Hardening
HARDENING (2250°F max)

  Hardening via water-quench, oil-quench, forced- or still-air quench, or aging results in improved mechanical properties, hardness, and toughness of the alloy material.

Water Quench (Up to 2250°F) & Tempering (350 - 1200°F):
This process is applied to water-hardening medium carbon and low carbon alloy grades of steel for improved strength, hardness, and toughness in light to moderate sections sizes.

Oil Quench (Up to 2250°F) & Tempering (350 - 1200°F):
This process is applied to oil-hardening medium-to-high carbon and medium-to-high carbon alloy grades of steel for improved strength, hardness, and toughness in moderate to heavy section sizes.

Forced-Air Quench (Up to 2250°F) & Tempering (350 - 1200°F):
This process is applied to medium carbon low alloy grades of steel for improved strength, hardness, and toughness with reduced risk of distortion.

Still-Air Quench (Up to 2250°F) & Temper (350 - 1200°F):
This process is applied to air-hardening grades of steel for improved strength, hardness, and toughness with reduced risk of distortion.

Age Hardening (300 - 1400°F):
This process is applied to age-hardenable, or precipitation - hardenable ferrous and nonferrous alloys for improved strength, hardness, and toughness with reduced risk of distortion.
