Ib qho ntawm cov yam ntxwv tseem ceeb ntawm 25CrMo4 steel daim hlau hauv kev siv cov txheej txheem alloy yog lawv cov hardenability siab, uas yog qhia tshwj xeeb hauv cov hauv qab no. Cov yam ntxwv no ua rau lawv hloov mus rau cov kev ua haujlwm nyuaj thiab cov khoom loj - nplai:

I. Core Manifestations ntawm Hardenability

Hardenability yog hais txog lub peev xwm ntawm cov hlau kom tau txais cov qauv martensite thaum quenching. Lub siab hardenability ntawm 25CrMo4 feem ntau yog manifested raws li nram no:

 

Uniform hardening ntawm cov ntu loj: Txawm tias cov hlau phaj nrog lub thickness kuj loj (xws li ntau tshaj 50mm), cov tub ntxhais tseem tuaj yeem tau txais qhov feem pua ​​​​ntawm cov qauv martensite thaum lub sij hawm tag nrho quenching, es tsis yog tsuas yog deg hardening. Qhov no ua kom muaj kev ua tau zoo ntawm tag nrho cov khoom thiab zam kev ua haujlwm tsis txaus hauv cov tub ntxhais vim qhov loj ntawm ntu ntau dhau.

Cov txheej txheem dav adaptability: Nws tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws nyob rau hauv qhov sib txawv ntawm cov cua txias (xws li dej txias, roj txias lossis txawm tias cua txias), uas txo cov kev cai nruj ntawm quenching media thiab ua kom yooj yim rau cov txheej txheem ntau lawm.

 

 

 

 

 

 

 

 

II. Ua rau High Hardenability

Nws hardenability kom zoo dua stems los ntawm synergistic nyhuv ntawm alloying ntsiab:

 

Chromium (Cr): Raws li cov carbide muaj zog - tsim cov khoom, nws tuaj yeem txhim kho qhov ruaj khov ntawm austenite, ncua pearlite transformation, nce lub sij hawm rau kev tsim martensite, thiab nthuav cov hardenability ntau yam.

Molybdenum (hli): Thaum refining nplej, nws ntxiv inhibits austenite decomposition thiab txhim khu kev ruaj ntseg ntawm undercooled austenite, tshwj xeeb tshaj yog muaj cov nyhuv tseem ceeb nyob rau hauv nruab nrab - kub ntau yam (pearlite transformation interval), thiab ua ib tug "superposition effect" nrog chromium.

Cov pa roj carbon (C): Tus nqi tsim nyog ntawm carbon (0.22% - 0.29%) muab lub hauv paus rau kev hloov pauv martensite. Nws ua ke nrog cov ntsiab lus alloying los tsim cov carbide ruaj khov, uas tsis tsuas yog ua kom tawv tawv tab sis kuj zam qhov brittleness los ntawm cov ntsiab lus siab carbon.
