12CrMoV, 40CrMo4, thiab 42CrMo4 Alloy Steel Phaj

12CrMoV (Suav tus qauv), 40CrMo4 (European standard), thiab 42CrMo4 (European standard) yog tag nrhosiab -lub zog alloy structural steel daim hlaudav siv nyob rau hauv machinery manufacturing, engineering khoom, thiab siab -stress Cheebtsam. Lawv qhia cov yam ntxwv tseem ceeb zoo sib xws- zoo toughness, siab tensile zog, thiab zoo hardenability- thaum txawv me ntsis nyob rau hauv tshuaj muaj pes tsawg leeg thiab daim ntawv thov scenarios.

Cov txheej txheem kho cua sov

Kev kho cua sov yog qhov tseem ceeb rau kev txhim kho lawv cov khoom siv kho tshuab, ua kom haum rau txhua qib:

 

12 CrMoV:

normalizing: Kub rau 900-950 degree, tuav, ces cua txias kom ua kom cov nplej.

Tempering: Thaum tshav kub kub rau 650-750℃rau 2-4 teev kom txo tau brittleness thiab txhim kho toughness, haum rau high-temperature kev pab cuam.

40CrMo4/42CrMo4:

Quenching: Thaum tshav kub kub rau 820-860℃(austenitizing), tom qab ntawd dej los yog roj quenching kom tiav martensitic qauv, maximizing hardness.

Tempering: Thaum tshav kub kub rau 500-650℃(nyob ntawm qhov xav tau hardness) kom txo tau kev ntxhov siab thiab sib npaug zog / toughness. Piv txwv li, tempering ntawm 550℃ua tiav ~ 30 HRC nrog zoo heev toughness.

 

 

 

 

 

 

 

Machining yam ntxwv

Vim lawv lub zog siab thiab cov ntsiab lus alloy, machining yuav tsum tau ceev faj kev tswj xyuas:

 

Txiav: Siv siab - steel ceev (HSS) los yog cemented carbide cov cuab yeej. Rau 40CrMo4 / 42CrMo4, txo txiav ceev los ntawm 10-20% piv rau cov pa roj carbon steel kom tsis txhob hnav cov cuab yeej. Coolants (xws li, emulsion) yog qhov tseem ceeb los tiv thaiv overheating.

Drilling: Ua ntej- tho qhov me me tsav kom txo torque; siv coated xyaum (TiN lossis TiAlN) kom zoo dua hnav tsis kam.

Sib tsoo: Haum rau kev ua tiav kom ua tiav qhov siab tshaj plaws, nrog cov dej txias los tiv thaiv thermal puas.
