Cov Khoom Kub Kub Ua Haujlwm Hlau 1.2888 Cov Khoom Siv Tshuaj
Hom: Phaj / Round bar / Pav ca bar
Tus me nyuam lub sij hawm: Annealed dub nto / Tig kaj nto
Khoom Description
1.2888 High-temperature thiab high-speed tuag steel, uas muaj lub zog siab, kub tsis kam thiab hnav tsis kam. 1.2888 High-temperature thiab high-speed tuag steel yog tsuas yog siv rau lub taub hau lub taub hau, nozzle lub cev, infusion raj, thiab lwm yam ntawm txhuas tuag-casting, magnesium alloy, tooj liab tuag-casting pwm.Extreme tuav ntawm hardness, haum rau txhua daim ntawv thov nyob qhov twg. tshwj xeeb tsis kam rau kub hnav thiab yaj ntawm hlau yog yuav tsum tau.
Kev kho cua sov
1.2888 Quenching kub: 1100-1150 degree Common tempering kub: 600-750 degree Tempering hardening tus nqi / MPa 500 degree - 55 600 - 54 650 - 53 (nto hardness tom qab deg hardening)
Lub cev muaj zog (qhov nruab nrab qhov tseem ceeb) ntawm qhov kub thiab txias
Modulus ntawm elasticity [103 x N/mm2]: 215
Qhov ceev [g/cm3]: 8.08
Mos Annealing
Tshav kub rau 760-840 degree, txias maj mam hauv qhov cub. Lub sijhawm yog 4-6 teev. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 320.
Kev ntxhov siab
Kev ntxhov siab kom tshem tawm cov kev ntxhov siab yuav tsum tau ua los ntawm cua sov mus rau 600-650 degree, tuav rau 1-2 teev thaum tshav kub, ua raws li cua txias. Qhov kev ua haujlwm no yog ua los txo qis kev sib txawv thaum kho cua sov.
Hardening
Harden los ntawm qhov kub ntawm 1100-1150 degree tom qab cua, roj quenching los yog nqus quenching. Hardness tom qab quenching yog hais txog 52 HRC.
