Evaluation of properties of AISI 431Grade Stainless Steel by Vacuum Annealing Process

Abstract

The wear behaviour of AISI 431stainless steel was investigated at consistent load under a dry sliding touch with vacuum annealing device. The approach implemented was found to have been effective in improving the wear actions of stainless steel products, advancing the pliability properties. For Vacuum Annealed (VA1) 2 hours, Vacuum Annealed (VA2) 4 hours and Vacuum Annealed (VA3) 6 hours respectively, a low temperature heat treatment was performed on sample for the maximum annealing cycle. Untreated stainless steel (UNT) was used as a kind of viewpoint tool for contrast with specific hardening samples and conducted wear checks. The hardening samples show certain hard formed layers which enhance the hardness of the surface. Estimations of small scale toughness showed a crucial improvement in toughness following operation. This method raises the hardness of the substance up to 150 percent. A pin on the disc drive is used to do wear checking to assess wear failure. The layers were represented by optical lens magnification and the examination of electron magnifying glass.

Effect of Aqueous Soluted Nitriding Process on AISI 304 Austenitic Stainless Steel under Dry Sliding Conditions

“…Much of the research and development on stainless steel continues and generate novel ideas for improvement on the mechanical properties. Development of austenitic stainless steels with improved properties started since 1980s [11][12][13]. These materials are widely used for low temperature applications such as nuclear power plants, food processing industries, petrochemical industries etc.…”

Influence of aisi 304 austenitic stainless steel by aqueous soluted nitriding and gas nitriding

“…Downtime and replacement cost expenses are also included in financial depreciation losses. Wear is identified as the source of abrasive wear [9][10]. Abrasives are the primary source of most industrial wear issues.…”
