What is 15Mo3 equivalent to?

15mo3 material is used in applications with elevated temperatures like heat exchangers and pressure vessels, and they are equivalent to UNI5869 15Mo3 and EN10028 16Mo3, ASTM A204Gr. B and 15D3 (NFA 36205 ). The 1.5415 material comes with excellent heat resistance and corrosion resistance.

 

What is 15Mo3 material?

The 15Mo3 steel tube is a low-alloy steel that contains 0.3% molybdenum and 1.25% chromium. The addition of these two elements improves the steel's strength, resistance to corrosion, and high-temperature performance. The chemical composition of 15Mo3 steel tube is as follows:

Element

Chemical Composition (%)

Carbon

0.12 – 0.20

Silicon

0.35 max

Manganese

0.40 – 0.90

Phosphorus

0.025 max

Sulfur

0.010 max

Chromium

0.30 – 0.70

Molybdenum

0.25 – 0.35

 

What is din 15Mo3 equivalent to?

DIN 15Mo3 is EN 16Mo3 equivalent grade. It is easy to note that the chemical composition and mechanical properties of 16Mo3 steel and EN 16Mo3 equivalent grade DIN 15Mo3 are almost the same. They are perfectly equivalent to each other.
