UGI® 4462 Solution Annealed Turned Bar

UGI® 4462 Solution Annealed Turned Bar introduction

Duplex stainless steel with high corrosion resistance and high mechanical performances, UGI® 4462 has excellent corrosion resistance in aggressive environments, coupled with high mechanical properties.

The chemical composition of UGI® 4462 is optimised to obtain, after a solution annealing heat treatment, a two-phase ferrite + austenite structure containing between 40% and 60% ferrite.The UGI® 4462 grade is sensitive to precipitation of inter-metallic phases which degrade the mechanical properties and corrosion resistance. The sigma phase (σ) precipitates between 600°C and 1000°C, after a holding time of a few dozen minutes.The precipitation phase α' between 350°C and 550°C also presents a risk of embrittlement. Consequently the temperature at which the grade is used must be limited to 300°C (see the charts on the right side of the material page).
