Annealing
Annealing
Softening, Spheroidizing & Peak Machinability Conditioning
Full annealing, isothermal annealing, and spheroidize annealing heat the material to specific temperatures followed by slow, controlled furnace cooling to achieve lowest hardness, high ductility, and optimal microstructures.
Key Specifications
Maximum Ductility & Spheroidized Carbide Distribution
Particularly vital for high-carbon tool steels (D2, D3, H13) and bearing steels (SAE 52100) to form globular spheroidized carbides, allowing high-speed machining and cold forming without tool breakage.
Applications & Alloy Grades
Essential step for cold heading wires, stamping blanks, and tool blocks.
Tool & Die Steel Stock
D2, O1, H13, and P20 blocks softened for CNC milling and EDM wire-cutting.
Bearing Steel Rings & Wire
SAE 52100 spheroidized rings for cold rolling and seamless turning.
Cold Forging Preforms
Bolt blanks, extrusion slugs, and fastener wire coils.
Cast Iron & Ductile Iron Castings
Graphitizing annealing for improved impact toughness and machinability.
Brinell Hardness Mapping & Spheroidization Rating
Multi-point Brinell hardness testing and ASTM spheroidization percentage verification ensure effortless tool chip formation and prolonged cutting tool life.
