EN19 round bar also known as AMERICAN SAE 4140 round bar. 4140 Round Bar is a 1% chromium – molybdenum medium hardenability general purpose high tensile steel – generally supplied hardened and tempered in the tensile range of 850 – 1000 Mpa (condition T). All our 4140 Alloy Steel Bar supplied is Ultrasound and MPI inspected. EN19 bright bar is a high quality alloy steel with tensile strength. It is a high quality medium carbon. EN19 black bar is one steel grade in BS 970-1955 standard, which is specification for wrought steels for mechanical and allied engineering purpose. With a combination of good ductility and shock resistance, EN19 bar and en 19 flat bar is suitable for applications with very high loading such as engine gear boxes. EN19 square bar is a popular material in the automotive sector it is possible to machine the material extremely accurately. EN19 hollow bar material is also in demad by Oil & Gas industry. EN19 steel bar is a prime choice because of its high strength. The EN19 rod equivalent grades are AISI 4140 Rod, DIN 1.7225/42crmo4 Bar.

AISI 4140 steel round bar is an engineering alloy steel containing chromium and molybdenum. EN19 welding rod comes under the class of low alloy steel. EN19 round bars have high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. EN19 black bars can be heat treated in a number of ways to give it a combination of properties. Oil Quenched & Tempered Hardenss is 28-34 HRc. EN19 bright bar Annealing delivery hardenss is less than 250HB. En 19 round bar has high tenile strength of 850- 1000 Mpa. Steel Tubes India is a supplier of 4140 steel round bar to a number of companies in Mumbai, Pune (eg Chakan, Bhosari, Ranjangaon, etc), Aurangabad, Ahmednagar, Rajkot, Thane, Nagpur, etc.

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
