EN19 round bars Characteristics:

• This material distorts when machining shafts or long spindles, especially once hardened and tempered

• In practice, the work pieces should be rough machined to plus tolerance and left in the open on the floor for 36 hours after which the material would have “aged” and stress relieved itself and thereby minimising distortion on the finishing of the product

• Machinability is good but allow 6% on outside diameter for removal of surface defects

• This material can be welded but welding should only be attempted by using the appropriate methods and materials as advised by welding expertise

• Ideal for 60 ton tensile applications up to 100mm max

• Sizes above limited ruling section will be heat treated to hardness only, with no guarantee on mechanical properties

EN19 round bar Applications:

• Utilised when higher than carbon steel mechanical properties are required

• Commonly used for axles, drive shafts, crankshaft connecting rods, high tensile bolts, studs, propeller shaft joints, rifle barrels, and induction hardened pins

• Bolt specification: 9.8 (in condition “T”)

• Bolt specification: 10.9 (in condition “U”)

• Gears

• Pinions

• Shafts

• Spindles

• Oil & Gas Industries
