16MnCr5 (1.7131) Alloy Steel
16MnCr5 steel is a low-alloy carburizing steel widely used for engineering and automotive applications requiring excellent surface hardness, wear resistance, and core toughness. Known as DIN 1.7131 steel, 16MnCr5 alloy steel is specifically designed for case hardening processes, making it ideal for parts exposed to friction, repeated stress, and heavy mechanical loads.
16MnCr5 steel round bar is commonly used for gears, shafts, pinions, and transmission components. Due to its excellent hardenability and machining performance, 16MnCr5 alloy steel bar provides reliable performance in high-load industrial environments.
Compared with standard carbon steels, 16MnCr5 steel offers improved wear resistance, better fatigue strength, and superior surface hardness after carburizing. This makes 16MnCr5 round bar a preferred material for precision-engineered mechanical parts.
