E470 20MnV6 seamless tubes supplier

Standard EN 10294 covers technical delivery conditions for alloy as well as non-alloy hollow sections such as bars. Bars manufactured under this specification are easily machinable and are used as parts in machines, which is why the letter E is added as a designation for E470 Hollow Bar. The minimum yield strength is always detailed along with the designation. For instance, for the  EN 10294 produced Hollow Bar E470, the minimum yield strength is about 470 N/mm2.

20MnV6 is a low carbon manganese alloy steel material. Being a low cost material, many businesses prefer its use, especially since the 1.0644 E470 20MnV6 High Tensile Low Alloy Steel Hollow Bar has a sturdy construction and its strength is almost similar to a regular solid bar. The size of the wall thickness of a hollow bar is much thicker than a pipe. Hence, its usefulness as a part of machines stems from its thick construction. Furthermore, the cost of an E470 ISO 2938 Hollow Bar in comparison to a regular solid bar is much cheaper, due to the absence of a solid core. This is also the main reason why the Carbon Hollow Bar to EN 10294-1:2005 E470 is light in weight, although it is heavier than a conventional pipe.
