Taw qhia rau ASTM A588GRA Steel

Standard thiab SpecificationASTM A588 yog ib qho kev qhia tshwj xeeb rau cov hlau tsis muaj zog tsawg. "GRA" hauv ASTM A588GRA qhia txog qib tshwj xeeb hauv qhov kev qhia tshwj xeeb no. Cov hlau no yog tsim los muab lub zog zoo thiab ua haujlwm ntev, tshwj xeeb tshaj yog nyob rau sab nraum zoov thiab corrosive ib puag ncig.

Tshuaj muaj pes tsawg leegASTM A588GRA steel muaj cov khoom xws li carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), tooj liab (Cu), thiab lwm yam. . Qhov tshwj xeeb muaj pes tsawg leeg yog ua tib zoo tswj kom ua tiav cov khoom xav tau thiab kev tiv thaiv corrosion. Piv txwv li, nws yuav muaj nyob ib ncig ntawm 0.19% carbon, 0.80-1.25% manganese, 0.30-0.65% silicon, thiab me me ntawm alloying ntsiab xws li tooj liab thiab chromium.

 

 

 

A588GrA steel uas belongs rau lub zog siab qis alloy steel kuj yog ib hom atmospheric corrosion resistant steel raws li ASTM tus qauv. A588GrA steel tau siv dav hauv cov khoom siv huab cua thiab cov khoom siv txuas hniav.

A588GrA steel nto kho: pleev xim, coated los yog galvanized

A588GrA steel Kev Xa Khoom: cov chaw kho cua sov rau kub dov, tswj dov, normalizing, annealing, tempering.

 

 

 

Mechanical Properties

Lub zog: Cov hlau no muaj zog tensile siab thiab yield zog. Lub zog tensile muaj peev xwm nyob ib ncig ntawm 485 MPa rau 620 MPa, thiab lub zog tawm los yog feem ntau nyob rau hauv thaj tsam ntawm 345 MPa rau 450 MPa. Lub zog siab no tso cai rau nws siv rau hauv cov qauv siv uas hnyav hnyav yuav tsum tau txais kev txhawb nqa.

Toughness: ASTM A588GRA steel kuj pom zoo toughness, uas txhais tau hais tias nws muaj peev xwm nqus tau lub zog yam tsis muaj fracturing. Qhov no yog ib qho tseem ceeb rau cov ntawv thov uas cov qauv yuav raug rau dynamic loads lossis cuam tshuam. Lub toughness yog ua tiav los ntawm kev sib xyaw ua ke ntawm kev sib raug zoo thiab kev kho cua sov.

Ductility: Nws muaj qee qhov ductility, ua rau nws deform plastically ua ntej tsis ua haujlwm. Cov cuab yeej no muaj txiaj ntsig zoo thaum tsim cov txheej txheem xws li khoov thiab tsim, nrog rau cov xwm txheej uas cov qauv yuav ntsib qee qhov deformation yam tsis muaj kev puas tsuaj loj.
