EN19 steel bright round bar also known as AMERICAN SAE 4140 round bar. EN 19 Bright 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 demand 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.
EN19 steel bright 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 Hardness is 28-34 HRc. EN19 bright bar Annealing delivery hardness is less than 250HB. En19 round bar has high tensile strength of 850- 1000 Mpa.

Steel is heated at 845°C followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C for a long period of time followed by air cooling.
Oil quench from a temperature of 85°C/88°C Celsius.
En19 alloy steel can be tempered at 205 to 649°C depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C(1000°F).
