Nyob rau hauv cov nqe lus ntawm hardness, SUS 440C steel muaj ib tug kuj siab Rockwell hardness, uas ua rau nws haum rau daim ntaub ntawv uas durability thiab kuj rau abrasion tseem ceeb heev. Cov cuab yeej hardness no ua rau nws tiv taus kev siv hnyav thiab tswj nws txoj kev ncaj ncees nyob rau lub sijhawm.
Hais txog kev hnav tsis kam, nws ua tau zoo dua lwm yam steels. Nws tuaj yeem tiv taus qhov hnav thiab tsim kua muag tshwm sim los ntawm kev sib txhuam thiab kev ntxhov siab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas yuav raug rov ua dua los yog tiv tauj. Cov yam ntxwv no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov khoom siv, xws li bearings thiab gears, qhov kev txo qis yog qhov tseem ceeb rau kev ua haujlwm zoo thiab kev ua haujlwm ntev.
Corrosion kuj yog lwm qhov zoo ntawm SUS 440C steel. Nws tuaj yeem tiv taus cov teebmeem corrosive ntawm ntau qhov chaw, nrog rau cov dej noo, tshuaj lom neeg, thiab qee yam acidic. Cov cuab yeej no ua rau nws tsim nyog siv rau hauv cov ntawv thov uas raug mob hnyav, xws li hauv kev lag luam marine lossis hauv cov chaw ua tshuaj.
Kev tsim cov txheej txheem ntawm SUS 440C steel koom nrog kev ua tib zoo alloying thiab kev kho cua sov kom ua tiav cov khoom xav tau. Cov muaj pes tsawg leeg thiab kev kho mob kom ntseeg tau tias cov hlau muaj qhov sib npaug ntawm lub zog, hardness, thiab toughness.
Ntxiv nrog rau nws cov khoom siv kho tshuab, SUS 440C steel kuj muaj kev ua haujlwm zoo. Nws tuaj yeem ua tau yooj yim zoo li tus thiab ua tiav rau hauv cov ntaub ntawv sib txawv thiab qhov ntau thiab tsawg, tso cai rau kev tsim cov khoom sib xyaw nrog kev ua haujlwm siab.
Zuag qhia tag nrho, SUS 440C steel yog cov khoom siv ntau yam thiab txhim khu kev qha uas muaj kev sib xyaw ua ke ntawm cov khoom tsim nyog. Nws hardness, hnav tsis kam, thiab corrosion kuj ua rau nws nyiam xaiv nyob rau hauv ntau yam engineering thiab manufacturing daim ntaub ntawv, pab txhawb rau kev ua tau zoo thiab durability ntawm ntau yam khoom thiab khoom siv. Txawm hais tias nws tau siv hauv kev tsim cov cuab yeej txiav, cov cuab yeej phais, lossis cov khoom siv tshuab ua haujlwm siab, SUS 440C steel tseem ua pov thawj nws tus nqi thiab qhov tseem ceeb hauv lub ntiaj teb kev lag luam.
