Kev kho cua sov yog txheej txheem tseem ceeb rau SNCM815 steel los ua kom zoo dua nws cov khoom siv kho tshuab. Quenching thiab tempering yog feem ntau siv cov kev kho cua sov rau SNCM815 steel. Quenching muaj cua sov cov hlau mus rau qhov kub thiab txias sai sai hauv qhov nruab nrab quenching xws li dej los yog roj. Qhov txias txias no ua rau cov hlau tawv. Tom qab ntawd tempering yog ua los txo cov brittleness ntawm quenched steel thiab txhim kho nws toughness. Kev kho cua sov tsis zoo, xws li kub thiab sijhawm, yuav tsum tau ua tib zoo tswj kom ua tiav cov khoom xav tau.
Daim ntawv thov
SNCM815 steel yog dav siv nyob rau hauv ntau yam lag luam vim nws cov khoom zoo heev. Hauv kev lag luam tsheb, SNCM815 steel yog siv rau kev tsim khoom xws li iav, ncej, thiab crankshafts. Cov khoom no yuav tsum muaj lub zog siab thiab ua haujlwm ntev kom tiv taus cov kev ntxhov siab thiab lub zog tsim los ntawm lub cav. SNCM815 steel kuj tseem siv rau hauv kev lag luam tshuab rau kev tsim tshuab xws li bolts, ceev, thiab bearings. Hauv kev lag luam roj thiab roj, SNCM815 steel yog siv rau kev tsim cov laum dab tshos, tubing, thiab casing. Cov Cheebtsam no yuav tsum muaj kev tiv thaiv corrosion zoo thiab lub zog tiv taus qhov hnyav ib puag ncig ntawm kev tshawb nrhiav roj thiab roj thiab kev tsim khoom.
Qhov zoo
SNCM815 steel muaj ntau qhov zoo dua lwm hom hlau. Ib qho ntawm cov txiaj ntsig tseem ceeb yog nws lub zog siab thiab toughness. Qhov no ua rau nws haum rau cov ntawv thov uas cov khoom yuav tsum tau tiv taus hnyav thiab cuam tshuam. Lwm qhov zoo dua yog nws hnav tsis kam thiab corrosion kuj. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas cov khoom raug cuam tshuam rau qhov chaw abrasive thiab corrosive. Tsis tas li ntawd, SNCM815 steel yog ib qho yooj yim rau tshuab thiab vuam, ua rau nws yooj yim rau kev tsim thiab fabrication.
Xaus
Hauv kev xaus, SNCM815 steel yog ib hom hlau alloy uas muaj cov khoom siv zoo heev thiab cov tshuaj muaj pes tsawg leeg. Nws yog dav siv nyob rau hauv ntau yam lag luam vim nws lub zog siab, toughness, hnav tsis kam, thiab corrosion kuj. Kev kho cua sov yog txheej txheem tseem ceeb rau SNCM815 steel los ua kom zoo dua nws cov khoom siv kho tshuab. Los ntawm kev ua tib zoo tswj cov txheej txheem kev kho cua sov, cov tuam ntxhab tuaj yeem ua tiav cov khoom siv kho tshuab uas xav tau rau cov ntawv thov tshwj xeeb. SNCM815 steel yog cov khoom tseem ceeb rau ntau daim ntawv thov thiab tseem yuav yog ib feem tseem ceeb ntawm kev lag luam steel.
