Abstract

This study aims to investigate the effect of the annealing process on the microstructure and hardness of AISI 410 stainless steel. AISI 410 steel is a martensitic steel known for its high strength and hardness, but it tends to be brittle. Through the annealing process, it is expected that mechanical properties will change, improving toughness and reducing material brittleness. The annealing process was conducted at 900°C for 30 minutes, followed by cooling in the furnace until room temperature was reached. Characterization was performed using metallographic testing with a Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS), as well as Rockwell hardness testing (ASTM E18). The results of microstructure analysis showed that the martensite and residual austenite phases in the raw material transformed into pearlite and ferrite phases after the annealing process. This phase transformation affects the mechanical properties, particularly reducing the material's hardness from an average of 54.76 HRC to 48.73 HRC. This decrease in hardness is attributed to the dominance of the soft ferrite phase.
