Heat Treatment Services at Hexagon Metals

At Hexagon Metals, we provide advanced heat treatment services designed to enhance the mechanical properties, durability, and performance of castings, forgings, and machined components.

Our controlled heat treatment processes improve strength, hardness, ductility, wear resistance, and dimensional stability—ensuring your parts meet the demanding requirements of industrial applications.

Our Heat Treatment Services

Every process is carried out in temperature-controlled furnaces operated by trained metallurgical technicians following ASTM, AMS, and NADCAP-aligned procedures.

Annealing (Solution Anneal / Furnace Cooling)

Annealing is used to soften metals, improve ductility, and relieve residual stresses after casting, forging, or machining.

Applications: Heat relief for cast steel and stainless steel components, improving formability for machining or shaping, preparing aluminum parts for further heat treatment, restoring ductility after cold working, etc.

Industries Served: Aerospace & defense, oil & gas, automotive & EV components, power generation, and heavy machinery & industrial equipment, etc.

Materials Treated: Carbon and alloy steels, stainless steels, aluminum alloys (solution anneal), copper, and brass, etc.

Normalizing for Cast and Forged Components

Normalizing improves mechanical strength, grain structure, and toughness—especially useful for forged or cast components requiring uniformity.

Applications: Structural steel parts, gears, shafts, high-load components, pressurized and load-bearing parts, and alloy steel castings & forgings, etc.

Industries Served: Construction equipment, rail & transportation, automotive powertrain, oilfield tools, and heavy industrial machinery, etc.

Materials Treated: Carbon steel (1018, 1045, etc.), alloy steel (4140, 4340, 8620), and tool steels, etc.

Hardening (Heat Hardening)

Hardening increases strength and wear resistance by heating metal to its critical temperature followed by controlled cooling.

Applications: Wear-resistant mechanical parts, gears, cams, levers, bearings, tools and dies, and heavy-duty structural components, etc.

Industries Served: Mining & construction, automotive & heavy truck, aerospace (non-critical steel parts), and oil & gas drilling equipment, etc.

Materials Treated: Alloy steels, carbon steels, and tool steels, etc.

Quenching

Quenching rapidly cools heated metals to achieve high hardness and improved mechanical strength.

Quenching Options: Water quench, oil quench, polymer quench, and air quench, etc.

Applications: High strength hydraulic parts, shafts and axles, forged parts requiring surface hardness, precision components needing high fatigue resistance, etc.

Industries Served: Oil & gas, automotive, power transmission & gears, and construction & mining, etc.

Materials Treated: Alloy and carbon steels, stainless steels, and tool steels, etc.

Tempering

Tempering reduces brittleness after quenching while maintaining strength and hardness.

Applications: Heat treated castings and forgings, structural load-bearing parts, shafts, gears, mechanical components, tooling, and impact-resistant parts, etc.

Industries Served: Heavy machinery, automotive powertrain, defense equipment, and industrial equipment manufacturing, etc.

Materials Treated: Steel and alloy steel, and heat treated components requiring stress relief, etc.

Aluminum Heat Treatment (T5, T6, T7)

We specialize in aluminum heat treatment for cast, extruded, and machined components to enhance strength, hardness, and dimensional stability.

T5 Heat Treatment: Artificial aging after casting or extrusion for moderate strength improvement.

T6 Heat Treatment: Solution heat treatment followed by artificial aging to maximize strength and performance; the most common treatment for cast aluminum parts.

T7 Heat Treatment: Stabilizes components for high-temperature applications while improving dimensional stability.

Applications: Automotive housings and suspension parts, aerospace aluminum components, electronic enclosures and heat sinks, precision machined aluminum components, compressor and pump components, etc.

Industries Served: Aerospace & aviation, automotive & electric vehicle, electronics & semiconductor, renewable energy, and marine & offshore, etc.

Materials Treated: Aluminum alloys including A356, 6061, 7075, 319, 380, and related grades, etc.
