DETAILED INFORMATION

Triroundbars.com is one of the leading EN45A Round Bar Manufacturers, Exporters, and Suppliers in India. This EN45A Round Bar is made of pure medium carbon steel and has a ductile strength comparable to mild steel. EN45A Carbon Steel Bar can be used for a variety of manufacturing applications that require high strength, such as the production of tubes, studs, bolts, connecting rods, screws, and rollers. 

EN45 Spring Steel is a silico-manganese steel that is widely used to make round bars, flat bars, and rods. Despite being produced in both strip and bar form in the past, the development of more sophisticated strip steels has led to a decrease in availability in strip form. 

The most common form of EN45 is a rolled flat bar, which is formed with or without heating and quenched and tempered when the desired shape has been achieved. The EN45 Round Bar and Flat Bar is capable of taking up a good hardness and offers good tempering stability.

We are ISO Certified Suppliers and Exporters of En 45 Bright Bar, En 45 Round Bar, En 45 Flat Bar, En 45 Hexagon Bar, En 45 Square Bar, En 45 Rectangular Bar, En 45 Rod, En 45 Hex Bar, En 45 Mild Steel Bar, Spring Steel En 45 Bright Bar, En 45 Black Bar, En 45 Forged Bar, En 45 Ground Bar, En 45 Hollow Bar in varied gulf countries, namely Bahrain, Kuwait, Iraq, Oman, Qatar, Saudi Arabia and the

Leaf springs and knives are made from EN45, a silico-manganese spring steel. This silicon manganese spring steel (approx. 0.55% carbon) is suitable for oil hardening and tempering. 

Despite being available as both strip and bar in the past, it is no longer generally available as strip because of the development of more sophisticated strip steels.

EN45 is typically supplied as a black rolled flat bar, which is formed with or without heating, and quenched and tempered once the desired shape has been achieved.

The EN45 standard is suitable for the manufacture of springs and blades. It is widely used in the manufacture of automotive leaf springs and historical blades. Equivalent grades include 250A53, 250A57, and 55SiMn7.

BSS supplies EN45 flat and round bars with a typical as-rolled hardness of 220/240vpn.
