Puas yog SUS420J2 stainless hlau hlau nplaum?
SUS420J2 stainless hlau yog hlau nplaum vim nws yog martensitic stainless hlau, uas muaj cov pa roj carbon ntau thiab cov qauv siv lead ua (ferrite) uas ua rau nws nyiam cov hlau nplaum, txawm tias tom qab kev kho cua sov rau hardening.
SUS420J2 vs SUS304 Stainless hlau: Corrosion Resistance
SUS420J2 stainless hlau muaj qhov nruab nrab corrosion tsis kam vim nws cov ntsiab lus chromium qis (12-14%) thiab cov ntsiab lus carbon siab, ua rau nws tsim nyog rau qhov chaw qhuav lossis me me corrosive, whereas SUS304 stainless hlau, nrog 18-20% chromium thiab 8-10.5% npib tsib xee, muab kev tiv thaiv corrosion zoo heev hauv kev siv tshuaj lom neeg, midity {9.
SUS420J2 Stainless hlau vs SUS304 Stainless hlau: Hardness
Tom qab kev kho cua sov, SUS420J2 stainless hlau tuaj yeem ua tiav qhov hardness txog li 500 HV, muab kev hnav zoo tshaj plaws rau cutlery, cov cuab yeej phais, thiab cov khoom siv kho tshuab, thaum SUS304 stainless hlau muaj qis hardness ntawm 150-200 HV, ua ntej ductility thiab corrosion kuj tshaj hnav lub zog.
SUS420J2 Stainless hlau vs SUS304: Weldability
SUS420J2 stainless hlau yog weldable tab sis yuav tsum tau ceev faj preheating thiab post-weld kho cua sov kom tsis txhob tawg vim nws cov qauv martensitic, whereas SUS304 stainless hlau, ua tag nrho austenitic, nthuav dav weldability nrog tsawg heev ntawm kev pheej hmoo ntawm intergranular corrosion, ua rau nws zoo tagnrho rau piping, tso tsheb hlau luam, thiab chemical processing khoom.
