 Low-alloy heat-resistant steel, muaj zog tshaj 12CrMo steel, toughness qis me ntsis, ntawm 500-550 ° C los yog tsawg dua muaj cua sov ua hauj thiab oxidation tsis kam, thiab zoo mechanical zog, machinability thiab txias strain plasticity zoo. weldability ncaj ncees. Feem ntau yog siv rau kev tsim ntau yam caliber seamless steel yeeb nkab thiab ntawv.



15CrMo Daim ntaub ntawv:



 Cov yeeb nkab tseem ceeb rau chav ntsuas ntawm 510 ° C, 530 ° C chav tsis muaj boiler superheater hlab, catheters thiab high-pressure chav header, tom qab quenching thiab tempering, nyob rau hauv chav tsev kub yuav siv tau los tsim ntau yam tseem ceeb ntawm kev ua hauj lwm.

Kev kho cua sov yog qhov ntsuas tau zoo heev los txhim kho thiab hloov kho cov khoom ntawm 15CrMo alloy round steel. Nws plays lub luag haujlwm tseem ceeb hauv cov khoom lag luam kev ntseeg siab thiab kev lag luam. Kev kho cua sov ntawm 15CrMo alloy round steel feem ntau suav nrog kev kho cua sov zoo tib yam (annealing, normalizing, quenching, tempering) thiab kev kho cua sov saum npoo (nto quenching thiab tshuaj kho cua sov - carburizing, nitriding, metalizing, thiab lwm yam).

Hauv kev tsim kho tshuab, ntau yam tshuab, xws li crankshafts, lub zog, camshafts ntawm cov cav sib xyaw ua ke, thiab cov iav hauv cov khoom tseem ceeb, tsis yog tsuas yog xav tau kom muaj zog txaus, plasticity thiab dabtsi yog khoov lub zog hauv cov tub ntxhais, tab sis kuj yuav tsum muaj qhov siab ntawm qhov tuab hauv ib qho thickness. . Hardness, siab hnav tsis kam thiab siab qaug zog. Cov lus hais saum toj no ntau yam kev kho cua sov tag nrho yog qhov nyuaj kom ua tau raws li cov kev xav tau saum toj no nyob rau tib lub sijhawm, thiab kev siv cov kev kho cua sov saum npoo yog txoj hauv kev zoo tshaj plaws kom ua tiav cov kev ua tau zoo ntawm tib lub sijhawm.

Kev kho cua sov saum npoo yog ib txoj kev kho cua sov uas hloov cov khoom nto ntawm 15CrMo alloy round steel los ntawm kev hloov cov qauv ntawm txheej txheej.
Surface quenching yog kev kho cua sov uas hloov cov qauv saum npoo ib los ntawm ib qho tsis hloov cov tshuaj lom neeg ntawm qhov chaw. Nws tuaj yeem pom tau los ntawm qhov siab zaus, nruab nrab zaus lossis lub zog zaus tam sim no induction cua sov txoj kev lossis nplaim hluav taws kub txoj kev. Qhov zoo tshaj plaws yog qhov saum npoo ntawm 15CrMo alloy puag ncig steel yog nrawm nrawm rau qhov kub thiab txias, thiab thaum tshav kub tsis hloov mus rau qhov tseem ceeb ntawm qhov, nws yuav txias sai sai, yog li ntawd lub hardness ntawm qhov saum npoo yog siab, tab sis qhov kub thiab txias tsis hloov mus rau qhov tseem ceeb ntawm qhov chaw, nws yuav tsum tau txias sai sai. core tseem muaj siab toughness.

Kev kho tshuaj yog ib txoj kev kho cua sov uas hloov cov tshuaj muaj pes tsawg leeg thiab cov qauv ntawm txheej txheej ntawm 15CrMo alloy round steel. Kev kho cua sov tuaj yeem muab faib ua cov txheej txheem xws li carburizing, nitriding, carbonitriding, thiab metalizing raws li cov ntsiab lus sib txawv infiltrated rau saum npoo ntawm 15CrMo alloy round steel. Nws yog qhov zoo heev rau kev txhim kho thiab txhim kho cov hnav tsis kam, corrosion kuj thiab qaug zog tsis kam ntawm 15CrMo alloy round steel. Tam sim no, tshuaj kho cua sov tau tsim sai heev, thiab muaj ntau yam kev siv thev naus laus zis tshiab.
