- HIGH YIELD STRENGTH STEELS
130ksi
Description
Low-alloy rod for steels with high yield strength
This high-strength low-alloy rod is designed for welding similar composition alloys that require a minimum tensile strength of 130 ksi. It exhibits good mechanical properties and is suitable for applications on heavily stressed structures. To achieve high static strength and impact toughness in the welded joint, it is important not to exceed a heat input of 0.8 kJ/mm during welding. It is advisable to stress relieve the weld by applying a post-weld heat treatment.
