38CrMoAl Alloy Structure Steel (Nitride Steel) Round Bar DIN 1.8509 41CrAlMo7-10 Forged Steel Qws

38CrMoAl yog cov qauv hlau alloy uas muaj cov khoom siv aluminium siab, uas feem ntau yog siv tom qab quenching thiab nitriding.Tom qab nitriding, 38CrMoAl muaj qhov tawv tawv siab, hnav tsis kam thiab qaug zog, thiab muaj cov cua sov zoo thiab corrosion.

Cov yam ntxwv ntawm 38CrMoAl nitriding yog qhov ceev ceev thiab qhov tob ntawm nitriding txheej tuaj yeem tau txais. Txawm li cas los xij, lub brittleness ntawm nitriding txheej yog qhov loj, yog li nws tsis haum rau kev ua cov khoom uas muaj kev cuam tshuam loj heev.

THOV KEV PAB CUAM

Cov txheej txheem ntws ntawm nitriding feem ntau yog: forging → normalizing (annealing) → ntxhib machining → tempering thiab tempering → tiav machining → de-stress → nplua sib tsoo → nitriding → nplua sib tsoo → sib dhos.

Lub hom phiaj ntawm 38CrMoAl nitriding kev kho mob yog tsuas yog rau hnav tsis kam.Tom qab nitriding, nws hardness yog siab li HV800, txheej hardened yuav ncav cuag 0.30mm ~ 0.5mm.

APPLICATION

38CrMoAl feem ntau yog siv rau hauv kev tsim cov khoom uas muaj qhov loj me, xav tau kev hnav tsis kam thiab qaug zog, thiab tsis raug rau kev cuam tshuam loj, xws li lub tog raj kheej liner, lub tes tsho hauv qab, iav, bolts, ncej thiab rotor, thiab lwm yam.

Tsis tas li ntawd, vim tias AL thiab CR thiab ua cov yeeb nkab uas tsis tshua muaj zog ntawm cov kav dej roj thiab dej hiav txwv uas muaj cov nruab nrab hauv cov chaw tsim hluav taws xob hauv ntug dej hiav txwv, cov chaw cog roj hauv hiav txwv, cov roj av hauv hiav txwv thiab cov nroj tsuag petrochemical.
