34CrNiMo6+QT Alloy Structure Steel Bar Rod Annealed OD 55mm 6M Length
34CrNiMo6+QT Alloy Steel Bar DIN 1.6582 Alloy Structure Steel Rod OD 55mm 6M Length
34CrNiMo6 Steel is a typical high-strength alloy structural steel in the European standard. As a medium carbon alloy steel containing Molybdenum, Chromium and Nickel,it is considered to be one of the most popular steels in Europe.
In the quenched and tempered condition, the performance characteristics of 34CrNiMo6 steel can be maximized,that is, High Strength, High Toughness and Good Hardenability.This is why you will find this type of steel often used in high strength requirements in European countries.
Due to its excellent comprehensive mechanical properties,34CrNiMo6 steel is widely used in the manufacture of important parts such as train axles, mechanical main shaft parts, wind power shafts, engine camshafts and connecting rods,etc.
