Txawm hais tias ob qho tib si API 5L X65 thiab ASTM A106 (feem ntau xa mus rau A106 Qib B) yog cov pa roj carbon steel kav, lawv koom nrog cov kev siv sib txawv kiag li.
API 5L X65: tsom rau "siab- kev thauj mus los muaj zog" thiab siv rau ntev - cov kav dej thiab cov kav dej.
ASTM A106: tsom rau "siab-kub thiab siab- ib puag ncig siab" thiab siv rau cov txheej txheem piping hauv refineries thiab fais fab nroj tsuag.

| Tensile zog (min) | 535 MPa (77,600 psi) | 415 MPa (60,000 psi) | X65 tuaj yeem tiv taus ntau dua sab hauv siab. |
| Elongation | High (optimized rau ductility). | Standard (optimized rau khoov / sib sau). | Ob leeg muab kev ua haujlwm zoo heev. |
| Impact Testing (CVN) | Yuav tsum tau(feem ntau ntawm 0℃lossis -20 degree). | Tsis tas yuav tsum tau (tshwj tsis yog teev). | X65 yog qhov zoo tshaj rau qhov txias - huab cua siv sab nraum zoov. |
Chemical Composition Comparison (Max %)
| Element (Max %) | API 5L X65 (PSL2) | ASTM A106 Qib B | Qhov txawv tseem ceeb |
| Cov pa roj carbon (C) | 0.12 (Variations ntawm hom) | 0.30 | A106 muaj C siab dua; yuav tsum tau preheating rau vuam. |
| Manganese (Mn) | 1.60 | 0.29 – 1.06 | X65 siv ntau dua Mn kom ua tiav cov txiaj ntsig siab. |
| Silicon (Si) | 0.45 | 0.10 (tsawg kawg) | A106 yuav tsum muaj Siliconrau "tua steel" tshav kub tsis kam. |
| Phosphorus (P) | 0.025 | 0.035 | X65 muaj kev tswj hwm impurity nruj dua. |
| Sulfur (S) | 0.015 | 0.035 | Tsawg sulfur hauv X65 txhim kho HIC tsis kam. |
| Micro{0}} alloys (Nb/V/Ti) | suav nrog (Micro-alloyed) | Tsis xav tau | X65 yog ib qho zoo - nplej, siab - lub zog steel. |
