Tus Thawj Coj Tsim Cov Nta ntawm DIN 30CrNiMo8 / 30CND8 Hlau
34CrNiMo6 yog ib qho ntawm feem ntau siv nag lossis daus hardening qib hauv kev lag luam. Thaum mos thiab ductile nyob rau hauv cov tshuaj annealed mob, nws muaj peev xwm ntawm high zog nrog ib tug los nag los yog kev laus kev kho mob. Cov yam ntxwv los ntawm kev ua haujlwm zoo corrosion, siab harness, toughness thiab lub zog.

Tshuab
TXOJ CAI A--So ntawm 1900 F (1038 C) rau 30 feeb thiab txias hauv qab 60 F (16 C) kom ua tiav kev hloov pauv martensite. CONDITION H 950- Kho mob A cov ntaub ntawv ntawm 900 F (482 C) rau 1 teev, cua txias.. CONDITION H925, H1025, H1075, H1100, H1150- Soak tov cov khoom kho rau 4 teev ntawm qhov teev qhov kub thiab txias, cua txias, CONDITION H1150M- Soak tov khoom kho ntawm 1400 F (760 C) rau 2 teev, cua txias, ces rov ua kom sov rau 1150 F (620 C) rau 4 teev thiab cua txias.
Vuam
Ua tiav welded los ntawm kev sib xyaw ua ke thiab kev ua haujlwm, cov hlau no yuav tsum tsis txhob koom nrog oxyacetylene vuam. AWS E/ER630 filler metal is recommend ifxav tau.
Forging
Soak rau 1 teev ntawm 2150 F (1177 C) ua ntej forging. Tsis txhob ua haujlwm qis dua 1850 F (1010 C). Kev kho tom qab ua haujlwm yuav tsum tau kho ua ntej qhov kawg hardening.
