These guidelines are based on forming at typical shop temperatures over +60�F.* We caution that bend forming of these hard steels should be carried out using shop practices which include, but are not limited to, using hardened V-dies with a liberal radius (See Table 2). Also, adequate lubrication, grinding of plate edges and applying the load in a smooth, steady manner is recommended. Particular caution should be used in applying the "bump and move" technique to control the depth and number of bends.

Examples of bends formed from Hardwear 400F plates, using the guidelines of Table 2, are shown below.

*Hardwear steels are not intended for hot forming applications, unless reheat treatment of the part is included. Consult BLP for heat treatment guidelines.
