DETAILED INFORMATION

What is EN19 steel grade?

EN19 steel is a high-quality engineering alloy steel that contains chromium and molybdenum. It is a low alloy steel. The material is highly fatigue-resistant, abrasion-resistant, impact-resistant, challenging, and torsionally strong. Heat treatment can be used to give it a variety of properties.

Although steel had been produced in bloomery furnaces for thousands of years, its use expanded greatly after more efficient production methods were developed for blister and crucible steel in the 17th century. In the mid-19th century, the Bessemer process ushered in a new era of mass-produced steel. Afterward, Siemens-Martin and Gilchrist-Thomas processes refined the steel’s quality. In addition, refinements in the process, such as basic oxygen steelmaking (BOS), led to lower production costs and higher metal quality. One of the most common materials in the world, steel is produced in more than 1.3 billion tons each year. Buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons contain it. Various standards organizations define different grades of modern steel.

A high-quality engineering alloy steel containing chromium and molybdenum is EN19 Steel. Low alloy steels fall into this category. The material has high fatigue strength, abrasion and impact resistance, toughness, and torsion strength. There are several ways to heat treat it to give it a combination of properties. The BS 970-1955 standard specifies wrought steels for mechanical and allied engineering applications, including EN19 steel. BS 970-1996 latest edition has a new version. The EN19 steel grade is similar to the 709M40 steel grade in the new version.

Properties of heat treatment:

The steel is heated to 845°C and then quenched in oil. To normalize it before hardening, it can be heated at 913°C for an extended period of time, followed by air cooling.

The tempering process:

Depending on the desired hardness level, EN19 alloy steel can be tempered at 205 to 649°C. The hardness can be increased by tempering the steel at a lower temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C(1000°F).

Forging Properties:

En19 steel is forged at 926 to 1205°C. 
Stress Relieving:
Annealed: 600-650°c Heat is needed.
Hardened: 500-550°c Heat is required.
Normalizing:
Heat 870°C – 900°C and cool in still air.
Annealing:
EN19 steel is annealed at 872°C and slowly cooled in the furnace.
Density:
The density of EN19 Alloy steel material: is 7.85 kg/cm3.
Machinability:
EN19 alloy steel has good machinability in the annealed condition.
Welding:
EN19 steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed.
