Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Alloy 20 Tubes, which are trusted for their various salient features like corrosion resistance, durability and high tensile strength. Our Alloy 20 Seamless Tubes is steel that is alloyed with a variety of elements in total amounts between 1.0 % and 50 % by weight to improve its mechanical properties. The simplest steels like these Alloy 20 Welded Tubes are iron (Fe) alloyed with carbon (C) (about 0.1 % to 1 %, depending on type). Our Alloy 20 EFW Tubes is a metal alloy consisting mostly of iron, in addition to small amounts of carbon, depending on the grade and quality of the steel.
These Alloy 20 ERW Tube are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and Aluminium. The process of making our Alloy 20 Round Tube is highly specialized and complex, which contains niobium for stabilization against sensitization and resultant inter – granular corrosion. These Alloy 20 Square Tubes contain specified amounts of alloying elements — other than carbon and the commonly accepted amounts of manganese, copper, silicon, Sulphur, and phosphorus.
Our Alloy 20 Rectangular Tubes is tailor-made as per the customer’s specification and end application. These Alloy 20 Electropolish Tubes is any type of steel to which one or more elements besides carbon have been intentionally added, to produce a desired physical property or characteristic.
