Get More Knowledge about Hammer Forging.

Hammer forging is categorized by an exact little contact time and very speedy rate of increase of force with time (impact stacking). The collective contact time for the lowermost die can be fairly long if one includes the time between blows. However, since a lubricant with “blow-out” effect is normally used with hammers, effective interaction between the part and the die only occurs throughout the actual forging blow. These features imply that impact toughness and ductility are important properties for die steel to be used in hammer dies. This does not mean to say that wear resistance is not important, particularly in smaller dies, which in fact usually fail as a result of wear. In hammer forging, there is a lot to be said for using inserts of a more wear-resistant die steel which are shrink fitted into a tough holder material.In hammer forging used many type of tool steel grade but h13 steel is maximum used. For larger, high-production hammer dies, which may be re sunk a number of times, it is important that the die steel used has sufficient hardenability that the later cavities are not sunk in laxer material with inferior wear resistance.

In hammer forging maximum used two steel grades i.e. H13 Tool Steel and D6 Tool Steel.
