Influence of Hot Clad Rolling Process Parameters on Life Cycle of Reinforced bar of Stainless Steel Carbon Steel Bars

Experimental trial is made to produce and manufacture of a cladding resistance reinforced bars of stainless steel- low carbon steel bars. Grooved rolling with different; passes design, clad rolling temperature, rolling speed, rolling direction and reduction ratio are employed to investigate clad bars properties experimentally. Tensile test and microstructure observation was done on the manufactured samples of clad bars to examine the rolling conditions on mechanical and microstructure properties; size and shape of bonded line region, and microstructure of stainless steel and low carbon steel for each cladding conditions. A comparison with the required specification for reinforced bars was done to choose the best production parameters. Results, shows that Rolling temperature, rolling direction and reduction ratio have more effect on clad bonding zone size and mechanical properties than rolling speed.
