Martensitic Free-Machining Grade · Sulfur Enhanced · High Hardness & Precision Surface Finish · Global Supply
HRS Ferritic specializes in ferritic, martensitic and stainless steel products. As a trusted SS 416 Sheet Supplier and SS 416 Sheet Importer, we maintain strong partnerships with ISO-certified and ASTM-certified mills to ensure consistent quality, traceability and compliance with international standards.
A martensitic free-machining stainless steel with sulfur inclusions that reduce friction between cutting tool and material. Allows for faster machining, reduced tool wear and better dimensional accuracy. Heat-treated SS 416 gains increased strength and hardness, ideal for wear-resistant and load-bearing components.
Each element in SS 416 plays a precise role in delivering exceptional machinability and mechanical performance.
