What is Alloy 20 round bar?

Alloy 20 is an austenitic metal that has nickel, iron and chromium in its chemical composition. It was previously used for resisting acidic substances. The material can effectively resist the damaging effects caused by sulphuric acid. Alloy 20 round bar displays strong mechanical properties and can be machined & fabricated easily. It also displays min carbide precipitation post welding.The bars are ideal for acidic, corrosive and high temperature environments.

The ASME SB473 alloy 20 rounds can effectively resist chloride chemicals and thus, stress corrosion cracking. It also shows outstanding stability against various sensitization processes. They show high strength and heat treatable properties. Hence, the round bars are found in gas turbines, aircraft engines, thrust reversers, etc.

What are the carpenter 20 flat bar manufacturing and delivery times ?

The carpenter 20 flat bar manufacturing and delivery times can vary with the manufacturer capacity and their delivery capabilities. It also depends on the order size, customization requirements, material availability at the moment and complexity involved in the manufacturing process.

The time taken will be longer if the clients ask for additional tests and certifications required to ensure the material standard. You can contact Regent Steel & Engineering Co., if you need the fastest delivery of carpenter 20 hot rolled bars. We have a huge production capacity and we always adhere to project timelines.

What are the UNS N08020 hex bar handling and storage precautions?

To handle the ASTM B473 UNS N08020 hex bar properly you must use proper lifting equipment, Avoid dropping or impacting it in any way by using the right handling tools. Try to avoid any kind of abrasion as that causes surface defects. For proper storage, keep the hex bars in a dry environment and not in direct contact with the floor.

Make sure to avoid direct sunlight as that can discolor the bars. Keep them separate from other materials to avoid galvanic corrosion. Label and identify each product and regularly inspect them to avoid any defects.

What is the incoloy® alloy 20 square bar recommended temperature range?

The incoloy® alloy 20 square bars can be used in high temperature applications, as their melting point is around 1443 °C. The material can be hot formed within the temperature range of 1150 and 900 °C.
