EN19 STEEL
EN19 STEEL GRADE
En19 steel is a high quality engineering alloy steel containing chromium and molybdenum. It falls in a class of low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. It can be heat treated in a number of ways to give it a combination of properties.
We can provide you En19 steel in the following forms
- Rounds (As rolled) – 23.5mm to 80mm
- Hexagons (As rolled) – 23.5mm to 52.5mm
- Round Cornered Square (RCS) – 55mm to 75mm
- Bright Bars (Rounds)- 21mm to 63.5mm
We are supplier of En19 steel to a number of companies in Mumbai, Pune (eg Chakan, Bhosari, Ranjangaon, etc), Aurangabad, Ahmednagar, Rajkot, Thane, Nagpur, etc. All our En19 supplied is Ultrasound and MPI inspected.

MATERIAL PROPERTIES OF EN19 STEEL FOR FABRICATION AND HEAT TREATMENT
EN19 steel has the following properties:
Machinability
This alloy steel has good machinability in the annealed condition.
Forming
EN19 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels.
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.
Heat Treatment
EN19 steel is heated at 845°C followed by quenching in oil. Before hardening, it can be normalised by heating at 913°C for a long period of time, followed by air cooling.
Forging
This grade of steel is forged at 926 to 1205°C.
Hot Working
EN19 steel can be hot worked at 816 to 1038°C.
Cold Working
EN19 alloy steel can be cold worked using conventional methods in the annealed condition.
Annealing
This steel is annealed at 872°C, followed by slow cooling in the furnace.
Tempering
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 a lower tempering temperature. For example, a 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).
Hardening
This alloy steel can be hardened by cold working or heating and quenching.
