yuav txo nws txoj kev lag luam thiab kev xeb hluav taws
2, Chromium Cr tuaj yeem ua kom tsis muaj corrosion, oxidation kuj, lis caiv, nce zog, hardness thiab hnav coj
3, nickel Ni tuaj yeem ua rau kom muaj qhov kub siab, ua kom muaj zog, txo qhov txias zog ua haujlwm
4, molybdenum Mo tsub kom muaj zog, zoo heev corrosion tsis mus oxides thiab seawater
5, Copper Cu tswj kev txias thiab tsim kom muaj cov khoom sib nqus
