is a high-carbon steel which is suitable for hard wearing applications which are not sufficiently severe to warrant more sophisticated steels. This material is used for liner plates and scraper blades, preferably fitted by drilling and bolting.
0.4% - 0.55% C, 0.7% - 1.0% Mn, 0.15% - 0.35% Si
+- 200 BHN. (Not measured or guaranteed).
May be cut with pre-heating recommended for thicker sections.
is a difficult steel to weld due to its high carbon equivalent.
Welding should be used for joining purposes only and is not recommended under high stress conditions.
Hydrogen controlled electrodes should be used with a minimum preheat of 250oC. For austenitic electrodes, use a minimum preheat of 150oC. Cooling rates after welding should be controlled.
can be sheared in thicknesses up to 25 mm, provided sufficient power is available. Cutting edges must be sharp and clearances set correctly.
up to 12 mm can be punched provided tools are sharp and clearances are set correctly.
