General Characteristics

DF 4050 has been developed specially for the forging industries. It is utilized for repair and finishing of dies and component surfaces. This is also suitable for flood welding. DF 4050 represents an ideal combination of alloys (Chromium, Molybdenum and Nickel) which display excellent resiliency, high strength and resistance to cracking. It has good machinable deposit. It enhance die life.

Applications

This alloy is an excellent choice for finishing hammer and press components, such as rams, sow blocks, shanks, die holders, bolster plates, etc. It is also used as an underlay and to fill up deep cracks in impressions where the automatic welding can not be utilized because of narrow areas. Also where conventional machining will be used that will not be part of a working area, i.e. flash lands, ribs, etc. to reduce welding material cost. Rolling mill roll, crane wheels rims, Earthmoving undercarriage parts, axles, clutches, cams, shafts couplings rail crossing points gear wheels etc.
