This 718 round bar just came out of its first forging cycle. Now it's being cut to size — ready for the next stage: custom profile forging.
No shortcuts. Just controlled processes, step by step.
At Baoya, we handle the entire chain — from melting to final forming. That's how we ensure every batch meets spec, inside and out.
Nickel alloys. Engineered right. From our mill to your production line.

Quenching — fire meets water, material transforms.

Red-hot round bars fresh from the furnace — now entering the quench tank.

Heat meets water instantly, steam rises. This is the essence of solution treatment — rapid cooling to lock the microstructure in its optimal state.

What you see is steam. What you don't see is performance taking shape.

Fresh out of the oven.

Fire meets water. Material takes form.

Out of the furnace and into the water — heat treatment cooling in progress.

When high heat meets rapid cooling, steam rises instantly. This is the critical step in solution treatment: locking dissolved alloying elements into the matrix structure, setting the foundation for the material's final strength and corrosion resistance.

What you see is steam. What you don't see is the microstructure transformation beneath the surface.

The same material grade can deliver vastly different performance.
The difference lies in raw material purity, in heat treatment time and temperature, in whether every step is done with care. These differences are invisible to the eye — but they show up in service life and reliability.

For every batch we produce, we record complete production data from melt to delivery — melting parameters, heat treatment curves, test results. Fully traceable.

An Inconel 718 API 6A tubing hanger — done.

Custom-shaped parts take longer than standard ones. From forging and turning to wire EDM, every step requires patience and attention to detail.

The wire EDM alone took 4 days. Not the fastest process — but to meet API 6A standards, some steps simply can't be rushed.

It may look like just a few numbers and dimensions on paper. In reality, it's the result of solid work in material and manufacturing.

The part is ready. Final sizing is left to the customer. We focus on what we do best — this step, we don't cut corners.

This ingot is being forged under the press, hit after hit. Every strike transforms its internal structure: cast dendrites are broken down, grains are refined, density increases.

Forging is not just about changing shape — it’s about making the material more uniform and more compact under pressure. With heat and force working together, strength and toughness are pushed to new levels.

From ingot to finished product — this step is essential.

718 ingots — fresh out of heat treatment. Cooling naturally.

A few Inconel 718 ingots just came out of the furnace. Now cooling.

The heat is slowly fading — the microstructure is stabilizing. This step can't be rushed.

From ingot to finished product, every step takes its own time.

No shortcuts. No skipping.

This valve stem is undergoing hardness inspection.
We use a Rockwell hardness tester. The principle is straightforward: a diamond indenter or carbide ball is pressed into the material surface under a specific load, and the hardness value is determined by measuring the residual indentation depth.
After the major load is applied, the indenter continues to pe*****te. Once the load is removed, the residual depth is measured. The shallower the indentation, the higher the hardness.
Advantages：
Fast operation — suitable for shop-floor batch testing
Small indentation — minimal impact on finished parts
Direct reading — no microscope required
Limitations：
Not ideal for very thin parts or shallow hardened layers
Requires relatively smooth surface finish
For valve stems, Rockwell is the preferred choice — fast, reliable, and non-damaging to finished surfaces.
Hardness passes. Valve stem ships.

Two large black-skin forged billets — fresh off the truck. Next up：cutting and sizing.

The rough exterior already holds a dense, sound structure after the first forging. After cutting, they'll be reheated and forged again, step by step, into the final shape.

From raw material to finished part — every step is real work.
