What is the equivalent grade of 16Mo3 steel

16Mo3 is a type of low-alloy steel with high temperature properties, also known as EN 10028-2 16Mo3. It has a carbon content of 0.12-0.20% and a molybdenum content of 0.25-0.35%. This alloy steel is commonly used in power plants, boilers, and pressure vessels due to its excellent heat resistance, high temperature strength, and good weldability.

The tensile strength of 16Mo3 steel is 440-590 MPa, and its yield strength is 220-275 MPa. Its elongation at break is 22% and its impact strength at room temperature is 20 Joules. The steel can withstand temperatures up to 600°C, making it suitable for use in high-temperature applications.

In terms of its composition, 16Mo3 steel is similar to ASTM A204 Gr. B and DIN 17155 15Mo3 steel. However, it has its own unique properties and applications, and it is important to consult with a professional before using this steel in a particular application.

The equivalent grade of 16Mo3 steel varies depending on the standard used. Some of the commonly used equivalents of 16Mo3 steel are:

ASTM A204 Grade B

EN 10028-2 15Mo3

DIN 17155 15Mo3

BS 1501-243B

JIS G3103 SB410

It is important to note that while these grades are similar in composition and properties, they may have some differences in terms of their specific requirements, such as testing methods or maximum allowable stress levels. Therefore, it is important to check the specific requirements for your application and consult with a professional before selecting a particular equivalent grade of 16Mo3 steel.
