heat treatment and high chrome iron

Heat treating

Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and elasticity...

Heat Resistant Castings

Heat Resistant Castings-Iron Base Alloys Castings are classified as heat resistant if they are capable of sustained operation while exposed, either continuously or intermittently to operating temperatures that result in metal temperature in excess of 650°C (1200°F) Alloys used in castings for such applications fall into four broad categories ....

MICROSTRUCTURE AND EROSION

Microstructure and erosion-corrosion behaviour of as-cast high chromium white irons containing molybdenum in aqueous sulfuric-acid slurry was studied The experimental irons contained 28 wt%Cr with a Cr:C ratio of about 10 and up to 10 wt%Mo The irons with up to 6 wt%Mo are hypoeutectic, whereas the iron with 10 wt%Mo becomes eutectic ....

Heat Treatment of Cast Irons

form iron is lustrous, silvery, soft, and ductile However, pure iron is a poor engineering material, generally not as strong as most plastics Cast irons are based on the Fe-C system, and the solid-state transformations on which cast iron heat treatments are based are similar to those applied to steels Heat Treatment of Cast Irons...

Passivation (chemistry)

Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air...
