Introduction
Stainless steel grade Duplex 2101 LDX is a low-alloyed, general-purpose duplex. This steel possesses high tensile strength as well as high fatigue strength. Its high mechanical strength is same as other duplex grades, and its good corrosion resistance is equal to most standard stainless steel grades. All these properties are utilized to design products with strength, low maintenance, durability and long-term cost efficiency.
The following datasheet provides an overview of stainless steel grade Duplex 2101 LDX.
