Application
It is used in taps, ejector pins, gauges, roller bearings, and swaging dies. It is an excellent alloy steel for put in resisting machine elements and for press gears which do not require an extra complex quality.
Conclusion
EN31 steel is an alloy steel, which is a versatile high-carbon steel with a good balance of hardness, strength, and wear resistance with reasonable toughness. Due to these exceptional uses, it is preferred to perform widely in engineering fields like bearings, automobile parts, stainless knives, and endurance-laden machine components. In substantive operating conditions, EN31 is extremely serviceable, and it comes in a myriad of different forms. It is one of the most reliable materials in use today in conditions that require strong and accurate materials, and is a material that industries trust.
