Following is the shape of 42CD4,40CD4 forging steel material that we could do is:42CD4 Forged Steel round bars square bars Flat bars Rectangles Bars Rods,42CD4 Forged forging steel rings seamless rolled rings,40CD4 Forged Forging Steel Hubs housing shell Sleeves Bushes Bushing Cases Hollow Bars,42CD4 forging forged steel shafts,gear,pinion shafts,spindles,gear wheel,40CD4 Forged Forging Steel Discs Disks Blocks plates,42CD4 Forged Forging Steel Pipe Tubes Tubings Piping Shells Casings Case barrels Housings.
42CD4,40CD4 offers good ductility, resistance to wear and good shock resistance properties. The presence of chromium, molybdenum, and nickel in the composition of this steel enhances its wear resistance, making it appropriate for use in harsh environments. Chromium and nickel provide good corrosion resistance; this can be further improved by applying a protective layer of another material, such as zinc or chromium. With these characteristics, it is popular high-tensile engineering steel with a tensile of 850°-1000N/mm²
The 42CD4,40CD4 forged parts shall be melted by one of the following processes:electric furnace with separate degassing and refining optional or electric furnace followed by electroslag-consumable remelting.
The minimum forging reduction ratio of 42CD4 forged bars shall be 4:1, where the forging reduction ratio is defined as the product the area reduction ratio(s) for each hot working operation performed
