API released the APl5L standard in 1926, which initially included only three steel grades, A25, A and B, with minimum yield values of 172, 207 and 241 MPa, respectively. API released the APl5L standard in 1947, which added three steel grades X42, X46, and X52 with minimum yield values of 289, 317, and 358 MPa, respectively.
The chemical composition of API 5L X60 steel includes elements such as carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, and molybdenum. The precise composition varies depending on the manufacturing process used by the steel mill. The following table shows the typical chemical composition of API 5L X60 steel:
| Element | Chemical Composition (%) |
|---|---|
| Carbon | 0.26 – 0.45 |
| Manganese | 1.00 – 1.60 |
| Phosphorus | 0.030 |
| Sulfur | 0.030 |
| Silicon | 0.10 – 0.50 |
| Chromium | 0.50 |
| Nickel | 0.50 |
| Copper | 0.50 |
| Molybdenum | 0.15 – 0.25 |
