20 # Seamless Precision Yeeb Nkab
20 # precision steel yeeb nkab
20 # precision steel yeeb nkabyog cov khoom siv high-precision steel yeeb nkab ua tiav los ntawm kev kos duab txias lossis kub dov. Txij li thaum 20 # precision carbon steel yeeb nkab tsis muaj oxide txheej ntawm sab hauv thiab sab nrauv phab ntsa, tuaj yeem tiv taus siab yam tsis muaj qhov to, muaj qhov siab, siab smoothness, tsis deformation hauv txias dabtsi yog khoov, tsis muaj kab nrib pleb thiab flattening, thiab lwm yam. yog siv los tsim cov khoom rau pneumatic lossis hydraulic Cheebtsam. Xws li lub tog raj kheej lossis cov roj kheej kheej, uas tuaj yeem yog cov kav dej seamless lossis welded kav. Cov tshuaj muaj pes tsawg leeg ntawm precision steel kav yog carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, thiab chromium Cr.
Cov khoom tseem ceeb ntawm 20 # Precision ci seamless steel yeeb nkab yog seamless steel yeeb nkab, uas yog tsim los ntawm txias txias los yog txias dov txheej txheem. Nws sab hauv thiab sab nrauv yog du, nrog qhov siab qhov tseeb thiab cov phab ntsa tuab, uas tuaj yeem ua tau raws li ntau yam kev xav tau. Nyob rau tib lub sijhawm, 20 # High precision seamless steel yeeb nkab muaj cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab zoo, thiab tuaj yeem tiv taus siab dua thiab cuam tshuam.
20 # Txias kos precision seamless steel yeeb nkab feem ntau yog siv los tsim cov cuab yeej ntsuas siab thiab cov khoom siv tshuab. Vim nws qhov siab qhov tseeb thiab du nto, nws tuaj yeem ua kom ruaj khov thiab raug ntawm cov khoom siv. Piv txwv li, hauv kev lag luam tsheb tsim, 20 # Seamless Precision Yeeb Nkab feem ntau yog siv los tsim cov cav thiab chassis Cheebtsam txhawm rau txhim kho tsheb kev ua haujlwm thiab kev ntseeg tau.

High precision seamless steel yeeb nkab
Raws li qhov kev ua tau zoo sib txawv ntawm 20 # precision steel yeeb nkab thiab nws qhov sib txawv tempering kub, tempering tuaj yeem muab faib ua hom hauv qab no:
(1) Tsawg kub tempering (150-250 degrees)
Cov qauv tau los ntawm qhov kub thiab txias yog tempered martensite. Lub hom phiaj yog los txo cov quenching sab hauv kev ntxhov siab thiab brittleness ntawm quenched 20 # precision steel yeeb nkab thaum tuav nws siab hardness thiab siab hnav tsis kam kom tsis txhob tawg los yog puas thaum ntxov thaum siv. Nws yog tsuas yog siv rau ntau yam high-carbon txiav cov cuab yeej, ntsuas cov cuab yeej, txias stamping tuag, dov bearings thiab carburized qhov chaw, thiab lwm yam. Lub hardness tom qab tempering feem ntau yog HRC58-64.
(2) Nruab nrab kub tempering (250-500 degrees)
Cov qauv tau los ntawm tempering ntawm nruab nrab kub yog tempered troostite. Lub hom phiaj yog kom tau txais cov txiaj ntsig siab, kev txwv elastic thiab siab toughness ntawm 20 # precision steel yeeb nkab. Yog li ntawd, nws yog tsuas yog siv rau kev kho mob ntawm ntau yam springs thiab kub ua hauj lwm pwm. Lub hardness tom qab tempering feem ntau yog HRC35-50.
