1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel

 

 

Dab tsi yog cov yam ntxwv ntawm 1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel?

 

Lub 1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel muaj cov yam ntxwv hauv qab no:

 

Cov yam ntxwv coj los ntawm cov tshuaj muaj pes tsawg leeg:

High hardness foundation: Cov ntsiab lus ntawm cov pa roj carbon monoxide yog ib qho tseem ceeb los xyuas kom meej qhov hardness ntawm cov hlau. Nws muab lub hauv paus siab hardness rau cov hlau, ua kom nws muaj kev ruaj ntseg zoo thiab hnav tsis kam thaum ua thiab siv, thiab tuaj yeem tiv taus ntau dua thiab kev sib txhuam.

Zoo kub tsis kam: Lub xub ntiag ntawm cov khoom xws li tungsten thiab chromium txhim kho cov cua sov ntawm cov hlau. Qhov no ua rau cov hlau tseem muaj zog thiab muaj zog ntawm qhov kub thiab txias thiab tsis yooj yim rau soften thiab deform. Nws yog qhov tsim nyog rau cov cuab yeej lossis qhov chaw ua haujlwm nyob rau hauv qhov kub thiab txias.

Toughness guarantee: Qhov sib ntxiv ntawm vanadium pab txhim kho lub toughness ntawm cov hlau. Thaum raug cuam tshuam los yog kev vibration, cov hlau tuaj yeem nqus tau lub zog yam tsis muaj kev tawg. Qhov no yog qhov tseem ceeb heev rau kev pabcuam lub neej thiab kev ntseeg siab ntawm cov cuab yeej, tshwj xeeb tshaj yog nyob rau hauv qee qhov kev thov uas cuam tshuam cov loads, xws li xuas nrig ntaus thiab cov cuab yeej txiav.

Cov yam ntxwv nyob rau hauv cov nqe lus ntawm mechanical zog:

Sib npaug siab hardness: Feem ntau, qhov hardness nyob nruab nrab ntawm 58 - 62 HRC. Nws belongs rau cov ntaub ntawv uas muaj kuj siab hardness. Qhov no ua rau nws ua tau zoo txiav thiab ua lwm yam ntaub ntawv softer, thiab nws tsis yooj yim rau hnav thiab deform thaum siv, tswj kev ua haujlwm zoo.

Zoo tensile zog: Lub zog tensile yog li ntawm 1500MPa, uas txhais tau hais tias cov hlau tuaj yeem tiv taus lub zog tensile ntau dua yam tsis muaj kev tawg, ua kom lub zog thiab ruaj khov ntawm cov cuab yeej thaum siv.

Zoo toughness thiab elongation: Qhov elongation feem ntau yog nyob nruab nrab ntawm 10% - 15%, qhia zoo toughness. Qhov no tso cai rau cov hlau kom deform mus rau qee qhov yam tsis muaj kev tawg thaum raug rau sab nraud quab yuam. Rau qee cov cuab yeej lossis qhov chaw uas yuav tsum tau dais dabtsi yog khoov, torsion thiab lwm yam kev ntxhov siab, qhov no yog qhov tseem ceeb ntawm kev ua tau zoo.

Cov yam ntxwv ntawm kev kho cua sov:

Muaj zog cua sov kho: Cov hlau no tuaj yeem txhim kho nws cov kev ua tau zoo los ntawm ntau txoj kev kho cua sov. Piv txwv li, normalizing kev kho mob tuaj yeem txhim kho hardness thiab lub zog, thaum txhim kho cov cua sov thiab hnav tsis kam; quenching kev kho mob tuaj yeem ua kom txias cov khoom kom tau txais siab hardness thiab lub zog; tempering kho tuaj yeem kho qhov hardness tom qab quenching kom tau zoo dua toughness thiab ductility.

Zoo adaptability ntawm kev kho cua sov txheej txheem: Thaum lub sij hawm kev kho cua sov, kev tswj qhov kub thiab lub sij hawm kuj hloov tau. Nws tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb thiab kev siv cov xwm txheej kom tau txais kev sib xyaw ua ke zoo tshaj plaws.

Txheej txheem kev ua tau zoo:

Kev ua tau zoo: Nws muaj cov txheej txheem zoo thiab tuaj yeem ua rau ntau yam duab thiab qhov ntau thiab tsawg ntawm cov cuab yeej lossis qhov chaw los ntawm ntau txoj kev ua haujlwm xws li forging, dov, thiab txiav. Thaum lub sijhawm ua cov txheej txheem, kev ua haujlwm nyuaj ntawm cov hlau yog nruab nrab. Nws tsis yog ib qho nyuaj rau kev ua haujlwm los yog nws yog mos dhau los cuam tshuam rau kev ua tiav thiab qhov zoo ntawm qhov chaw.

Zoo dimension stability: Cov txheej txheem steel muaj qhov zoo ntawm qhov ruaj khov thiab tsis yooj yim los hloov qhov loj me thaum siv, kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm cov cuab yeej lossis cov khoom.

Lwm yam ntxwv:

General corrosion kuj: Nws muaj qee yam corrosion kuj nyob rau hauv ib puag ncig zoo tib yam. Txawm li cas los xij, nyob rau hauv qee qhov hnyav corrosive ib puag ncig, kev kho saum npoo ntxiv lossis kev tiv thaiv yuav tsum tau ua kom nws cov corrosion kuj.

Kev ua tau zoo tshaj plaws: Nws ua ke ntau yam khoom xws li siab hardness, zoo toughness, tshav kub tsis kam, thiab processability, ua rau nws yog ib tug zoo steel lug siv nyob rau hauv cov cuab yeej tsim, pwm manufacturing, mechanical processing thiab lwm yam teb.
