ASTM A572 Qib 60 steel Khoom Taw qhia
ASTM A572 / A572M tus qauv yog thawj zaug hauv xyoo 1964, thiab tau dhau los ua ib tus qauv siv dav tshaj plaws rau kev tsim cov khoom steel. Cov hlau no tau siv dav hauv ntau daim ntawv thov thoob plaws ntiaj teb hauv ntau qhov kev lag luam. Nws tau tsim los muab cov khoom siv muaj zog, tsis tshua muaj alloy siv rau hauv cov txuas hniav, cov tsev, thiab lwm yam kev siv cov qauv.
ASTM A572 Qib 60 Cov Khoom Siv Hlau
ASTM A572 / A572M tus qauv qhia cov tshuaj muaj pes tsawg leeg ntawm cov hlau, suav nrog carbon, manganese, phosphorus, sulfur, silicon, chromium, tooj liab, npib tsib xee, molybdenum, thiab lwm yam kab kawm. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau yuav nyob ntawm qib xaiv.
ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M yog cov hlau thiab carbon thiab lwm yam khoom. Vim nws lub zog tensile siab thiab tus nqi qis, nws yog ib qho tseem ceeb ntawm cov khoom siv hauv tsev, infrastructure, cov cuab yeej, nkoj, tsheb, tshuab, khoom siv. ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M tshuaj lom neeg muaj pes tsawg leeg txiav txim siab los ntawm kev tsom xam ladle yuav tsum ua raws li cov lus teev tseg hauv qab no.

ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M Mechanical Properties
Ib qho zoo ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M steel yog nws lub zog. Cov hlau no muaj lub zog ua haujlwm siab thiab muaj qhov hnyav-rau-lub zog sib piv. Qhov no ua rau nws zoo tagnrho rau kev siv ntau yam kev tsim kho. Tsis tas li ntawd, ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M steel yog qhov yooj yim rau kev tsim thiab vuam.
Taw qhia txog cov khoom siv kho tshuab ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M:
Yield point (σs) Thaum qhov kev ntxhov siab ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M lossis cov khoom kuaj tau dhau qhov kev txwv tsis pub muaj zog, txawm tias qhov kev ntxhov siab tsis nce, ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M lossis cov qauv yuav txuas ntxiv mus rau qhov pom tseeb ntawm cov yas deformation. Qhov tshwm sim no hu ua yielding, thiab qhov tsawg kawg nkaus tus nqi kev ntxhov siab thaum yielding tshwm sim yog hu ua yield point.
Tensile zog (σb): Qhov siab tshaj plaws ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M thaum lub sij hawm nro txij thaum pib mus rau lub sijhawm tawg. Nws qhia txog lub peev xwm ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M los tiv thaiv pob txha.
Elongation (δ): Qhov feem pua ntawm cov yas elongation ntev mus rau qhov qub qauv ntev yog hu ua elongation.
Yield-strength ratio(σs/σb): Qhov piv ntawm qhov taw tes tawm (yield zog) rau lub zog tensile ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M yog hu ua nws lub zog sib piv. Qhov ntau dua qhov yield-strength ratio, qhov siab dua qhov kev ntseeg ntawm cov khoom siv.
Hardness: Hardness yog lub peev xwm ntawm ASTM A572 Qib 60 Hom 2 ASTM A572 / A572M los tiv thaiv cov khoom tawv nias rau hauv nws qhov chaw. Qhov siab dua qhov hardness, qhov zoo dua qhov hnav tsis kam.
