Tensile Properties of Martensitic Stainless Steel Weldments
In this study, AISI 420 martensitic stainless steels were welded by GTAW (gas tungsten arc welding) using ER 316L consumables. Pure argon, argon + 25% He and argon + 5% N2 were used as shielding gases. The obtained results indicated that shielding gases have some effect on the properties of the martensitic stainless steel weldments. The use of argon+5%N2 provides the highest tensile strength values and higher microhardness profile compared to the other shielding gas composition used.
