Martensitic chromium-nickel steel muaj xws li martensitic nag lossis daus hardening stainless hlau, semi- austenitic nag lossis daus hardening stainless hlau, thiab maraging stainless hlau. Cov no yog lub zog siab lossis ultra siab zog stainless hlau. Cov hlau no muaj cov ntsiab lus carbon tsawg (tsawg dua 0.10%) thiab muaj cov nickel. Qee qib kuj muaj cov ntsiab lus siab dua xws li molybdenum thiab tooj liab. Yog li ntawd, cov hlau muaj lub zog siab, thiab kev sib xyaw ua ke ntawm lub zog thiab tawv, corrosion kuj thiab weldability yog superior rau martensitic chromium hlau. Crl7Ni2 yog cov feem ntau siv tsawg nickel martensitic stainless hlau.
Martensitic nag lossis daus hardening stainless hlau feem ntau muaj xws li Al, Ti, thiab Cu. Nws yog ua kom lub zog ntawm cov hlau los ntawm nag lossis daus hardening ntawm martensite matrix los ntawm nag lossis daus hardening, xws li Crl7Ni4Cu4. Lub semi-austenitic (los yog semi-martensitic) nag lossis daus hardened stainless hlau tseem yog austenitic vim lub xeev quenched. Yog li ntawd, lub xeev quenched tseem tuaj yeem txias - tsim thiab ntxiv dag zog los ntawm cov txheej txheem xws li kev kho nruab nrab thiab kev laus. Nyob rau hauv txoj kev no, austenite nyob rau hauv martensitic nag lossis daus hardening stainless hlau tuaj yeem ncaj qha hloov mus rau hauv martensite tom qab quenching, uas ua rau muaj qhov tsis zoo uas tom qab ua haujlwm nyuaj. Feem ntau siv cov qib steel yog 0Crl7Ni7AI, 0Crl5Ni7M02A1, thiab lwm yam. Cov hlau zoo li no muaj lub zog siab, feem ntau yog li ntawm 1200 txog 1400 MPa, thiab feem ntau siv los ua cov txheej txheem uas yuav tsum tau muaj kev tiv thaiv corrosion tsawg dua tab sis yuav tsum muaj lub zog siab, xws li cov tawv nqaij dav hlau.
