Khoom Description
JIS SKS7 roj-hardening txias ua hauj lwm cuab yeej steel yog ib tug zoo kawg li cov khoom uas muaj ib tug tshwj xeeb ua ke ntawm cov khoom, ua rau nws heev nrhiav tom qab nyob rau hauv ntau yam kev lag luam daim ntaub ntawv. Cov hlau no paub txog nws qhov tshwj xeeb hardness, toughness, thiab hnav tsis kam, uas ua rau nws tuaj yeem tiv taus qhov kev xav tau ntawm kev tsim khoom.
Cov yam ntxwv roj-hardening ntawm JIS SKS7 steel muab ntau qhov zoo. Thaum quenched nyob rau hauv cov roj, cov hlau tau dhau los ua cov txheej txheem txias sai uas ua rau muaj qhov zoo-grained microstructure nrog siab hardness. Cov txheej txheem hardening no imparts zoo heev hnav tsis kam, tso cai rau cov hlau tuav nws cov ntug ntse thiab tiv thaiv puas txawm tias siv hnyav.

JIS SKS7 roj-hardening txias ua hauj lwm cuab yeej steel kuj paub txog nws zoo machinability. Nws tuaj yeem ua tau yooj yim machined siv cov pa machining txoj kev, txawm hais tias cov cuab yeej tsim nyog thiab cov txheej txheem yuav tsum tau vim nws hardness. Qhov no ua rau nws yooj yim rau cov neeg tsim khoom los tsim cov cuab yeej siv cov cuab yeej siv nrog siab precision.
Cov tshuaj muaj pes tsawg leeg ntawm JIS SKS7 steel yog ua tib zoo sib npaug kom ua tiav nws cov khoom xav tau. Nws feem ntau muaj kev sib xyaw ua ke ntawm carbon, chromium, tungsten, thiab vanadium, ntawm lwm yam. Cov khoom no ua rau cov hlau hardness, hnav tsis kam, thiab toughness.
