HIGH STRENGTH, WELDABLE, LOW ALLOY STEEL |
| 摘要 |
High-strength steel having a tensile strength of 80 kgf/mm2 or more is produced by one-line quenching or on-line quenching and tempering. The steel has also excellent low-temperature toughness and excellent weldability, which makes high temperature preheating unnecessary prior to welding. The composition is: C=0.04% to 0.11%; Si</=1.0%; Mn=0.5% to 2.00%, Mo=0.10% to 1.0%, Nb=0.005% to 0.05% B=0.0009% to 0.0012% Al</=0.1%; and N</=0.0060%. |
