A Study on the Development of Induction Bright Annealing System for Stainless Steel Welded Pipe & Tubes
- 발행 : 1992.12.31
초록
This study aimed to develop the heat treating equipment which could produce austenitic stainless steel welded pipes & tubes maintaining its peculiar brightness even after heat treatment. The results of this study are as follows:- Development of 8.5kHz, 150kw bright annealing system was achieved. - Bright annealing of austenitic stainless steel welded pipes & tubes was performed by the developed pilot-system through this study and heat-treatment effects were quite successful in viewpoint of surface brightness, hardness distribution, microstructure, removal of residual stress, strength and corrosion resistance.
