A500 GRB yog dab tsi
A500GRB yog lub siab -kev ua tau zoo steel yeeb nkab feem ntau siv hauv kev tsim kho, txuas hniav, thiab lwm yam kev tsim vaj tsev. Nws muaj cov khoom siv zoo heev thiab kev tiv thaiv corrosion, uas tso cai rau nws tiv taus cov khoom hnyav thiab kev kub ntxhov. A500GRB plaub lub raj muaj lub ntsej muag zoo nkauj thiab zoo nkauj, ua rau nws tsim nyog rau kev ua thiab pleev xim. Nws cov qauv ua raws li cov kev cai ntawm American Society for Testing and Materials (ASTM).
A572 GR50 yog dab tsi
ASTM A572 GR50 yog lub siab -lub zog qis- alloy (HSLA) steel, uas yog hom hlau microalloyed siv cov khoom xws li niobium, vanadium, lossis titanium. Qhov sib ntxiv ntawm cov alloying ntsiab no txhim kho lub zog thiab kav ntev ntawm cov hlau tsis muaj qhov hnyav nce, ua cov khoom siv no feem ntau siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog siab thiab qhov hnyav yog qhov tseem ceeb.
Qhov txawv ntawm A500 Qib B thiab A572 Qib 50 yog dab tsi?
| Cov khoom sib piv | ASTM A500 Qib B | A572 Qib 50 |
|---|---|---|
| Khoom siv | Txias-tsim tubing(Square / Rectangular / Round) | Kub- dov steel phaj / ntu(H-beams/Angles) |
| Core Application | Tubular kev them nyiaj yug qauv (Shelving / teeb trusses) | Hnyav load-cov kabmob(Bridges/siab-nce ncej) |
| Yield zog | 290 MPa rau | 345 MPa rau(19% siab dua) |
| Tensile zog | 415 MPa rau | 450 MPa |
| Alloy Composition | Plain carbon steel (C Tsawg dua lossis sib npaug li 0.26%) | Tsawg- hlau alloy(Vanadium / Niobium, zoo dua corrosion kuj) |
| Kev sib txuas Advantage | Ua ntej-fitting kawg connectors, hloov tau yooj yim | Zoo dua rau ntawm - qhov chaw vuam / siab - lub zog bolting |
Dab tsi yog qhov yield zog ntawm A500 steel qauv?
A500 Qib B thiab C Cov Qauv Tubing Hlau
| Imperial | |
|---|---|
| Tensile zog, yam tsawg kawg nkaus | 62,000 psi |
| Tensile zog, Yield Yam tsawg kawg nkaus | 50,000 psi |
