Quenching
QUENCHING (2250°F max)

  Quenching is an integral part of hardening via water-quench, oil-quench, forced- or still-air quench,solution anneal and age, resulting in improved mechanical properties, hardness, and toughness of the alloy material.

Water Quench (Up to 2250°F) & Tempering (350 - 1200°F):
  Water quenching 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. This treatment is also used in solution annealing of various ferrous and nonferrous alloys for improved corrosion resistance, or as a precursor to precipitation or age hardening.

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. This treatment is also used in solution annealing of various ferrous and nonferrous alloys for improved corrosion resistance, or as a precursor to precipitation or age hardening.

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. This treatment is also used in solution annealing of various ferrous and nonferrous alloys for improved corrosion resistance, or as a precursor to precipitation or age hardening.

Selective Quench (Up to 2250°F):
  Selective quench is applied to parts requiring a select area to be hardened without affecting the remainder of the part.

Time-Controlled Quench (Up to 2250°F):
   Time-controlled quench is sometimes applied to crack sensitive parts. This process comprises parts being quenched in a fast quenching medium for a given time period before being quenched in a slower quench medium to avoid cracking while maintaining maximum hardness.
