| titleOfInvention | High-pass temperature multi-pass welded steel material, method for producing the same, and high-pass temperature multi-pass weld method. |
| abstract | [PROBLEMS] To provide a steel material for high interpass temperature welding having sufficient HAZ toughness even when the interpass temperature reaches 350 ° C. or higher, a method of manufacturing the same, and a welding method using the same. SOLUTION: A step of adding ferromanganese or silicomanganese to molten steel discharged from a converter to preliminarily deoxidize so that the dissolved oxygen amount becomes 0.0030 to 0.0120% (mass ratio, the same applies hereinafter). Adding REM to adjust the dissolved oxygen amount to be 0.0010 to 0.0050% and the remaining amount of REM in the steel to be 0.0010 to 0.03%, and C: 0.03 to 0.03%. 0.15%, Si: 0.05 to 0.50%, Mn: 0.5 to 2.0%, P: 0.03% or less, S: 0.0005 to 0.0080%, REM: 0. The molten steel obtained by sequentially performing the steps of adjusting to a final steel composition containing 0010 to 0.03%, the balance Fe and unavoidable impurities is cast to obtain a steel ingot, and after heating the steel ingot, it is heated to a final product shape. After rolling, to a temperature of 500 ° C or less at a speed of 1 ° C / s or more The recuperation temperature after cooling is stopped while retirement is prepared by a 100 ° C. or less. |
