Heat Treating Steel - Hardening and Tempering

For high carbon and alloy steels annealing requires cooling in a furnace that has temperature controls so that the rate of cooling is no more than ~20°F/hr. Non-ferrous metals such as aluminium, brass, copper and silver are annealed by heating to a low red and quenching in water (the opposite of steel)....<<more>>

Stainless Steel - High Temperature Resistance

A further property that can be relevant in high temperature applications is the thermal expansion of the particular material. The coefficient of thermal expansion is expressed in units of proportional change of length for each degree increase in temperature, usually x10 -6 /°C, μm/m/°C, or x10 -6 cm/cm/°C, all of which are identical units....<<more>>
