What is EN19 Steel?
EN19 is a chromium-molybdenum alloy steel known for its excellent combination of strength, toughness, wear resistance and fatigue resistance. It is one of the most widely used engineering steels in forging, automotive, oil & gas, power transmission and heavy machinery industries.
EN19 is commonly supplied in the hardened and tempered condition and is preferred when components require higher strength than EN8 while maintaining good toughness and machinability.
For many engineering applications, EN19 provides an ideal balance between performance and cost, making it one of the most popular alloy steel grades worldwide.
EN19 Chemical Composition

| Carbon (C) | 0.36 – 0.44 |
| Silicon (Si) | 0.10 – 0.35 |
| Manganese (Mn) | 0.45 – 0.70 |
| Chromium (Cr) | 0.90 – 1.50 |
| Molybdenum (Mo) | 0.20 – 0.40 |
| Sulphur (S) | ≤ 0.05 |
| Phosphorus (P) | ≤ 0.05 |
EN19 Mechanical Properties
| Property | Typical Value |
|---|---|
| Tensile Strength | 850 – 1000 MPa |
| Yield Strength | 650 – 850 MPa |
| Hardness | 248 – 302 HB |
| Density | 7.85 g/cm³ |
| Elongation | 12 – 16% |
* Actual values depend on section size, heat treatment and supply condition.
Key Properties of EN19 Steel
High Strength
EN19 offers significantly higher tensile strength than carbon steels such as EN8 and EN9.
Excellent Toughness
Maintains good impact resistance even after heat treatment.
Good Wear Resistance
Suitable for components exposed to friction and repeated loading.
Superior Fatigue Strength
Performs well in rotating and dynamically loaded components.
Good Hardenability
Can achieve high mechanical properties throughout larger sections.
EN19 Heat Treatment
EN19 is highly responsive to heat treatment processes.
Annealing
Improves machinability and reduces internal stresses.
Hardening
Typically hardened by oil quenching.
Tempering
Provides the required balance of strength and toughness.
Induction Hardening
Often used to increase surface hardness and wear resistance for shafts and gears.
EN19 for Forging Applications
EN19 is extensively used by forging units because it offers:
- Excellent forgeability
- Consistent heat treatment response
- High strength after tempering
- Good machinability after forging
- Reliable performance in demanding applications
Forged EN19 components are widely used in automotive, construction equipment and industrial machinery.
Common Applications
- • Transmission shafts & Gear shafts
- • Gears & Pinions
- • Crankshafts
- • Spindles & Axles
- • Connecting rods
- • Studs and bolts
- • Hydraulic components
- • Oil & gas equipment
- • Forged engineering parts
EN19 Equivalent Grades
| Standard | Equivalent Grade |
|---|---|
| BS970 | 709M40 |
| DIN / EN | 42CrMo4 |
| AISI/SAE | 4140 |
| JIS | SCM440 |
* This is important because many buyers search for 42CrMo4 rather than EN19. EN19 and 42CrMo4 are widely accepted equivalent grades.
EN19 vs EN8
| Property | EN8 | EN19 |
|---|---|---|
| Strength | Medium | High |
| Toughness | Good | Excellent |
| Wear Resistance | Moderate | High |
| Hardenability | Moderate | Excellent |
| Typical Use | General Eng. | Heavy Eng. |
EN19 is preferred when components require significantly higher strength and fatigue resistance than EN8.
EN19 vs EN24
| Property | EN19 | EN24 |
|---|---|---|
| Strength | High | Very High |
| Toughness | Good | Excellent |
| Nickel Content | No | Yes |
| Cost | Lower | Higher |
| Typical Use | General Heavy Duty | Critical High-Stress |
EN19 is often selected when high performance is needed at a more economical cost than EN24.
