Product Overview

ASTM A672 npog hluav taws xob- fusion-welded steel yeeb nkab haum rau siab - siab, siab - kub, thiab kev pabcuam dav dav. Qib B55 thiab B60 tshwj xeeb yog tsim los rau kev ua haujlwm siab, muab qhov zoo sib npaug ntawm lub zog, toughness, thiab weldability. Lawv tau siv dav hauv petrochemical, hluav taws xob tsim hluav taws xob, thiab cov kav dej muaj zog.

Ntsiab nta

Muaj peev xwm siab
Qib B55: yam tsawg kawg nkaus tawm lub zog 275 MPa (55 ksi)
Qib B60: yam tsawg kawg nkaus tawm lub zog 415 MPa (60 ksi)
Ob qib ua tau kev ntseeg siab nyob rau hauv kev kub siab, kub siab, thiab cyclic loading.

Electric Fusion Vuam (EFW)
The EFW process ensures a uniform, dense weld seam with high NDT pass rates, reducing risks of stress corrosion and fatigue cracking.

Tight Chemistry & Mechanical Control
Tsim nyob rau hauv nruj raws li ASTM A672 txwv ntawm C, Mn, P, S, thiab lwm yam. Tensile, khoov, thiab xaiv qhov kev ntsuam xyuas cuam tshuam lav kev nyab xeeb margins thoob plaws txhua qhov kev taw qhia.

Ntau qhov kev xaiv kho cua sov
Muaj raws li -welded, kev nyuaj siab-relieved, normalized, los yog normalized & tempered, cia cov neeg muas zaub xaiv qhov zoo tshaj plaws toughness, hardness, thiab residual stress profile.

Tau tshaj ntau Phaj Qib
Feem ntau tsim los ntawm A516 (los yog sib npaug) phaj lossis kauj, muab kev tiv thaiv zoo rau hydrogen nres thiab sulfide kev ntxhov siab tawg.
