Grade E355+N are alloy bars that contain a substantial microalloying addition of manganese, nickel and chromium along with trace quantities of elements like phosphorus, sulfur. These elements aid in superior machinability of the EN 10294-1 Hollow Bars. Grade E355 +N is indicative of several aspects of this steel alloy. For instance, the letter E means that this particular steel grade is well suited for machining.
While the number 355 mentions its minimum yield strength. And lastly, the letter +N in EN 10294-1 Grade E355+N means that the hollow bar is to be supplied in a normalized condition. In comparison to the traditional carbon steel bars, alloy steel hollow bars have superior strength, more toughness and much better corrosion resistance properties. Generally, these components are recommended for use in operations that require high strength and durability. As opposed to pipes or tubes, the wall thickness for EN 10294-1 Alloy Steel Hollow Bar is much thicker. Furthermore, the properties of the metal are also responsible for delaying the onset of decay or corrosion. Thus, adding value to the application. If a higher corrosion resistance property is desired, buyers have the option of getting these hollow bars coated or their surface treated by various common techniques sich as galvanization or zinc coating.
