Overview of Spring steel round bar

Spring steel round bar is suitable for a wide variety of spring applications including flat springs, clutches, knives, doctor blades, saw blades, agricultural tools, wood cutting saws, shims, knives, blades, shims, washers, masonry tools. When heat treating EN42 temperatures, including the rate of heating, cooling and soaking times, etc. will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium, and workpiece transfer facilities. Please consult your heat treatment provider for full guidance on the heat treatment of spring steels.
