D = Diameter of the round bar.

S = Distance between two parallel sides for square and hexagonal bar, thickness for rectangular bar

For materials with a thickness of 20 mm or more, refer to EN 755-1 for stress corrosion cracking resistance If the cross-sectional area of a profile has different thicknesses and these different thicknesses have more than one specified mechanical corresponds to the properties, then the lowest specified value for the cross-sectional area of the whole profile should be taken.

CHARACTERISTIC FEATURES

It is one of the alloys with the highest hardness among alloy groups. It can be used in areas where high hardness and strength are required.

PRODUCTION TYPES

It is possible to produce for varieties such as plate, lama, solid bar.

AREAS OF USE

It is used in mold making, nuclear applications, ski poles, defense industry, machine parts, rail systems.
