Free-Machining Martensitic Grade · Sulfur Enhanced · High Strength & Precision Machinability · Global Supply
HRS Ferritic, a global leader in stainless steel solutions, is a trusted AISI 416 Plate supplier, SS 416 Plate stockist and SS 416 Plate importer. SS 416 is a martensitic grade of stainless steel with improved machinability thanks to an added sulfur content, combining high strength and corrosion resistance with ease of machining for precision industrial components.
The martensitic structure and sulfur-enhanced machinability of SS 416 make it exceptionally efficient for precision components. Carbon and chromium combine to form a passive oxide on the surface for corrosion resistance, while sulfur improves machinability for complex shaping, drilling and cutting in both moderately and mildly corrosive environments.
Each element in SS 416 plays a precise role in delivering the exceptional machinability, strength and moderate corrosion resistance this grade is known for.
