ABSTRACT:
A high strength electric furnace, vacuum degassed and weldable seamless tube of low alloy steel containing 0.22 to 0.28% carbon, 1.20 to 1.4% manganese, not more than 0.035% phosphorus, not more than 0.02 sulphur, 0.15 to 0.35% silicon, 0.20 to 0.30% chromium, not more than 0.05% nickel, 0.15 to 0.60% molybdenum, 0.02 to 0.04% titanium, 0.0007 to 0.0025% boron, 0.007 to 0.050% aluminum and the balance iron. Where the pipe has a wall thickness of 11/8 inch or less the percentage molybdenum is preferably 0.15 to 0.20% whereas if the wall thickness is 1.18 inches or greater the preferred molybdenum content is 0.40 to 0.60%. The pipe is preferably heated to an austenization temperature of about 1,550.degree. F. followed by simultaneous internal and external quenching and tempering at a temperature of about 1140.degree. F.
