Qhov Zoo ntawm EN 10297-1 Seamless Alloy Neeg Kho Tshuab Tube

 

Cov txheej txheem tshwj xeeb no sib piv thiab cov txheej txheem ntau lawm muab cov kav hlau sib txuas tshwj xeeb:

 Siab zog thiab kev sib npaug sib npaug

Alloy Ntsiab (xws li MN, CR, C) txhim kho tensile lub zog thiab tawm los ntawm lub zog, piv txwv:
A). E355 qib steel: Yam tsawg kawg tensile lub zog ntau dua los yog sib npaug rau 490 mpa, tawm kom muaj zog dua lossis sib npaug rau 355 mpa
B). E470 Qib Hlau: Ntxiv rau Vanadium (V: 0.05-0.15%) thiab niobium (nb), tensile lub zog ntau dua lossis sib npaug, haum rau kev cuam tshuam kev tsim chaw.
Qhov txheej txheem seamam kom tshem tawm thaj chaw tsis muaj zog ntawm Weld, ua kom cov qauv sib txawv ntawm cov qauv txheej txheem, thiab txo qhov kev pheej hmoo ntawm kev muaj kev ntxhov siab.

 

 ‌Kev ua tau zoo heev

Los kho cov ntsiab lus carbon (xws li 0.42-0.50% C ntawm C45E tau ua kom zoo dua los txhawb kev ua kom muaj kev ua raws li txoj kev tig thiab tho.
Qee qib (xws li 38mn6) tuaj yeem txhim kho cov npoo tawv thiab hnav tsis kam los ntawm quenching + tempering.

 

 Corrosion tsis kam thiab kub kuj tsis kam

Alloy ntsiab xws li chromium (CR) thiab Molybdenum (mo) Txhim kho cov tshuaj lom neeg uas tau muaj tshuaj lom neeg ib puag ncig lossis ib qho nruab nrab kub (tsawg dua lossis sib npaug nrog 400 degree).
