hardening Problem

(OP)
Hello friends,
              i am facing some problem in hardening Die Steel Plates of width 2 inches and width 1 feet, actually they warp while hardening, i have to harden 3 such plates at a time, can anybody suggest how the hardening should be carried out to rempve  or minimise such a defect.
               Thank you for any help.

RE: hardening Problem

Comeback with more information.

What is the material?

What is your current heat treatnment procedure?

How much warpage?

RE: hardening Problem

If the plates are air hardening type then your work is easy. if they need faster rate of cooling then design a hanger so that the plates can be suitably hung  vertically and during quenching maintain the same . Avoid the plates falling face  flat during quenching. These measures will help reduce warpage,but not eliminate.

RE: hardening Problem

Depending on what sort of tolerances you need you may need to blanchard grind/flycut/etc... after hardening to meet required geometry.
