Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels, stainless steels, and duplex stainless steel.
304L is a low-carbon austenitic chromium-nickel steel designed for special applications. [30] 316L is a low carbon austenitic chromium-nickel steel with superior corrosion and heat resisting qualities. [31] 321 is an austenitic chromium-nickel steel with a high chromium content of 18.00%. [32] 400 series
Steel castings after undergoing 12-hour 1,200 °C (2,190 °F) heat treatment. Complex heat treating schedules, or "cycles", are often devised by metallurgists to optimize an alloy's mechanical properties. In the aerospace industry, a superalloy may undergo five or more different heat treating operations to develop the desired properties.
Further excessive heat-treatment brings about the decomposition of the martensite and reversion to austenite. Newer compositions of maraging steels have revealed other intermetallic stoichiometries and crystallographic relationships with the parent martensite, including rhombohedral and massive complex Ni 50 (X,Y,Z) 50 (Ni 50 M 50 in simplified ...

Differential heat treatment is a method used to alter the properties of various parts of a steel object differently, producing areas that are harder or softer than others. This creates greater toughness in the parts of the object where it is needed, such as the tang or spine of a sword, but produces greater hardness at the edge or other areas ...
An electric fan or a box bellow is used to feed air into the forge. The steel is usually one of the carbon knife steels Hitachi produces at Yasugi Specialty Steel. These are the unalloyed White steel (1, 2, 3) and the tungsten and chromium alloyed Blue steel (1, 2, Super), with White 2 the most common and Blue 2 the next most produced.
