GEN 430NLb Overview
GEN 430NLb is stabilized ferritic steel, which offers superior mechanical properties to 430 grade. In addition, its fatigue resistance is also higher, the fact that lead to its spontaneous popularity in the automotive industry. This product is also used for overlay cladding as well as in thermal spray applications. Preheating of the joint to a minimum of 300°F is recommended. Welding must be done with very low heat input.
