Abstract

Paper deals with the martensitic stainless steel (MSS) after reversed extrusion and broaching, quenching into polymer from austenitization temperature of 1130 °C and subsequently tempered at 480 °C with final cooling in the air. Wall thickness of cylinders corresponded to 5 mm. Subsequently some cylinders were cyclically loaded. Basic mechanical properties and microstructure features together with fracture analysis of cylinders before and after cyclic loading were compared.
