Forged ntawm M35 Hlau Hlau Khoom

Thaum xub thawj, Pre-Heating rau 650-750 degree, Tom qab ntawd kub rau forged kub.

Tom ntej no, Soak ntawm 1050-1100 degree, xyuas kom sov kom huv si.

Tom qab ntawd pib forged, qhov forged kub tsis qis dua 950 degree.

Tom qab forging, txias maj mam.

M35 HSS Steel Annealing

Thaum xub thawj, maj mam cua sov mus rau 871 degree, ces maj mam Txias mus rau 538 degree (1000℉) hauv qhov cub kho cua sov.

Tom qab ntawd txias hauv huab cua. Tom qab annealing, hardness HBS: 269 Max.

M35 cuab yeej Steel Hardening

M35 steel muaj hardenability heev thiab yuav tsum tau hardened los ntawm txias nyob rau hauv tseem huab cua. Kev siv cov ntsev da dej los yog lub qhov cub hluav taws xob tswj tau yog qhov tsim nyog kom txo qis decarburization, thiab yog tias tsis muaj, pob tawv tawv hauv cov suab coke tau pom zoo.

Daim ntawv thov

M35 kev kub ceev steel yog lub ntsiab feature uas muaj Co general tej cuab yeej steel, quenching hardness yog 1200-1240 c. Tsis tas li ntawd, M2 tau siv rau hauv cutter, broach, kawg milling cutter. Rau kev tsim muaj zog txiav nrog hnav-resistant, resistant rau feem ntau yam cuab yeej, advanced xuas nrig ntaus tuag, ntsia hlau tuag, lub toughness thiab complex cov cuab yeej, reamer, milling cutter, bunt, punch, thiab lwm yam

M35 cov cuab yeej hlau feem ntau yog siv rau hauv cov xwm txheej uas qhov kev thov rau qhov kub hardness siab, xws li cov cuab yeej txiav nrog rau broaches, milling cutters, reamers, kawg mills thiab saw hniav. Nws kuj yog ib qho zoo hnav resistant qib HSS rau qhov chaw ua haujlwm txias.
