En1a Round Bar

The alloy for en1a round bar is a low carbon-manganese steel grade. This free cutting steel is also available with a modified en1a leaded chemical composition as grade EN1A Pb. The modified alloy is known to have enhanced machinability properties.

most trusted en1a leaded manufacturers, carbon steel en 1a bright bar suppliers

The good en1a mechanical properties of these components like the en1a leaded round bar are why they are used for hydraulic settings. In fact, the en1a leaded manufacturers recommend using these components, particularly for those applications which involve intricate drilling as well as machining operations. Generally, this grade of en1a rod is well suited for machining operations that use both automatic and CNC machines.

Also referred to as 230M07, the en1a bright bar could be case hardened in order to produce components. Case hardened en1a hexagon bar has enhanced wear resistance properties. These properties of the en1a steel flat bar are useful for the production of components which require a superior finished surface with a high rate of manufacture.

In comparison to regular mild steel grades, the carbon steel en 1a bright bar provides tighter sectional tolerances, in addition to the increased straightness, as well as a much cleaner surface. Usually, the en1a hexagon bar is supplied an untreated and cold drawn or centreless turned condition.  The main benefit of an en1a square bar is that the alloy steel could be brought closer to the finished machine size. Thus providing a reduction in the cost of machining. Another advantage of bright en1a steel bar is a marked increase in the tensile strength in comparison to a hot rolled bar of the produced under the same condition.
