420 yog martensitic stainless hlau nrog 12 feem pua Chromium uas txaus los muab cov khoom zoo corrosive. .Nws yog qhov zoo tshaj plaws corrosive kuj yog thaum hardened thiab nto yog av los yog polished.Nws muaj zoo ductility nyob rau hauv lub annealed mob tab sis yuav hardened mus txog 500HB (siab tshaj ntawm cov chromium qib). Cov qib Martensitic paub txog qhov nyuaj siab thiab cov nyiaj pub dawb yuav tsum tau ua rau cov weldability tsis zoo thiab feem ntau yog nyiaj pub dawb rau qhov kawg harden thiab temper kho.
Hlau yog hlau nplaum thiab vuam tsis pom zoo.
