Steelo Fabrica manufactures the Alloy 20 Round Bar, which are an austenitic, nickel-iron chromium-based superalloy. These bars are manufactured in customized and defaults forms. We also provide different specifications with our bars.
The material combination of Alloy 20 Round Bar:
The Alloy 20 Round Bars are manufactured with nickel, chromium, molybdenum and copper. The range of these alloys offers general corrosion resistance and also helps to stabilize the entire grade.
Table of Content
These Alloy 20 Round Bar are available in sizes between 4mm to 350mm and lengths up to 3000mm. We manufactured, Alloy 20 ASTM B473 Round Bars with a minimum tensile strength of 551Mpa and a minimum yield strength of 241Mpa.
Alloy 20 Round Bars‘ surface finished are available in black, bright polished, rough turned forms. We use high qualitative grades for these surface finishes.
Specifications come with Alloy 20 ASTM B473 Round Bar:
• Grades
• Sizes ranges
• Lengths
• Dimeter
• Tolerance
• Surface finishes
• Heat and cold condition
• Forms and types
The mechanical characteristics of Alloy 20 ASTM B473 Round Bars are given in the ranges to work well in both are excellent and in elevated temperature surroundings and working sectors.
The higher amount of nickel content in the bars helps improve the high-temperature behavior of the Alloy 20 Round Bar. In addition, nickel is an austenite stabilizing agent, which means the microstructure of this superalloy is an austenitic one, which is why the formability is considered to be good.
Applications of Alloy 20 UNS NO8020 Round Bar:
Alloy 20 UNS NO8020 Round Bars are useful for making building foundations, motorway bridges, tunnels. They are also identical to use for manufacturing barrier walls, bridges and marine facilities. They are also used in the manufacture of engineered filaments and plastics, petroleum and chemical handling hardware. These are the different sectors and applications where these round bars are used.
