DIN 1.2419 Cov Cuab Yeej Ua Haujlwm Txias Hlau Bar
Hom: Round bar
Lub sij hawm xa tuaj: Annealed dub nto / Tig ci nto / Q ntxiv T
Khoom Description
1.2419 steel yog cov feem ntau siv siab carbon alloy cuab yeej steel rau pwm ua.1.2419 steel muaj siab hardenability. Raws li tungsten cov ntaub ntawv tungsten carbide, cov hlau no muaj ntau tshaj carbide, siab hardness thiab hnav tsis kam tshaj chromium steel thiab 1.2607 Steel. Tsis tas li ntawd, tungsten kuj tseem pab khaws cov nplej zoo, uas ua rau cov hlau tau zoo dua toughness. Yog li ntawd, cov cuab yeej txiav ua los ntawm CrWMn steel muaj tsawg dua qhov tshwm sim ntawm ntug thiab tuaj yeem tswj tau qhov zoo thiab qhov loj ntawm ntug.
1.2419 Steel Thaum tshav kub kub kho
1.2419 Steel Yam ntxwv:
1.2419 steel yog siv dav siv dav hauv kev ua haujlwm txias tuag steel, hu ua "tsis hloov pauv steel", tab sis nws yog rhiab heev rau kev tsim cov carbides network. Nws yog tsuas yog siv rau kev txiav cov cuab yeej (xws li broaches, ntev kais, ntev reamers, tshwj xeeb milling cutters) thiab ntsuas cov cuab yeej (xws li tuag, thaiv gauges, gauges, qauv kab, qauv tes tsho) nrog me deformation thiab complex zoo thaum quenching, as well as high-precision txias stamping tuag nrog seem me me thiab cov duab nyuaj.

Mos Annealing
Tshav kub rau 1050-850 degree, txias maj mam hauv qhov cub. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 230.
Kev ntxhov siab
Kev ntxhov siab kom tshem tawm cov kev ntxhov siab yuav tsum tau ua los ntawm cua sov kom txog li 750 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 1050-850 degree tom qab los ntawm roj quenching los yog sov da dej quenching 150-250 degree . Hardness tom qab quenching yog 64 HRC.
