3.Heat treatment methonds of S45C honed steel tube Normalizing It refers to the heat treatment process that steel parts are heated 30-50 over the critical temperature, and after certain time of heat preservation, the steel parts are cooled under immobile air condition. The main purposes of normalizing are to refine microstructure, improve steel performance and obtain a structure close to din1629 st52 steel hydraulic parts cold rolled tube(plate) SEAMLESS STEEL PIPE_Product Center_Shandong Liaocheng din1629 st52 steel hydraulic parts cold rolled tube(steel) Seamless Steel Pipe(tube) STPG370 HOT ROLLED SEAMLESS TUBE Standard JIS3445/JIS3444 Application For manufacturing of pipelines, vessels, mahine parts, pipe fittings, and steel structures.
