Abstract
PURPOSE: To provide a steel for low temp. use with superior toughness in the weld heat-affected zone especially at -40W-60°C by adding a predetermined percentage each of C, Mn, Si, Al, P, S, N and Ti and/or B and restricting the value of Ceq to a specified value or below.
CONSTITUTION: This steel for low temp. use contains 0.005W0.13%, especially 0.03W0.10% C, 0.7W2.2% Mn, ≤0.3% Si, 0.01W0.1% Al, ≤0.025% P, ≤ 0.024% S, 0.005W0.0100% N and 0.006W0.025% Ti and/or 0.0006W0.0025% B, and it has ≤0.37 Ceq represented by the equation as an essential condition. The steel has improved toughness and ≤-55°C Charpy fracture transition temp. vTs in the weld heat-affected zone. The toughness of a weld heat-affected zone, which is most serious in case of an Al killed steel used especially at -40W-60°C, is improved.
