## Mechanical properties of 36NiCrMo16 (quenched and tempered)

Minimum values at room temperature in the +QT condition. d = diameter of rounds, t = thickness of flats.

| Property | 40 < d ≤ 100 mm / 20 < t ≤ 60 mm | 100 < d ≤ 160 mm / 60 < t ≤ 100 mm | 160 < d ≤ 250 mm / 100 < t ≤ 160 mm |
|---|---|---|---|
| Yield strength Re min (MPa) | 900 | 800 | 800 |
| Tensile strength Rm (MPa) | 1100-1300 | 1000-1200 | 1000-1200 |
| Elongation A min (%) | 10 | 11 | 11 |
| Reduction of area Z min (%) | 45 | 50 | 50 |
| Impact energy KV min (J) | 35 | 45 | 45 |

For sections outside these ranges, or for special strength classes, properties are agreed at order stage.

## Heat treatment of 36NiCrMo16 forgings

We could do annealing, normalizing, or hardening and tempering on 36NiCrMo16 forged parts as per the needs of the clients.

### Annealed or normalized

For clients who do the final heat treatment after rough machining. Annealing makes the steel softer for machining. Normalizing refines the grain after forging.

### Quenched and tempered (+QT)

Used to reach the strength and impact values in the table above. With about 4% nickel, 36NiCrMo16 has high hardenability, so big sections get more even hardness than grades like 42CrMo4. We set the tempering temperature by section size and the strength the client needs.

## 36NiCrMo16 forging production process

1. Steelmaking by electric arc furnace, ladle refining and vacuum degassing (EAF + LF + VD) for low hydrogen and clean steel.
2. Ingot or bloom cut and heated to forging temperature.
3. Open die forging or ring rolling to near-net shape with controlled forging ratio.
4. Heat treatment: annealing, normalizing or quenching and tempering.
5. Ultrasonic testing to EN 10228-3, SEP 1921 or ASTM A388; hardness and mechanical tests.
6. Machining to drawing, dimensional inspection and marking.
7. EN 10204 3.1 certificate, or 3.2 with third-party witness, and export packing.

## Applications of 36NiCrMo16 forged parts

- **Pumps and compressors:** rolled rings and shafts for chemical pumps, plunger pumps, gas compressors and industrial air compressors.
- **Power transmission:** forged gears, spindles, rings and bars for gearboxes, turbines and power generators.
- **Oil and gas:** discs, sleeves and bushings for onshore, offshore, subsea and deepwater production systems, wellheads and Christmas trees.
- **Pressure equipment:** forged shafts, pipes, tube sheets and flanges for pressure vessels, air receivers, shell and tube heat exchangers, columns, towers and tanks.
- **Valves:** valve stems, seat rings, blocks and bodies for ball, check, globe, gate and plug valves and strainers.
- **Heavy machinery:** crankshafts, eccentric shafts, rolls, wheels and manifolds for cement, sugar and concrete mills, shipbuilding, paper and pulp, and process plant.

## Testing and certification

Every 36NiCrMo16 forging is ultrasonically tested to EN 10228-3, SEP 1921 or ASTM A388, with acceptance class agreed per order. We issue an EN 10204 3.1 inspection certificate as standard, and an EN 10204 3.2 certificate when a third-party inspector witnesses the tests.

## 36NiCrMo16 FAQ

**What is 36NiCrMo16 steel?**
36NiCrMo16 (material number 1.6773) is a European nickel-chromium-molybdenum quenched and tempered alloy steel with about 0.36% C, 3.9% Ni, 1.8% Cr and 0.35% Mo. It has high strength, good toughness and high hardenability, and is used for heavy duty forged shafts, rings, discs and gears.

**What is the equivalent of 36NiCrMo16?**
The EN material number is 1.6773 and the closest French designation is 35NCD16. There is no exact AISI/SAE equivalent; AISI 4340 has similar alloying elements but lower nickel and lower hardenability.

**Which standard covers 36NiCrMo16?**
It was specified in EN 10083-1:1991 and is included in the current EN 10083-3. We can deliver to either edition or to your own specification.
