Qhov txawv ntawm API 5L X60 thiab X52 yog dab tsi?
Cov lus sib piv ntawm API 5L X52 vs X60 Core Parameters
| Parameter | X52 (L360) | X60 (L415) | Kev cuam tshuam ntawm qhov sib txawv |
|---|---|---|---|
| Yam tsawg kawg nkaus Yield Strength | 360 MPa (52 ksi) | 415 MPa (60 ksi) | ▲ X60 muaj 15% siab dua -cov kabmob muaj peev xwm |
| Tensile Strength Range | 455-570 MPa | 520-670 MPa | ▲ X60 zoo dua rau kev siv siab -siab |
| Carbon sib npaug (CEIIW) | Tsawg dua lossis sib npaug li 0.45% | Tsawg dua lossis sib npaug li 0.48% | △ X60 yuav tsum tau kub preheating rau vuam |
| Hom Phab Ntsa Thickness (24 "pib) | 10.3 hli | 9.1mm ib | ▼ X60 txo qhov hnyav los ntawm 12% nyob rau hauv tib lub siab |
| Impact Energy Requirement ntawm -20 degree | Ntau dua lossis sib npaug li 40 J | Ntau dua lossis sib npaug li 45 J | ▲ X60 muaj siab dua -kub toughness yuav tsum tau |
| Kev ntsuas ntsuas siab | Tsawg dua lossis sib npaug li 10.3 MPa | Tsawg dua lossis sib npaug li 12.1 MPa | ▲ X60 yog haum rau ultra-siab- kis tau tus mob |
| Tus nqi sib txawv ib kilometer | Puag | +18%~22% | ▼ X52 yog tus nqi ntau dua -zoo |
Qhov hardness ntawm API 5L X52 yog dab tsi?
API 5L X52 steel muaj qhov tseem ceeb hardness ib puag ncig237 HB(Brinell Hardness), txawm hais tias hardness tsis yog thawj specification; Hloov chaw, nws tau txhais los ntawm qhov tsawg kawg nkaus tawm los (52 ksi lossis 360 MPa) thiab lub zog tensile (66.7 ksi lossis 460 MPa).
