Precisionseamless yeeb nkab hardness thiab hardness hloov tom qab kev kho cua sov Precision seamless yeeb nkab yog high-zoo carbon structural steel, uas tsis siab hardness thiab yooj yim rau machined.Nws yog feem ntau siv hauv pwm ua cov qauv, cov lus qhia, cov lus qhia, thiab lwm yam, tab sis yuav tsum tau kho cua sov.

No. 45 steel yuav tsum tsis txhob raug kho los ntawm carburizing thiab quenching.Tom qab quenched thiab tempered qhov chaw muaj kev zoo txhua yam khoom, lawv tau dav siv nyob rau hauv ntau yam tseem ceeb yam ntxwv qhov chaw, tshwj xeeb tshaj yog cov txuas rods, bolts, gears uas ua hauj lwm nyob rau hauv alternating loads, tab sis lub deg hardness yog tsawg, thiab lawv tsis hnav-resistant.quenching thiab tempering tuaj yeem siv los txhim kho qhov nyuaj ntawm qhov chaw.

Carburizing kev kho mob feem ntau yog siv rau cov khoom hnyav uas muaj qhov hnav tsis kam thiab cov ntsiab lus cuam tshuam, thiab nws cov hnav tsis kam yog siab dua li ntawm quenching thiab tempering.Yog tias carburizing nrog 45 # steel, tawv thiab nkig martensite yuav tshwm sim hauv cov tub ntxhais tom qab quenching, poob qhov zoo ntawm kev kho carburizing.Cov ntaub ntawv uas siv cov txheej txheem carburizing tam sim no muaj cov ntsiab lus carbon tsawg, uas tuaj yeem ncav cuag siab heev ntawm 0.30%, uas tsis tshua muaj nyob rau hauv daim ntawv thov.
