6150 Caij nplooj ntoos hlav Steel Hlau Qws

6150 steel yog lub caij nplooj ntoos hlav siab tshaj plaws siv rau kev thauj khoom tseem ceeb nrog cov hlaws loj dua, nrog rau lub valve springs, piston springs, thiab kev nyab xeeb valve springs nrog kev ua haujlwm kub.<300 ℃.

6150 steel muaj cov cuab yeej zoo thiab thev naus laus zis, muaj zog hardenability, thiab qhov sib ntxiv ntawm vanadium refines cov nplej loj ntawm cov hlau, txo cov cua sov rhiab heev, txhim kho lub zog thiab toughness, thiab muaj zog qaug zog thiab tawm los piv. Txawm li cas los xij, nws muaj qhov tsis zoo weldability thiab qis txias deformation plasticity.

Chemical Composition (%)

Kev kho cua sov:
· FORGING: Preheat kom zoo zoo, ces nce kub rau 1050 degree forging. Tsis txhob forge hauv qab 840 degree. Tom qab forging txias maj mam nyob rau hauv ib lub qhov cub.
· ANNEALING: Tshav kub maj mam mus rau 820-840 degree, tsau kom zoo thiab maj mam txias hauv qhov cub.
· HARDENING: Tshav kub maj mam mus rau 650-700 degree thiab so kom huv si. Txuas ntxiv kom sov lub 6150 steel mus rau qhov kawg hardening kub ntawm 830-860 degree thiab tso cai rau kom sov los ntawm. Roj quench.
· TEMPERING: Temper 6150 caij nplooj ntoos hlav steel tam sim ntawd tom qab hardening whilst cov cuab yeej tseem sov tes. Rov ua kom sov rau qhov kub thiab txias tom qab ntawd tsau rau ib teev rau 25 millimeter ntawm tag nrho cov tuab (2 teev yam tsawg kawg nkaus) Txias hauv huab cua. Tempering ntawm qib no yuav nyob nruab nrab ntawm 400-600 degree rau feem ntau daim ntawv thov.
