日本国家金属研究院近日称,用于高抗拉强度钢的新型焊接材料实验阶段的开发研究已经开展,以满足在焊接过程中对预热的要求。添加镍和铬元素的新材料较低温度条件下开始其马氏体相变过程。由于镍和铬的共同影响,新材料在正常温度条件下产生最大的马氏体相变区。高抗拉强度钢焊接
Japan’s National Institute of Metal Research recently said that the development of new experimental phase of welding materials for high tensile strength steel has been developed to meet the preheating requirements during the welding process. New materials added with nickel and chromium begin their martensitic transformation at lower temperatures. Due to the combined effect of nickel and chromium, the new material produces the largest martensitic transformation zone at normal temperatures. High tensile steel welding
