GB 3Cr2MnNiMo DIN 1.2738 AISI P20 ntxiv rau Ni / 718 Mould Steel Bar
1: TIAB SA 1.2738steel kev taw qhia
DIN 1.2738 tshwj xeeb yog siv rau cov yas txhaj tshuaj tuag pwm. Cov yam ntxwv ntawm cov khoom yog txoj cai sharpening, yees duab-etching zog nrog siab purity thiab zoo homogeneity. DIN 1.2738 yog upgraded version ntawm yas pwm steel 0f 1.2311, uas ib txwm muab nyob rau hauv Pre hardened mob. Hardness nyob rau hauv raws li qhov chaw muab khoom 280-320 HB nrog muaj ib yam nyuaj hardness. Cov ntsiab lus npib tsib xee ntxiv ntawm 1 feem pua nce los ntawm hardening. Nws muaj zoo machinability, haum rau Texturing, zoo polishability, txaus corrosion kuj, nqus-degassed steel.
