Abstract

The strength characteristics of stainless steels can be enhanced by a form of alloying (in particular, with nitrogen) that hardens the solid solution, by dispersion hardening, and by the formation of an austenitic-ferritic or martensitic structure. All of such methods, except solid-solution hardening, entail the formation of a heterogeneous structure and will sometimes reduce the corrosion resistance of the steel. On the other hand, austenitic stainless steel can be strengthened without polymorphic transformations by thermomechanical treatment (TMT). As applied to stainless steels, this involves controlled rolling with precisely specified temperature range, strain rate, amount of strain, and cooling rate at the end of deformation. This study was concerned with the influence of various TMT schedules on the mechanical properties, corrosion resistance, structure, and weldability of 08Kh18N10T and 03Kh18N11 steels produced in the laboratory and commercially.
