American standard H-beams ua los ntawm ASTM A992 thiabASTM A572 Qib 50yog ob qho ntawm cov khoom siv hlau feem ntau siv hauv kev tsim kho, choj engineering, thiab kev tsim khoom hnyav.
Ob qib raug cais raws li siab -lub zog qis- alloy (HSLA) steels thiab muab qhov sib npaug zoo ntawm lub zog, toughness, thiab weldability.
ASTM A992 H-beam yog tsim raws li ASTM A992/A992M specifications thiab yog dav siv nyob rau hauv siab-nce vaj tse thiab hnyav structural ncej.
Nws muaj qhov tsawg kawg nkaus lub zog ntawm 345 MPa, lub zog tensile ntawm txog 450 MPa, thiab elongation ntawm kwv yees li 18%, muab cov khoom zoo heev -cov kabmob muaj peev xwm thiab kev ua haujlwm zoo.
ASTM A572 Qib 50 yog lwm yam HSLA cov qauv hlau tau teev tseg hauv qab ASTM A572 / A572M. Nws nta cov qib zoo sib xws, zoo ductility, thiab txhim khu kev qha weldability, ua rau nws tsim nyog rau cov txuas hniav, lub tsev thav duab, thiab cov khoom siv tshuab.
A572 Qib 50 H-beams feem ntau muaj qhov tsawg kawg nkaus lub zog ntawm 345 MPa, tensile zog ntawm 450 MPa los yog siab dua, thiab elongation nyob ib ncig ntawm 21%, kom ntseeg tau tias lub zog thiab formability.
Cov txheej txheem American H-cov ntaub ntawv beam suav nrog ASTM A36, A572, A709, A992, A913, nrog rau cov qib sib npaug xws li Q355B.
Puas yog A572 yooj yim rau tshuab?
ASTM A572 steel phaj yog siab -lub zog, qis- alloy structural steel uas yooj yim formable, machinable, thiab weldable. Lub zog zoo heev - rau - qhov hnyav piv txhais tau tias cov khoom siv tsawg dua yuav tsum tau ua kom tiav.
A572 steel siv rau dab tsi?
A572 steel pom dav siv hauv kev tsim kho thiab tsim khoom. Nws lub zog siab -rau- qhov hnyav piv ua rau nws zoo tagnrho rau cov khoom siv xws li txuas hniav, cov tsev steel hlau, thiab cov khoom loj, qhov chaw ruaj khov thiab thauj khoom -cov kabmob muaj peev xwm tseem ceeb heev.
Dab tsi yog qhov specification ntawm ASTM A572?
ASTM A572 specification yog tus qauv Specification rau High-Strength Low-Alloy Columbium-Vanadium Structural Steel rau daim hlau siv dav siv hauv kev tsim kho thiab cov qauv siv. ASTM A572 suav nrog tsib qib nrog cov txiaj ntsig tsawg kawg nkaus ntawm 42, 50, 55, 60, thiab 65 ksi, feem.
Puas yog A572 muaj zog dua A36?
Qhov muaj ntau dua ntawm cov khoom siv ntxiv dag zog, xws li manganese thiab silicon, hauv A572 phaj qib muab cov khoom muaj zog dua piv rau A36. Lub zog siab dua no tso cai rau A572 steel ris hnyav dua thiab tiv taus ntau dua yam tsis muaj kev tawg lossis ua tsis tiav, uas yog qhov tseem ceeb hauv kev siv cov qauv.
Koj puas tuaj yeem txuas A572 steel?
Qhov muaj ntau dua ntawm cov khoom siv ntxiv dag zog, xws li manganese thiab silicon, hauv A572 phaj qib muab cov khoom muaj zog dua piv rau A36. Lub zog siab dua no tso cai rau A572 steel ris hnyav dua thiab tiv taus ntau dua yam tsis muaj kev tawg lossis ua tsis tiav, uas yog qhov tseem ceeb hauv kev siv cov qauv.
Puas yog A572 siab carbon steel?
A572 yog ib qho qis- carbon steel nrog zoo weldability thiab nruab nrab lub zog, feem ntau siv rau hauv cov qauv siv.
Puas yog A572 steel corrosion resistant?
A572 steel feem ntau yog siv rau hauv cov qauv siv vim nws lub zog siab, ductility, weldability thiab corrosion kuj.
Lub hardness ntawm A572 steel yog dab tsi?
Nrog nws qhov ceev, lub zog tawm los, thiab Brinell Hardness ntawm 135, A572-50 yog qib nyiam rau ntau hom kev siv hnyav.
