The heat-resisting steel is produced by a process comprising the steps ofadding Ti, Zr, Ta and Hf to a molten steel having chemical components as mentioned above, during the period from 10 minutes before completion of refining to completion of refining, casting said molten steel, working the resulting casting, solution treating said worked product, subjecting said worked product to temporary cooling stop at a temperature from 950.degree. to 1,000.degree. C. in the course of cooling said hot worked product, and holding said worked product at the temperature for 5 to 60 minutes. The heat-resisting steel is excellent in HAZ-softening resistance, and exhibits a high creep strength at high temperature of at least 550.degree. C.

    摘要: A martensitic heat resistant steel is provided which has improved high temperature creep strength, contains Co and, at a temperature of 600.degree. C. or above, does not form an intermetallic compound substantially having a composition of Cr.sub.40 Mo.sub.20 Co.sub.20 W.sub.10 C.sub.2 --Fe. In a heat-resistant steel, containing not less than 8% of Cr, with Co, Mo, and W being simultaneously added thereto, a combination of the addition of a very small of Mg, Ba, Ca, Y, Ce, La and the like, with the addition of a minor amount of Ti and Zr, inhibits the precipitation of an intermetallic compound substantially having a composition of Cr.sub.40 Mo.sub.20 Co.sub.20 W.sub.10 C.sub.2 --Fe, thereby ensuring high temperature creep strength.
