What the price of hardening depends on
For small parts such as screws, nuts, bolts and springs, hardening is usually priced "per kilogram" or "per lot" rather than per piece, because the parts run in large batches through a continuous mesh-belt furnace.
The main factors that affect price:
- Material type — each steel grade (e.g. S45C, SCM440, SKD11) needs a different cycle and temperature.
- Required hardness (HRC) — the hardness spec and case depth affect the cycle.
- Quantity and total weight — the larger the lot, the lower the cost per kilogram.
- Follow-on finishing — if you need zinc or phosphate after hardening, it can be combined into one job, cutting extra transport.
- Shape and distortion risk — long, thin parts may need extra distortion control.
Why there is no "fixed price" on the website
Hardening is made-to-spec work, so the fairest price comes from seeing your drawing or a real sample. A generic published price usually means customers overpay, or get a spec that does not match the job.

How to order and get a quote
In short:
- Send a photo, drawing or sample with the material, quantity and target hardness.
- Get a quote within 24 business hours.
- Approve a sample lot before full production.
- Full production with in-house lab inspection and a test certificate on every lot.
What to prepare before asking for a price
Have these five things ready for an accurate, fast quote:
- Material type or grade (if unknown, send a sample to test).
- Target hardness (HRC) or the real application.
- Quantity per lot and frequency (one-off or repeat).
- Whether you need follow-on finishing (zinc / phosphate).
- Your timeframe (we tell you the realistic slot — we never promise beyond our actual capacity).
FAQ
Is hardening priced per piece or per kilogram?+
High-volume small parts are usually priced per kilogram or per lot, because they run in large batches through a continuous furnace, so the cost per piece drops as the quantity rises.
Is there a minimum order?+
It depends on the job. We focus on high-volume small parts — send the details and our team will assess it.
How do I get a quote as fast as possible?+
Send a photo, drawing or sample with the material, quantity and target hardness, and we reply with a quote within 24 business hours.
How many days does hardening take?+
It depends on volume and the production queue. We tell you the realistic slot when we quote, and we never promise beyond our real capacity so quality stays consistent.
