Product Description
High-Performance Chromium-Nickel-Molybdenum Alloy Steel
36NiCrMo16, 1.6773, 35NCD16, 30NCD16, 30NiCrMo16, and 1.6747 are premium chromium-nickel-molybdenum alloy construction steels engineered for the most demanding applications in heavy-duty machinery, industrial equipment, and aerospace components.
Material Advantages
These alloy steels feature significantly higher nickel content compared to standard grades, delivering superior tensile strength, yield point performance, and exceptional hardenability. They provide outstanding resistance to impact, deformation, wear, and operational stresses.
Grade Variations
30NiCrMo16 / 1.6747 contains lower carbon content for specific applications. 35NiCrMo16 / 1.2766 is classified as tool steel and is commonly used for specialized cutting tools and plastic injection molds.
