20CrNiMo (8620H) kub dov steel puag ncig tuav

GB 20CrNiMo alloy hlau yog qhov zoo tshaj plaws Quenched thiab Tempered Alloy Cov Khoom Siv Hluav Taws Xob, thiab nws yog cov khoom zoo uas tsis muaj cov pa roj carbon tsawg, tsis tshua muaj chromium, molybdenum, nickel rooj plaub hardening hlau. Roj quenched & Tempered Hardenss yog 28-34 HRC. GB 20CrNiMo steel Annealing xa khoom hardenss tsawg dua 250HB.

GB 20CrNiMo Alloy structural steel zog yog ib tug Nickel chromium molybdenum alloy steel specification. 20CrNiMo Nrog cov ntsiab lus qis dua, Yog li GB 20CrNiMo steel muaj qhov zoo weldability.

Daim ntawv thov

GB 20CrNiMo steel yog dav siv rau ntau yam kev siv hauv kev siv hauv tsheb thiab engineering kev lag luam rau cov cuab yeej thiab lwm yam khoom siv. Cov kev siv xws li lub cev valve, twj thiab fittings, Ncej, lub siab load ntawm lub log, bolts, ob lub taub hau bolts, zog, thiab lwm yam

Kev kho cua sov ntsig txog

• Annealing ntawm 20CrNiMo Alloy cov qauv hlau

Maj mam rhuab mus rau 850 ℃ thiab cia lub sij hawm txaus, cia cov hlau kom huv si, ces txias maj mam nyob rau hauv lub cub tawg. 20CrNiMo alloy hlau yuav tau MAX 250 HB (Brinell hardness).

• Hardening ntawm 20CrNiMo Alloy qauv steel

Tshav kub maj mam mus rau 880-920 ° C, Tom qab txaus soaking ntawm no kub quench nyob rau hauv cov roj. Kub kom sai li sai tau thaum cov cuab yeej ncav cuag chav sov.
