Khoom Description
1.4057 yog ib hom hlau nrog zoo zog thiab toughness nyob rau hauv martensitic stainless hlau. Nws yog ib qho qis carbon chrome-nickel hom corrosion resistant steel nrog siab zog thiab hardness. Nws muaj kev tiv thaiv corrosion zoo rau oxidizing acids (nitric acid ntawm qhov kub thiab txias, feem ntau cov organic acids) thiab cov organic acid aqueous tov Sub-temperature quenching tuaj yeem cuam tshuam qhov kub thiab txias ntawm cov hlau. Nws tuaj yeem txo qhov kev hloov pauv kub ntawm cov hlau, txhim kho qhov toughness, hloov qhov tawg morphology los ntawm hom quasi-cleavage mus rau hom dimple, thiab hloov cov ntsiab lus alloy mus rau matrix thiab δ- cov degree enrichment nyob rau hauv ferrite nce, uas tuaj yeem txhim kho cov khoom siv hlau. toughness ntawm steel thaum tuav lub zog siab. Txawm li cas los xij, cov hlau no tsis zoo weldability thiab nws yooj yim tawg, yog li nws tsis haum rau vuam thaum tsim cov cuab yeej.

1.4057 / 431 Cov Cuab Yeej Hlau Cov yam ntxwv
1.4057 stainless hlau feem ntau muaj: 15 - 17 feem pua chromium; 2 feem pua - 2.5 feem pua nickel; 0.12 - 0.22 feem pua carbon. Nws kuj tseem muaj me me ntawm silicon, molybdenum thiab phosphorus.
Chromium yog lub ntsiab alloying ntawm martensitic 1.4057 stainless hlau, uas inherently muaj nruab nrab corrosion tsis kam rau cov ntaub ntawv uas muaj zog thiab hardness. Feem ntau, npib tsib xee nrog ib qho concentration ntawm 2 - 2.5 feem pua yog ntxiv los ua ib qho chaw ruaj khov kom ntseeg tau tias cov hlau martensitic tswj nws qhov hnyav thaum kho cua sov, yog li tso cai rau kev tsim khoom ntawm ntau hom kev tiv thaiv.
1.4057 m martensitic stainless hlau feem ntau tsis nco qab, tej zaum vim lawv qhov kev thov tsis siab piv nrog austenitic thiab ferritic stainless hlau. Txawm li cas los xij, lawv feem ntau ua lub luag haujlwm loj thiab feem ntau tsis paub txog hauv cov txheej txheem niaj hnub no. Lub zog tau los ntawm kev kho cua sov yog nyob ntawm cov ntsiab lus carbon ntawm cov hlau. Kev nce cov ntsiab lus carbon yuav ua rau muaj peev xwm hardness thiab lub zog, tab sis yuav txo qhov toughness thiab ductility.
Cov qib carbon siab dua tuaj yeem raug kho kom sov rau qhov hardness txog li 60 HRC. Qhov zoo tshaj plaws corrosion kuj yuav ua tiav nyob rau hauv kev kho cua sov, hardening thiab tempering tej yam kev mob. Lwm cov qib martensitic yog tsim los ntawm kev ntxiv npib tsib xee thiab nitrogen, tab sis cov ntsiab lus ntawm cov pa roj carbon tsawg dua cov qib ib txwm muaj. 431 (1.4057) stainless hlau muaj zoo weldability, toughness thiab corrosion kuj.
