About alloy 20-
Alloy 20 that is commonly known as UNS N08020 is the austenitic, chromium, nickel, iron-based superalloy along with the addition of alloys like molybdenum and copper. This is to provide the resistance to pitting, hostile atmosphere and crevice corrosion. Also, this alloy is stabilized with the columbium for minimizing the carbide precipitation at the time of welding. Alloy 20 seems to be falling in between the nickel and stainless categories as it is having properties of both alloying elements. It is developed for maximum resistance to acid attacks and is also demonstrating the excellent stress corrosion cracking resistance at the boiling 20% to 40% sulfuric acid. It is also having very good general corrosion resistance ability at sulfuric acid and to the chloride stress corrosion cracking. Alloy 20 is having very good mechanical properties at ambient temperature and elevated temperature ranging 500 Deg C and it is fabricated readily through the industrial process. .
About the product manufacturing-
The production process of Alloy 20 Fasteners at our highly operational manufacturing unit is done with the help of available latest technology and modern tools. We are developing the ranges of fasteners by using the premium quality of alloy that is well tested and quality assured. We are only collecting raw material from the reliable market vendors that are 100% pure. During the time of product development, we are considering several raw material quality standards to assure that national and international product quality standards are well maintained. We have hired the team of professionals that are guiding the workforce for the development of fine quality of fasteners. The quality checker team is also there that are looking at the quality maintenance of the fasteners and are checking it according to quality control norm. Thus we are able to offer the high quality of fasteners to the buyers as per their expectations.
Qualities of the fasteners-
Alloy 20 Fasteners is having numbers of good qualities to offer because of which it has become an ideal choice for various critical applications and elevated temperature atmosphere. The properties that the fasteners have got are because of the addition of alloying elements in the right proportion during the time of fasteners creation. Some properties possessed by it is-
• High tensile strength
• Good mechanical properties
• Rugged construction
• Pitting/oxidation resistance
• Stress corrosion cracking resistance
• General corrosion resistance
• Holds high temperature
• Holds greater pressure
• High hardness
To assure about the product quality we are conducting several testing on Alloy 20 Fasteners. The testing is the PMI test, IGC test, hardness test, macro test, micro test, chemical test, mechanical test, pitting resistance test, etc.
Some documents we provide to the buyer are fumigation certifications, commercial invoice, packaging list, raw material traceability report, guarantee letter, NABL approved lab test report, material traceability report, etc. Also, certain test certifications we provide are mill test certifications according to En 10204/3.1b, 100% radiography test report, third-party inspection report and buyers report, etc.
