APPLICATION OF NANO-SCALE PRECIPITATE ENGINEERING OF TiN-NbC COMPOSITE IN 32mm K60-E2 GRADE PLATE ROLLING

摘要：

　　A cost effective alloy design based on niobium microalloying was developed by Shagang for the production of 32 mm gage K60-E2 steel plate for manufacturing LSAW pipes of 1422 mm diameter.Two metallurgical challenges are(i)to meet enhanced CTOD toughness and(ii)to ensure consistent DWTT performance in accordance with the specification laid out by Gazprom Vniigaz.
