Dab tsi yog 1.4021 stainless hlau?
DIN 1.4021 Cov hlau tsis muaj ntsej muag, tseem muaj lub cim stainless, yog lub martensitic stainless hlau nrog cov cov ntsiab lus carbon ntau (0.16-0.25%) thiab lub siab chromium cov ntsiab lus (12-14%). Cov muaj pes tsawg no muab nws cov cuab yeej zoo heev, suav nrog kev ua kom muaj zog thiab hardness tom qab tempering, nrog rau zoo corrosion tsis kam. Nws yog feem ntau siv nyob rau hauv cov ntawv thov uas xav tau kev ua ke ntawm lub zog, tawv tawv, thiab muaj kev txhim kho corrosion tsawg.
