RG-2400 STOPS CORROSION	GLOSSARY OF CORROSION RELATED TERMS
RG-2400 will STOP existing corrosion and will prevent corrosion on new piping systems. Minimal surface preparation is required.

	Q
	QUENCH-AGE EMBRITTLEMENT	Embrittlement of low-carbon steels resulting from precipitation of solute carbon at existing dislocations and from precipitation hardening of the steel caused by differences in the solid solubility of carbon in ferrite at different temperatures. Quench-age embrittlement usually is caused by rapid cooling of the steel from temperatures slightly below Ac, (the temperature at which austenite begins to form), and can be minimized by quenching from lower temperatures.
	QUENCH AGING	Aging induced by rapid cooling after solution heat treatment.
	QUENCH CRACKING	Fracture of a metal during quenching from elevated temperature. Most frequently observed in hardened carbon steel, alloy steel, or tool steel parts of high hardness and low toughness. Cracks often emanate from fillets, holes, corners, or other stress raisers and result from high stresses due to the volume changes accompanying transformation to martensite.
	QUENCH HARDENING	(1) Hardening suitable alloys (most often certain copper or titanium alloys) by solution treating and quenching to develop a martensite-like structure. (2) In ferrous alloys, hardening by austenitizing and then cooling at a rate such that a substantial amount of austenite transforms to martensite.
	QUENCHING	Rapid cooling of metals (often steels) from a suitable elevated temperature. This generally is accomplished by immersion in water, oil, polymer solution, or salt, although forced air is sometimes used.
