Assessment of Mechanical and Metallurgical Properties of

Electron beam welding produces very narrow and deep penetration therefore it finds application where welding of thick materials is required. AISI 321 is susceptible to intergranular corrosion when it is used in high temperature and harsh conditions, owing to the ium depletion in the weld zone. However, the heat affected zone formed in electron beam welding extends to a narrow region Diimila ficion i elding of AISI 430 feiic and AISI 304L Dissimilar joints of AISI 430 ferritic and AISI 304L austenitic stainless steels were produced by friction stir welding process.

Micro friction stir lap welding of AISI 430 ferritic

In this study, the effect of friction stir welding of AISI 430 (X6Cr17, material number 1.4016) ferritic stainless steel is examined. Two thin sheets with dimensions of 0.4 × 50 × 200 mm 3 are joined in lap configuration. Optical microscopy and field emission electron microscopy were used in order to microstructural evaluations and fracture analysis, respectively. Stainless Steel Grade 430 - Austral WrightGrade 430 is ferritic chromium steel, with useful corrosion resistance. It has good formability and fabrication characteristics, although inferior to the austenitic stainless steels. In most applications the steel is used where the corrosion environment is only mildly aggressive, when it gives long lasting appearance and service life. Stainless Steels - Harry BhadeshiaAn alternative is use solutes (such as Nb, Ti, V or Ta) which have a greater affinity for carbon than chromium. These are called stabilisedstainless steels, for example, types 321 (Ti stabilised) and 347 (Nb stabilised) austenitic stainless steels.ium cannot in general be used to make alloys deposited by arc welding because it readily oxidises; type 347 is used instead as a filler metal.

Stainless Steels Welding Guide - Lincoln Electricfrom fully austenitic to fully ferritic. 2.0 TYPES OF STAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group. The Effect of Welding Speed on the Laser Welding of AISI Abstract In this study, the effect of welding speed on the laser welding of AISI 430 ferritic stainless steel with AISI 1010 low-carbon steels was investigated. Laser welding experiments, were carried out under argon atmosphere, 2000 W constant welding power and 100, 200, 300 cm/min welding speeds.

In friction welding of austenitic-ferritic stainless steel, deformation is confined to ferritic stainless steel only.

Micro Laser Welding of AISI 430 Ferritic Stainless Steel

In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of the welds. Also, vi-
