Kencotube is specialized in manufacturing Alloy Steel Flanges, which is alloyed with a variety of elements in total amounts between 1.0 percent and 50 percent by weight to improve its mechanical or physical properties. Alloying elements are added to achieve certain properties in Alloy Steel Pipe Flanges, whereas a guideline, alloying elements are added in lower percentages (less than 5 percent) to increase strength or hardenability, or in larger percentages (over 5 percent) to achieve special properties, such as corrosion resistance or extreme temperature stability. In Alloy Steel Slip On Flanges, the alloying elements tend to form carbides or compounds, rather than simply being uniformly mixed in with the iron and carbon, where nickel, aluminium, and silicon are examples of the elements that form compounds in the steel.
Few exact rules exist for selecting through-hardening or surface-hardening grades of Alloy Steel Blind Raise Face Flanges, where in most cases critical parts are field tested to evaluate their performance. Alloy Steel Weld Neck Raised Flanges are often specified when high strength is needed in moderate-to-large sections, where tungsten and vanadium will form carbides, both of which increase the hardness and stability of the finished product. Parts with large sections — heavy forgings, are often made from Alloy Steel Long Weld Neck Flanges that have been vacuum degassed. While in a molten state, these Alloy Steel Lap Joint Flanges are exposed to a vacuum which removes hydrogen and, to a lesser degree, oxygen and nitrogen.
