Ein nichtrostender Vergütungsstahl mit hohen Festigkeits- und Zähigkeitswerten für den Maschinen- und Apparatebau

A martensitic stainless steel with high strength and impact properties for chemical and mechanical engineering purposes Within the last few years the low carbon martensitic stainless steel X4CrNiMo 165, WNr. 1.4418, is increasingly used due to it's excellent technological properties. The steel can he offered with tensile strength up to 850 N/mm² and yield strength up to 1000 N/mm² together with superior impact properties at room temperature and sub-zero-temperature. So this steel has special significance concerning chemical engineering, where corrosion resistance as well as high tensile and impact values are demanded. There is no selective corrosion attack in boiling sulfuric acid (Strauß-Test), if the material is quenched and tempered correctly. Welding operations may be done without preheating the material.
