30MnB5
General Information
Grade SB33M13B is a boron steel for general purposes without any specified mechanical properties. Its
closest equivalent is found in the EN10083-3:2006 grade 30MnB5. The difference is the carbon and
chromium content.
SB33M13B may serve as wear parts in for example graders and snow ploughs but also suitable for
agriculture machinery.

To get the full picture of our products environmental impact we have to look at all of our CO2 emission
sources.
Not only the steel work Scope 1-2 itself, but all operations downstream in our production, heating and
heat treatment furnaces etc (full scope 1-2) as well as all the emission from input material, eg. alloys,
