SUS420J2 stainless hlau seamless yeeb nkab yog tsim raws li Japanese cov qauv kev lag luam thiab belongs rau 420 series stainless hlau. Nws muaj siab hardness, lub zog thiab hnav tsis kam. Nyob rau tib lub sij hawm, nws muaj corrosion kuj zoo nyob rau hauv tej yam kev mob. Ib txheej ntawm oxide zaj duab xis yog tsim rau ntawm qhov chaw, uas tuaj yeem ua lub luag haujlwm tiv thaiv corrosion.
Tsis tas li ntawd, SUS420J2 steel yeeb nkab muaj siab hardness thiab tsim nyog rau kev tsim riam, txiav cov cuab yeej thiab lwm yam uas yuav tsum tau muaj siab hardness thiab hnav tsis kam.
