P275NH steel phaj

P275NH belongs rau lub boiler thiab siab hlab ntsha tshwj xeeb steel phaj, P275NH steel phaj siv tus qauv rau EN10028 tshwj xeeb kev mob.

P275NH steel phaj nws tus kheej muaj lub zog siab, siab toughness, qaug zog tsis kam, cuam tshuam tsis kam, hnav tsis kam, corrosion kuj, huab cua tsis kam, vuam thiab ua haujlwm yooj yim thiab lwm yam khoom zoo.

P275NH steel phaj feem ntau yog siv nyob rau hauv petrochemical thawv manufacturing kev lag luam

Piv txwv li; Lub taub hau, lub zog siab, lub nkoj siab, lub tshuab hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob sib hloov, cov kav dej siab, cov khoom siv petrochemical, cov cuab yeej siv tshuaj, cov khoom siv roj av, cov cuab yeej tiv thaiv ib puag ncig thiab lwm yam yog dav siv.

P275NH steel phaj vim nws muaj ntau yam kev ua tau zoo, nyob rau hauv cov txheej txheem ntawm kev siv cov kev ua tau zoo kuj tseem hlub thiab lees paub los ntawm kev tsim khoom lag luam, thiab tom qab ntawd vim muaj kev paub txog kev sib raug zoo, kev siv ntau zaus ntawm kev tsim khoom thiab cov chaw tsim khoom txuas ntxiv mus. txhawm rau txhim kho thiab txhim kho, maj mam P275NH steel phaj tau dhau los ua ib qho ntawm feem ntau siv steel phaj hom hauv Suav teb.

P275NH steel phaj tus me nyuam raws li txoj cai qhia

P275NH steel phaj yog xa hauv ib txwm muaj los ntawm lub neej ntawd

Raws li kev xav tau sib txawv tuaj yeem ua rau normalization, tempering, hloov kho thiab lwm yam txheej txheem kev xa khoom

P275NH steel phaj thickness soj ntsuam tuaj yeem yog '1 sojntsuam, 2 sojntsuam, 3 sojntsuam'

P275NH steel phaj thickness txuas ntxiv tuaj yeem ua 'z15, z25, z35' thaum tsim nyog.

Cov yam ntxwv ntawm kev ua haujlwm:

1. Cov khoom siv zoo heev: P275NH steel phaj muaj lub zog siab thiab tawv, lub zog tensile yam tsawg kawg nkaus tuaj yeem ncav cuag 370 mus rau 490 MPa, qhov tsawg kawg nkaus lub zog tuaj yeem ncav cuag 275 MPa, thiab qhov tsawg kawg nkaus elongation tuaj yeem ncav cuag 22%. Cov kev ua tau zoo no ua kom ntseeg tau tias cov phaj hlau tuaj yeem nyob ruaj khov nyob rau hauv qhov hnyav sab nraud thiab siab.

2, zoo corrosion kuj: P275NH steel phaj nyob rau hauv cov txheej txheem ntawm kev kho los tiv thaiv corrosion, muaj peev xwm tsim ib tug ntom oxide zaj duab xis nyob rau hauv lub corrosion ib puag ncig, zoo tiv thaiv kev nkag mus ntawm corrosive xov xwm, ncua kev pab cuam lub neej ntawm lub siab hlab ntsha.

3. Kev ua haujlwm vuam zoo: P275NH steel phaj muaj kev vuam zoo thiab yooj yim kom paub tsis siv neeg vuam. Hauv cov txheej txheem vuam, cov txheej txheem vuam tsim nyog thiab cov khoom siv vuam yuav tsum raug xaiv los xyuas kom meej qhov zoo ntawm vuam.
