Sensitization refers to the susceptibility of materials to intergranular corrosion and comes about by a combination of factors in the materials composition and treatment.
Contributing factors can include heating and cooling through specific temperature ranges, increased C content or decreased Cr content and among other factors.
The continuous focus on weight reduction in the automotive industry demands thinner materials with compromising key factors such as performance and safety.
Dent resistant steels can be classified into non bake-hardenable and bake-hardenable groups or Type A and Type B respectively as classified by SAE.
Also known as the Oxygen Flash Cyclone Electro Thermal Process, the KIVCET Smelting Process was first developed in Kazakhstan with the first commercial unit being installed in 1985.
The Kivcet lead process has been specially developed for complex ores with high zinc contents and some of the key advantages include no requirement for sintering, single stage process, autogenous smelting among others.
Sacrificial anodes are specifically designed to act as corrosion ‘decoys’ for materials which require protection from a variety of corrosive forces.
Typically with more negative electrochemical potential sacrificial anodes for steel can include zinc, aluminum and magnesium based on their position in the galvanic series.
High silicon materials are classified as having a silicon content above r14.5% and as a result provide excellent corrosion resistance with good properties and cost savings on the nobles metals such as nickel and chromium.
Some examples of the technological characteristics include good castability, due to low melting points and small solidification temperature intervals.
