The specially designed Carbon content allows Tri-Braze® to be heat treated to a high hardness while still remaining readily weldable.
The Manganese content enhances the hardness and hardenability of the steel while promoting the ductility.
The very low Phosphorous and Sulfur contents make for a very clean steel and greatly enhance the toughness. Because Tri-Braze® is specially treated for sulfide shape control, any sulfide or oxide inclusions inherent in the steel will be limited, microscopically small, and globular in shape. This in turn means a more homogeneous material with more uniform properties in the longitudinal, transverse and thru-thickness directions.
The Silicon content provides adequate deoxidation and assures a fully killed steel.
Chromium and Molybdenum promote hardenability (the depth of hardness), enhance the atmospheric corrosion resistance, and increase high temperature properties.
The Nickel addition adds to the strength and toughness but is used sparingly in order to reduce the difficulties of rolled in scale thereby producing a smoother plate surface.
Titanium benefits the Boron by combining with the nitrogen, thereby allowing the Boron addition to be effective. It also promotes grain refinement, imparts temper resistance, and forms a very hard complex Titanium Carbo-Nitride for better wear resistance. The Boron is used to intensify the hardenability. A very small amount of Boron is required for a marked increase in the hardenability. Boron treated steels generally possess better hot and cold working characteristics than other alloy steels having equal or higher hardenability.
Aluminum acts as a deoxidizer and for control of inherent grain size.
