Abstract
The tempering behaviour of AISI 403 martensitic stainless steel over t he temperature range from 480 to 720-degrees-C has been investigated. with particular attention being paid to the secondary hardening and se nsitization effects produced by the formation of alloy carbides during tempering. The secondary hardening effect was determined by means of a standard hardness test. The extent of sensitization and its effect o n the mechanical properties of the tempered steel were assessed by mea ns of a modified Strauss test and a low speed tensile test in brine re spectively. The results show that the following four distinctive proce sses occurred during tempering of AISI 403 martensitic stainless steel : annealing, secondary hardening, sensitization and healing. The tempe ring conditions over which each of these tour processes dominates are presented in the form of a tempering map for easy reference.
