60Si2Mn kub dov steel puag ncig tuav

60Si2Mn caij nplooj ntoos hlav steel yog siv dav siv silico-manganese caij nplooj ntoos hlav steel nrog me ntsis siab zog, elasticity thiab hardenability tshaj 55Si2Mn. 60Si2Mn caij nplooj ntoos hlav steel kev lag luam tsim cov springs tiaj tus nrog cov load loj lossis coil springs nrog txoj kab uas hla tsawg dua 30mm. Nws kuj tseem tsim nyog rau kev ua kom sov-resistant springs nrog tsis-corrosive nruab nrab nrog kev ua hauj lwm kub hauv qab 250 ° C thiab nrog alternating load thiab siab zog. Loj loj coil springs rau kev ua hauj lwm hauv qab, nrog rau cov tsheb poob siab absorbing tshuab.

Txoj kev kho cua sov

60Si2Mn txoj kev kho cua sov yog isothermal tempering thiab grading quenching, sub-temperature quenching thiab high temperature tempering, deformation heat treatment process. Txoj kev tuaj yeem txhim kho lub zog thiab kev pabcuam lub neej ntawm 60Si2Mn caij nplooj ntoos hlav steel. 60Si2Mn belongs rau lub caij nplooj ntoos hlav steel, haum rau ua lub caij nplooj ntoos hlav tsheb. 60Si2Mn caij nplooj ntoos hlav steel tshav kub kho isothermal tempering thiab grading quenching, sub-temperature quenching thiab kub tempering, deformation kub kho txheej txheem. Txoj kev tuaj yeem txhim kho lub zog thiab kev pabcuam lub neej ntawm 60Si2Mn caij nplooj ntoos hlav steel.

ceev

60Si2Mn ceev ntawm 7.85g / / cm3. 60Si2Mn yog dav siv silicon manganese caij nplooj ntoos hlav steel, lub zog, elasticity thiab hardenability tshaj 55Si2Mn me ntsis siab dua. Haum rau cov tsheb ciav hlau, tsheb laij teb kev lag luam los tsim cov khoom loj dua ntawm cov tiaj tiaj tiaj lossis hlau txoj kab uas hla ntawm 30mm hauv qab lub caij nplooj ntoos hlav coil.
