Abstract

PURPOSE: To enhance the toughness, weldability and heat treatability on the superhigh strength level by adding a prescribed amount of Si, C, Mn, P, S, Ni, etc. to Fe.
CONSTITUTION: This superhigh tensile steel consists of ≤0.5% C, ≤0.3% Si, ≤0.3% Mn, ≤0.05% P, ≤0.05% S, 10W25% Ni, ≤2% Co, 0.5W4% Mo, 0.5W 5% Ti, 0.1W3% Al and the balance Fe. This steel is heated at the Af temp. or above to form an austenite monophase, and it is cooled to ordinary temp. and subjected to soln. heat treatment. Aging is then carried out at about 300W650°C to further ensure weldability and heat treatability.
