Marine 1.4418 Stainless Steel Soft Martensitic Chromium Nickel Molybdenum
1.4418 Soft Martensitic Chromium-Nickel-Molybdenum Stainless Steel
1.4418 is characterised by its very good resistance to corrosion in aggressive media coupled with very good mechanical and impact properties.
1.4418 is specifically designed to combine high mechanical strength and toughness, with improved corrosion resistance compared to the traditional martensitic and martensitic precipitation grades. This grade exhibits very good erosion-corrosion resistance or cavitation encountered in hydraulic or flow applications as well as excellent properties in elevated and cryogenic temperatures.
