A533 qib B rau lub siab ntsha phaj siab

Cov yam ntxwv tseem ceeb ntawm A533 Qib B Siab Ntses Daim Hlau:

Alloy muaj pes tsawg leeg:

Feem ntau tsim ntawm manganese, molybdenum, thiab npib tsib xee, pab txhawb nws lub tswv yim xav tau cov cuab yeej |.

Kev Kho Cua Sov:

Feem ntau muab rau hauv cov quenched thiab tempered mob, txhim kho nws lub zog thiab tawv .

Lub zog:

Cov khoom ua pov thawj siab thiab tawm lub zog nyob ib ncig ntawm 90, {}}}} psi, ntsig.

Taus:

Muaj cov noch tsis muaj zog zoo, qhov tseem ceeb rau kev tiv thaiv brittle fracture hauv cov hlab siab siab .

Weldability:

Tuaj yeem muab tso rau welded siv ntau hom kev kawm, ua rau nws haum rau fabricating complex qauv qauv {}}

Cov Ntawv Thov:

Dav siv nyob rau hauv lub zog hluav taws xob rau reactor cov hlab ntsha thiab lwm lub siab-muaj cov roj thiab roj kev lag luam rau cov hlab roj siab.

Qauv:

Conforms rau ASTM A533 / A533m specifications .

Cov kev txiav txim siab tshwj xeeb rau A533 qib bit bit:

Qhov tuab:

A533 Qib B cov phiaj tuaj yeem tsim nyob rau hauv ntau thicknesses, nrog qee tus neeg xa khoom muaj daim hlau kom txog li 350mm tuab .
