Mar 28, 2020nbsp018332grade b8 stud bolts are made of aisi 304 stainless steel. these type of fasteners are made with austenitic stainless steel and require carbide solution treatment. the carbide solution treatment, also known as solution annealing, is the process in which fasteners are heated and then water-quenched to assure maximum corrosion resistance.
In normal conditions, austenitic stainless steels are given a high-temperature heat-treatment, often called a solution-treatment, which gives a fully austenitic solid solution.however, at temperatures below about 800176c, there is a tendency to precipitate chromium-rich carbides as the alloy enters the carbide plus austenite phase field.
Ntks carbide series offers a variety of coated insert grades which have been developed to improve their resistance characteristics, including wear, fracture, adhesion, oxidation and the like, by utilizing our state-of-the-art technology.
In fact, this is a one-sided wrong view of the lack of understanding of stainless steel. stainless steel will rust under certain conditions. stainless steel has the ability to resist atmospheric oxidation, that is, stainless steel has the ability of corrosion resistance in the medium containing acid, alkali and salt, namely corrosion resistance.

Unlike soft metal steel welding wires which are commonly used with the mig carbide embedding process, the high hardness tool steel micro-structure of postalloy174 ps-98 matrix is designed to encapsulate and protect the carbide particles from premature erosion. use on carbon, low alloy steel and manganese steel.
These taps are solid carbide with an aluminum-titanium-nitride altin coating for high strength and excellent wear resistance. use them on hard and abrasive material, such as heat-treated metal, nickel, and fiberglass. the extreme hardness of carbide taps means they are brittle, so theyre not recommended for hand tapping. a highly rigid setup, such as a cnc machine, is necessary to prevent ...
Found that during austenitization the average radius of carbide particles increases quickly as small carbide particles dissolve in the austenite, but increases only slowly once small particles have disappeared. the nearly constant carbide radius maintained after the disappearance of small ... 1.1 the history of stainless steel cutting ...
