EN 10025-6 S690QL vs S355 steel phaj

S690 qwyog lub siab - lub zog steel nrog qhov tsawg kawg nkaus yield zog ntawm690MPa, thaum S355 yog cov qauv hlau dav dav nrog qhov tsawg kawg nkaus tawm lub zog ntawm 355MPa.

S690QL yog siv rau cov ntawv thov uas xav tau lub zog siab- rau- qhov hnyav piv, xws li kev tsim kho thiab cov khoom siv hnyav, thaum S355 yog ntau dua thiab tus nqi- kev xaiv zoo rau ntau yam kev siv cov qauv.

S355J2 thiab S690QL yog cov hlau uas muaj cov khoom siv sib txawv thiab cov chaw siv:

• S355J2

Tawm Zog: ~ 355 MPa

Tensile zog: 490-630 MPa

Feem ntau siv nyob rau hauv cov nqi qis - cov ntawv thov kev tsim qauv.

• S690 qw

Tawm Zog: ~ 690 MPa

Tensile zog: 770-940 MPa

Tsim los rau cov ntawv thov uas xav tau lub zog siab.

S690 qw:

txais yuavQuenched + Tempered (Q + T)txheej txheem

Kub rau 890-930℃rau quenching, ces tempered ntawm 580-620 degree

Cov qauv tempered sorbite kom ua tiav qhov sib npaug ntawm lub zog siab thiab toughness

S355:

Feem ntau xa hauvkub- dov los yog normalizedmob

Tsis muaj kev kho cua sov yuav tsum tau ua, ua rau cov nqi tsim khoom qis dua

• Siv tau Scenario rau S690QL:

Engineering MachineryCrane booms, excavator caj npab, mining machinery thav ntawv

Bridge Engineering: Main girders ntawm ntev- ncua txuas hniav, cable- nyob twj ywm choj pylons

Marine Engineering: Offshore platforms, polar oil and gas pipelines

Tsheb tshwj xeeb: Heavy- lub luag haujlwm lub tsheb thauj khoom, cov tub rog tsheb armor

High-Rise Buildings: Ntev-span ru tsev trusses, seismic kev them nyiaj yug systems

• Siv tau Scenario rau S355:

Cov Qauv Hauv Tsev: Factory vaj tse, chaw ua hauj lwm cov thav ntawv

Infrastructure: Ordinary choj, culverts, dams

Mechanical Manufacturing: Cov khoom siv dav dav thiab kev txhawb nqa

Nkoj Engineering: General hull structures, decks

Agricultural Machinery: Lub tsheb laij teb thav duab, kev txhawb nqa khoom

Core Application Difference: S690QL yog haum rausiab -lub zog, lub teeb yuag, siab - kev ntseeg taucov qauv tseem ceeb; S355 yog siv dav hauv cov qauv dav dav nrogcov kev xav tau ntawm lub zogthiab tus nqi siab dua -kev ua tau zoo.
