Cov Khoom Siv Khoom Sib Piv
| Khoom | Tshuaj lom neeg cov tshuaj lom neeg | Yield zog (mpa) | Tensile lub zog (mpa) | Elongation (%) | Tsawg tus kub cuam tshuam lub zog (-40 degree, j) |
|---|---|---|---|---|---|
| A36 H tshooj Beam | Cov tshuaj ntsuab steel (c tsawg dua lossis sib npaug rau {{0}}}}} | Ntau dua los yog sib npaug rau 250 | 400-550 | Ntau dua los yog sib npaug rau 20 | Ntau dua los yog sib luag rau 27 |
| A572Gr50R50H HOS QAUV | High-zog tsawg-alloy steel (c tsawg dua lossis sib npaug {2}}. 0. 05%}. 05%, grain refinement | Ntau dua los yog sib npaug rau 345 | 450-550 | Ntau dua los yog sib npaug rau 18 | Ntau dua los yog sib luag rau 27 |
| A992 H zoo li nqaj | High Manganese cov ntsiab lus (Mn ntau dua lossis sib npaug ntawm 1.35%), Txhim Kho Ntsej Muag thiab nkees ua rau muaj kev ruaj khov nyob hauv cov tuam tsev | 345-450 | 470-630 | Ntau dua los yog sib npaug rau 18 | Ntau dua los yog sib luag rau 27 |

H Qhov Kev Ua Haujlwm Hlau Kev Ua Haujlwm thiab Cov Ntawv Teev Npe
A36 H Beam khoom siv:Kev lag luam tau zoo, haum rau cov pa hluav taws xob zoo nkauj, dav corrosion tsis kam (txheej txheej saum npoo); Siv Hauv Kev Lag Luam Lub Mainge thiab cov khoom siv dav dav.
A572GR50GR50rterCal Hlau Hlau H Beam Khoom Khoom:Lub zog siab thiab lub teeb yuag (15% sib dua tshaj A36), 30% siab dua rau cov ntsev tsuag kab mob corrosion; Siv nyob rau hauv tus ntoo khaub lig-hiav txwv lub ntsiab kab teeb thiab chaw nres nkoj Crane taug kev ci.
A992 cov qauv kev ha nqaj khoom:Muaj kev qaug zog uas muaj zog tiv taus (Cyclic load lub neej yog 20% siab dua A57GR50), kev pom zoo zoo nkauj; Siv Hauv Super High-Rain Tsev Tub Ntxhais Tub Ntxhais Tub Ntxhais Thiab Chaw Tua Platform Txhawb Nqa.
