Differences:
Minor differences in chemical composition;
Different standard nomenclature (AFNOR and DIN standards).
Advantages of use:Both materials have a wide range of applications in the field of mechanical engineering, especially in the manufacture of parts with high strength, high toughness, and high wear resistance requirements.
How to choose:
Standard Requirements:Choose materials that meet your requirements based on the standards and specifications of your region. If you follow a specific international standard, you can choose the corresponding 16850 or 16582。
Application Requirements:Consider the specific requirements of your part, such as strength, toughness, wear resistance, etc. The material is selected based on these properties.
Processability:If machining is required, such as forging, quenching, tempering, etc., consider the processing properties of the material to ensure that the desired mechanical properties are obtained. 34crnimo6 gear steelSummary:1.6850 and 16582 is an excellent low-alloy steel with similar properties, so when it comes to actual selection, it can be decided based on the standards of your region and the requirements of your specific application. It's a good idea to consult with a materials engineer or professional before making a choice to ensure that the material you choose meets your specific needs.
