dc.description.abstractMartensitic stainless steels, based around AISI 420 grade, are being increasingly specified for the production of small to medium sized moulds, which are used to manufacture high value-added plastics components for use in the automotive and food packaging industries. However, the increasing complexity of modern die design is leading to an increased incidence of mould failure due to (a) fracture as a consequence of the build-up of high residual stresses during heat treatment and (b) stress corrosion cracking in water channels. The response of the international steel industry has been to introduce modified grades of AISI 420 to overcome these problems. However, there have been no reports to date of the effect of such modification on the generation of residual stress as a function of key heat treatment parameters. ln the present study, neutron diffraction was used to identify the bulk residual stress distribution as a function of the quench rates in high pressure vacuum heat treatment for two different grades of AISI 420. Details of the results plus their analysis in terms of hardenability of the steels will be presented and discussed in the paper. © 2005 The Authorsen_AU
