At Mitchell Stainless in Hamilton, New Zealand, we supply premium stainless steel sheets and plates engineered for strength, wear resistance, and moderate corrosion resistance. Our SS 418 Sheets and Plates are martensitic stainless steel, offering high hardness, tensile strength, and durability, making them ideal for industrial and structural applications. Designed to perform under mechanical stress and moderate corrosive conditions, these sheets and plates deliver reliable long-term performance. Supported by Mitchell Stainless’ commitment to quality and local expertise, SS 418 Sheets and Plates provide strong, wear-resistant, and dependable solutions for demanding engineering, industrial, and structural projects.
SS 418 Sheets and Plates are manufactured from a martensitic stainless steel alloy containing chromium and carbon. This composition provides excellent hardness, tensile strength, and wear resistance while maintaining moderate corrosion protection. The material can be heat-treated to enhance mechanical properties, delivering superior durability under stress. SS 418 maintains dimensional stability and mechanical integrity in demanding applications. Its combination of toughness, hardness, and resistance to wear makes it suitable for industrial and structural applications requiring reliable and long-lasting stainless steel components.
