Daim ntawv thov:
Lub alloy seamless yeeb nkab yog ib hom seamless steel yeeb nkab, thiab nws cov kev ua tau zoo yog ntau dua li qhov zoo tib yam
seamless steel yeeb nkab. Vim tias cov yeeb nkab steel muaj ntau dua Cr, nws qhov kub thiab txias tsis kam, tsis kub tsis kam
thiab corrosion kuj zoo dua lwm yam seamless steel kav. Yog li cov hlau alloy raj siv dav hauv roj av, tshuaj,
hluav taws xob fais fab, boiler thiab lwm yam kev lag luam.
4140 tuab-walled seamless yeeb nkab yog ultra-siab zog steel nrog siab zog thiab toughness, zoo hardenability, tsis pom tseeb
temper brittleness, siab qaug zog txwv thiab tsis kam mus rau ntau yam cuam tshuam tom qab quenching thiab tempering, tsis kub zoo
cuam tshuam toughness. Cov hlau yog tsim rau kev tsim cov yas pwm loj thiab nruab nrab uas xav tau ib lub zog
thiab toughness.
4140 tuab-walled seamless yeeb nkab yam ntxwv thiab Scope ntawm daim ntawv thov: siab zog, siab hardenability, zoo toughness, me me
deformation thaum lub sij hawm quenching, siab creep zog thiab ntev lub zog nyob rau hauv high kub. Forgings xav tau siab dua
lub zog thiab loj quenching seem tshaj 35CrMo steel, xws li lub zog loj rau locomotive traction, supercharger kis tau tus mob
iav, rear qag, loaded heev loaded rods thiab caij nplooj ntoos hlav clips, kuj yuav siv tau roj sib sib zog nqus zoo laum yeeb nkab pob qij txha thiab nuv ntses
cov cuab yeej hauv qab 2000m, thiab tuaj yeem siv rau pwm ntawm cov tshuab dabtsi yog khoov, thiab lwm yam.

Qhov zoo:
Cov khoom siv raw yog los ntawm Sab saum toj tsim khoom uas cog lus rau qhov zoo.
Cov thev naus laus zis raug lees paub qhov tseeb qhov ntev ntev.
Pab neeg muag khoom tau zoo muab cov lus pom zoo rau koj.
Pab neeg tom qab muag muab thiab kev txhawb nqa rau cov khoom lav.
Kev Tswj Xyuas Zoo:

A: Peb tuaj yeem muab kev txiav, drilling, pleev xim, tsho tiv no hmoov thiab lwm yam ...
Q4: Koj qhov zoo ntawm cov hlau yog dab tsi?
A: Peb tuaj yeem kho cov qauv steel raws li kev yuav cov duab kos lossis thov.
Q5: Yuav ua li cas txog koj qhov kev pabcuam logistic?
A: Peb muaj cov kws tshaj lij kev lag luam uas muaj kev paub dhau los ntawm kev xa khoom, tuaj yeem muab cov nkoj ruaj khov thiab zoo.
Kev ua lag luam:
Peb tau tsim lub sijhawm ntev thiab ruaj khov kev sib raug zoo nrog cov neeg siv khoom hauv tsev, xws li Shanghai, Jiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan thiab lwm yam.
Rau txawv teb chaws, peb cov neeg siv khoom tseem ceeb los ntawm South Asia, Africa, South America xws li Singapore, Nyab Laj, Brazil, Ghana, New Zealand,
Spain, Mauritius, Dubai thiab lwm yam.
