Kobs India is a manufacturer, exporter and stockist of Hastelloy Buttweld End Cap Pipe Fittings. These fittings are offered in customizable sizes as per the client requirements. ASME SB366 Hastelloy UNS N06022 Pipe End Cap helps with giving less frictional resistance to the fluids compared to other fittings. One of its great features is excellent weldability and resistance to crevice corrosion. ASTM B336 Hastelloy UNS N10276 Buttweld End Cap Fittings are fittings that give good resistance to reducing and oxidising aqueous media.
ASME SB 336 Hastelloy B2 Buttweld End Cap is less susceptible to stress and crevice corrosion. It can be used in the welded condition. ASTM B 564 Hastelloy X Buttweld Fittings is used in aircrafts, furnaces and chemical processes. ASTM B 564 Hastelloy C276 Buttweld Pipe Fittings is resistant to the formation of grain boundary precipitates in the weld heat-affected zone. It exhibits good formability, weldability and machinability.

The principal methods of hot working are extrusion, drawing, forging and rolling. Rolling is the most extensive employed forming process, though some limitations may apply to the process. Rolling mainly consists of three major sub-categories: flat rolling, shape rolling (with specifically designed roll grooves) and pipe rolling (including piercing). Forging may be sub-categorized as hamming, pressing, etc. .
Forging may be performed under hammers, in mechanical presses and upsetters or by a method known as roll forging. Pressing generally includes the manufacture of forged articles in hydraulic presses. Extrusion usually is performed in hydraulic presses which force the hot steel through a die. Rolling is performed in rolling mills of a variety of types. .
The two principal reasons for perform metal forming at elevated temperatures (hot working) are to reduce the forming loads through the reduction of the resistance of the steel to deformation, and to develop preferred metallurgical structures for strength and ductility of the finish products.
The most appropriate manufacturing method of a product will be decided with consideration of its material, sizes, shape, use, standards and other properties.
