T10A Carbon Tool Steels

 

 

 

 

Cov yam ntxwv cuam tshuam rau kev hnav tsis kam ntawm T10A cov cuab yeej steel yog raws li hauv qab no:

 

1. Tshuaj muaj pes tsawg leeg:

 

Cov ntsiab lus carbon: Cov ntsiab lus carbon ntau dua feem ntau ua rau muaj zog ntxiv thiab hnav tsis kam. Hauv T10A steel, qib carbon tsim nyog ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws lub peev xwm los tiv thaiv hnav.

Alloying ntsiab: Me me ntawm alloying ntsiab xws li manganese, silicon, thiab chromium tuaj yeem cuam tshuam qhov hnav tsis kam. Piv txwv li, manganese tuaj yeem txhim kho hardenability thiab toughness, thaum chromium tuaj yeem txhim kho hardness thiab corrosion kuj, indirectly cuam tshuam rau hnav tsis kam.

 

2. Kev kho cua sov:

 

quenching thiab tempering: Cov txheej txheem kho cua sov muaj qhov cuam tshuam loj heev rau microstructure thiab txhua yam khoom ntawm T10A steel. Kev quenching raws li tempering yuav optimize hardness thiab toughness, yog li txhim kho hnav tsis kam. Kev kho cua sov tsis raug tuaj yeem ua rau tsis txaus hardness lossis brittleness ntau dhau, txo qhov hnav tsis kam.

Txias tus nqi: Tus nqi ntawm cov hlau txias thaum lub sij hawm quenching tuaj yeem cuam tshuam qhov tsim ntawm microstructures zoo li martensite. Kev tswj qhov txias txias yog qhov tseem ceeb rau kev ua tiav qhov xav tau hardness thiab hnav tsis kam.

 

3. Microstructure:

 

Cov qoob loo loj: Cov qoob loo zoo dua tuaj yeem txhim kho kev hnav tsis kam vim lawv muab cov ciam teb ntau dua, uas tuaj yeem cuam tshuam kev nthuav tawm ntawm cov kab nrib pleb thiab hnav. Coarse nplej tuaj yeem ua rau txo qis hnav tsis kam.

Theem muaj pes tsawg leeg: Muaj cov theem sib txawv xws li martensite, ferrite, thiab carbide tuaj yeem cuam tshuam rau hnav tsis kam. Martensite feem ntau nyuaj thiab hnav-tiv taus ntau dua li ferrite. Kev faib tawm thiab qhov loj ntawm carbides kuj ua lub luag haujlwm hauv kev txiav txim siab coj cwj pwm.

 

4. Cov xwm txheej ua haujlwm:

 

Load thiab siab: siab loads thiab pressures nce tus nqi hnav. T10A steel yuav tsum muaj peev xwm tiv taus lub zog siv yam tsis muaj deformation ntau dhau lossis hnav.

zawv zawg ceev: Qhov ceev ntawm ob qhov chaw swb tawm tsam ib leeg tuaj yeem cuam tshuam kev hnav. Kev nrawm dua tuaj yeem ua rau muaj kev sib txhuam ntau dua thiab hnav hnyav dua.

Ib puag ncig: Yam xws li kub, av noo, thiab muaj cov khoom corrosive tuaj yeem cuam tshuam rau hnav. Corrosive ib puag ncig tuaj yeem nrawm hnav los ntawm kev tawm tsam cov hlau nto.

 

5. Kev kho deg:

 

Txheej: Siv cov txheej txheej xws li cov txheej tawv tawv (xws li, titanium nitride), tuaj yeem txhim kho qhov hnav tsis kam ntawm T10A steel los ntawm kev muab cov txheej tiv thaiv uas txo cov kev sib txhuam thiab hnav.

Surface hardening: Cov txheej txheem zoo li cov ntaub ntawv tawv tawv lossis nitriding tuaj yeem ua rau cov tawv tawv ntawm txheej txheej, txhim kho hnav tsis kam thaum tuav cov tub ntxhais tougher.
