Alloy 253ma Steel Phaj
Cov Khoom Piav Qhia Ntawm Ntawm No Yog Cov ncauj lus ntxaws ntawm Alloy 253ma (Cov Qauv Ntsuas Cov Qauv thiab Kev Ntsuas Cov Khoom Kub (Steel Kub) Vim Li Cas Xaiv Peb? Peb zoo siab rau peb ...
Hauj lwm lawm
Cov khoom lag luam
Ntawm no yog cov ncauj lus kom ntxaws cov khoom ntawm alloy 253ma (und under 253m7) steel phaj, sib txuas cov qauv kev sim hauv tsev thiab thoob ntiaj teb rau kev qhia thoob ntiaj teb:
I. Chav Chav Cua Kub Cov Khoom (qhov ntsuas kub)
| Cov Cuab Yeej Ntsuas Cov Khoom | Cov nqi raug (cov qauv yuav tsum tau) | Kuaj Tus Qauv | Daim Ntawv Thov Tseem Ceeb |
|---|---|---|---|
| Tensile lub zog (ulb) | Ntau dua los yog sib npaug rau 540 MPa (tom qab daws teeb meem; qee cov qauv yuav tsum muaj ntau dua lossis sib npaug 520 mpa) | ASTM A240, GB / T 20878 | Kev ntsuas cov khoom siv tiv thaiv kom tensile pob txha lov, kom muaj kev nyab xeeb hauv cov khoom zoo li qub. |
| Yield zog (σ0.2) | Ntau dua los yog sib npaug rau 240 MPa (0.2% offset paib lub zog; qee cov qauv yuav tsum muaj ntau dua lossis sib npaug rau 230 MPa) | ASTM A370, GB / T 228.1 | Cov cim rau kev ntxhov siab tseem ceeb ntawm cov khoom tsis txaus ntshai pib, ua haujlwm ua lub zog ua rau tsim. |
| Elongation (Δ5) | Ntau dua los yog sib npaug rau 35% (qee cov qauv yuav tsum muaj ntau dua lossis sib npaug rau 30%, sib txawv nrog phaj tuab) | ASTM A370, GB / T 228.1 | Xav txog cov khoom siv yas deformation muaj peev xwm; High elongation qhia tau zoo dua formability thiab cuam tshuam tsis kam. |
| Hardness (HB) | Tsawg dua los yog sib npaug rau 220 (brinell hardness; qee cov qauv uas tso cai tsawg dua lossis sib npaug rau 230) | ASTM A370, GB / T 231.1 | Kev ntsuas cov khoom siv tiv thaiv mus rau hauv nroog indentation, tsis ncaj qha rau lub zog thiab coj kev tiv thaiv. |
