Alloy Steel 1.2738 718H Hlau
CLC 1.2738 yog 300HB (30HRC) qib pre-hardened tshwj xeeb uas tsim los rau kev lag luam pwm yas. Chromium, Molybdenum, Nickel carbon thiab manganese ntxiv yog optimized kom muaj tag nrho martensite-bainite microstructure tom qab quenching. Cov ntsiab lus siab nickel (1%) tshwj xeeb yog hloov kho kom ntseeg tau tias muaj kev sib haum xeeb ntawm cov qauv thiab hardness los ntawm thickness txawm tias cov blocks tuab heev (txog 700mm / 28"). Cov hlau yog melted nyob rau hauv hluav taws xob rauv thiab refined nrog VOD los yog DH ntaus ntawv Qhov kev huv ntawm cov hlau yog guaranteed raws li zoo raws li lub suab. Qhov no ua rau cov hlau tshwj xeeb zoo yoog rau pwm txawm tias polishing lossis tshuaj etching yuav tsum tau ua kom tiav qhov zoo.
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 2738 yog upgraded version ntawm yas pwm steel 0f 2311, uas ib txwm muab nyob rau hauv Pre hardened mob. Hardness nyob rau hauv raws li cov kev mob 280-320 HB nrog muaj ib yam nyuaj hardness. Cov ntsiab lus nickel ntxiv ntawm 1% nce los ntawm hardening. Nws muaj zoo machinability, haum rau Texturing, zoo polishability, txaus corrosion kuj, nqus-degassed steel.
