Abstract

Post processing of materials is necessary to suit them for the intended requirements. The properties of stainless steel of grade 316L cannot be influenced with further processing such as hot working [1]. Thus the current study aims at investigating the properties of stainless steel of grade 316L after being subjected to deep cryogenic treatment. The specimens from both cryogenically treated and untreated conditions were subjected to Tensile Test, Charpy Impact Test, Rockwell Hardness Test, Microstructure and Percentage Shear Area Analysis and the results thus obtained are discussed in this paper. The results have shown that cryogenic treatment has improved the hardness and strength.
