Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Alloy Steel 20 Nipple, which provides highly safe and reliable operations. Our Alloy 20 Hexagon Reducing Nipple is steel that is alloyed with a variety of elements in total amounts between 1 % and 50 % by weight to improve its mechanical or physical properties. Alloying elements of this Alloy 20 Hexagon Nipple are added to achieve certain properties in the material. As a guideline, alloying elements of our Alloy 20 One End Threaded Nipple are added in lower percentages (less than 5 %) to increase strength or hardenability.
Alloying elements of this Alloy 20 Both End Threaded Nipple are also added in larger percentages (over 5 %) to achieve special properties, such as corrosion resistance or extreme temperature stability. Also the alloying elements of our Alloy 20 Concentric Swaged Nipple tend to form carbides or compounds, rather than simply being uniformly mixed in with the iron and carbon. Nickel, Aluminium, and silicon are examples of the elements that form compounds in this Alloy 20 Eccentric Swaged Nipple.
Few exact rules exist for selecting through – hardening or surface – hardening grades of our Alloy 20 Hex Nipple. In most cases, critical parts of this Carpenter 20 Hexagon Reducing Nipple are field tested to evaluate their performance. Our Carpenter 20 Hexagon Nipple is often specified when high strength is needed in moderate – to – large sections.
