EN45 Round Bar

Robust quality of EN45 carbon steel Hex Bar Manufacturer in India.

Bars and rods are made up of different materials and can be divided into different specifications. One such bar made up of EN45 specifications is the EN45 Round Bar. It was developed to be used as connectors between pipes however they were then used as plug in pressure valves. However, EN45 Alloy Steel Rods are said to have a high demand in large scale industries. They are known for their durable leak proof property. They are usually supplied untreated or in cold finished condition. It is well known as low carbonmanganese free cutting steel.

EN45 Flat Bar

EN 45 Hex Bar

Wide size range suppliers of EN45 steel bar which is widely used for producing repetition products like nuts, bolts, hydraulic fittings, and studs. They are said to be difficult to weld and hence to attain high quality weld seam these bars are heated between the temperature range of 200 - 300 degrees C before welding. Post welding EN45 spring steel Square Bar is put through annealing. They are used in applications that require high temperature creep resistance,  fatigue life, resistance to oxidation, and phase stability. At times lead is also added to the EN45 flat bar. This enhances the machinability. They are widely used in components that require a good surface finish. The material used to manufacture these bars is also known as a high carbon alloy steel that is used to make swords.
