Welding of Stainless Steel. 1. Features of stainless steel. By adding chromium (Cr) to iron (Fe), iron becomes resistant to corrosion in the atmosphere. When the Cr content increases to 1112% or more, the corrosion resistance of steel becomes remarkably high. Hence, the steel with such a high amount of Cr is given a name of stainless steel

Feb 02, 2013 · 304L Stainless Steel, Semi -Solid Processing, Microstructure, Tensile Properties, Hardness . 1. Introduction . AISI type 304L austenitic stainless steel (304L SS) is widely used in power, chemical, petrochemical and nuclear industries. Conventionally, stainless steels are fabricated by casting and forging processes. However, Pulsed Nd:YAG laser welding of AISI 304 to AISI 420 Sep 01, 2007 · Abstract. The technique to weld AISI 304 stainless steel to AISI 420 stainless steel with a pulsed Nd:YAG laser has been investigated. The main objective of this study was to determine the influence of the laser beam position, with respect to the joint, on weld characteristics. Specimens were welded with the laser beam incident on the joint and
