1144 Stress-proof equivalent in Europe?

[DiegoVV]

Hi fellow members,

For the crankshaft of my next project (An Offy 270), the plans asks for 1144 to make the crankshaft. I understand that this steel combines great machineability with low internal stress that will help in keeping it straight when removing large amounts of material.

The problem is that I don´t seem to find the equivalence of 1144 in the European standards. Does any colleague from the old side of the world have any suggestion?

Thank you all!

The European equivalent of 1144 stress proof steel is typically considered to be EN 10088: 44SMn28 under the European standard, which is a steel grade with similar properties to 1144 steel, particularly its high strength and good ductility.
