Abstract

Reinforcing rods for concrete are made of an alloy steel having a percentage composition as follows:-Carbon 0.38-0.43, manganese 0.60-0.80, phosphorus 0.04-maximum, sulphur 0.04-maximum, silicon 0.20-0.35, nickel 1.65-2.00, chromium 0.70-0.90 and molybdenum 0.20-0.30. The rods are heat treated by electric induction, the rods being fed through a series of induction coils and quenching chambers. The steel is uniformly heated to 1275 DEG F., quenched to room temperature, reheated to 450 DEG F. and allowed to cool slowly to room temperature.
