Duplex Steel Round Bar Heat Tolerance

Duplex steel round bars have excellent heat tolerance due to their unique composition and microstructure. They are designed to exhibit a combination of high strength and corrosion resistance even at elevated temperatures. However, the specific heat tolerance of duplex steel round bars can vary depending on the grade and the intended application.

Temperature Resistance

Duplex steel round bars have excellent temperature resistance.

They can withstand moderately high temperatures without significant loss of mechanical properties.

Oxidation Resistance

Duplex steel round bars exhibit good oxidation resistance, allowing them to resist the formation of scales and maintain their corrosion resistance even in high-temperature environments.

Thermal Stability

Duplex steel round bars have good thermal stability, enabling them to maintain their structural integrity and mechanical properties over a wide temperature range.

Phase Transformation

Duplex steels undergo a phase transformation at elevated temperatures, typically around 950°C (1740°F).

This transformation can affect the material's mechanical properties, so it's important to consider the specific alloy grade and its heat treatment requirements for optimal performance at high temperatures.

Manufacturing Processes of Round Bars

The manufacturing process of round bars depends on the material from which they are made. Here are some of the common manufacturing processes used to make round bars.

Hot Rolled Round Bars: Hot rolling is a process used to produce round bars from large billets or blooms. The metal is heated to a high temperature and then passed through a series of rollers to reduce its diameter. Hot rolled round bars have a rough, scaly surface and are not as precise as cold drawn or turned bars.

Cold Drawn Round Bars: Cold drawing is a process used to produce round bars from hot rolled bars or wire rods. The metal is drawn through a die to reduce its diameter and increase its length. Cold drawn round bars have a smooth surface and tight dimensional tolerances.

Turned Round Bars: Turning is a process used to produce round bars from hot rolled bars or billets. The metal is rotated on a lathe and a cutting tool removes material to produce the desired diameter and surface finish. Turned round bars have a smooth surface and precise dimensional tolerances.
