Why This Route Exists
Steel castings and forgings carry the loads that decide whether a machine survives its duty cycle. Eurona sources these parts for load bearing, high strength and safety critical positions, using sand casting, shell moulding, open die forging, closed die forging and roll forging.
Every part is planned together with melting, heat treatment, NDT and quality documentation, so a buyer receives a certified part rather than a raw casting that still has to be qualified.
Published Specifications
These are the figures published for this process family. Values that depend on the specific part are confirmed during drawing review.

|---|---|
| Weight Range | Steel casting 50 kg - 20 T; forging 50 kg - 50 T |
| Process | Sand casting; shell moulding; open-die and closed-die forging; roll forging |
| Melting | High automation production lines with EAF + LF + VD / AOD melting routes |
| Tolerance | Zero draft sand casting to CT9 on automated heat treatment lines |
| Inspection | NDT with certified operators, single part certificates and quality document traceability |
Process And Quality Capability
Highly automated production lines with EAF + LF + VD / AOD melting equipment.
Certified NDT capability, supporting per-part certificates and traceable quality documents.
Automated heat treatment lines; zero draft sand casting reaches CT9.
What Usually Goes Wrong Without This Route
- Large steel parts fail acceptance because porosity and inclusions were never detected before shipment.
- Heat treatment is outsourced by the foundry and nobody owns the final mechanical properties.
- Certificates arrive weeks after the goods, which blocks incoming inspection and payment.

Background Reading
Casting or Forging How to Choose for a Load Bearing Part
The decision between a casting and a forging is usually made on shape complexity and load type rather than on price. This guide sets out the practical criteria.
Buying GuideWhat NDT and Quality Documents to Specify on a Casting Order
Most acceptance disputes come from an inspection scope that was never agreed. This guide covers what to specify and when to specify it.

Steel Castings & Forgings — Frequently Asked Questions
What weight range does steel castings & forgings cover?
Steel casting 50 kg - 20 T; forging 50 kg - 50 T
Which materials are available for steel castings & forgings?
42CrMo4, G20Mn5, G26CrMo4, G18NiMoCr3-6, G22CrNi2Mo5-6, AISI 4340, AISI 4140, AISI 4325 and similar grades
Can machining and surface treatment be included?
Yes. CNC machining, dimensional control, surface treatment and necessary pre-assembly are coordinated in the same supply chain, so parts can be delivered finished to the drawing.
What is needed to get a quotation?
Drawings, material, quantity, quality standard and target delivery date. Those five items allow a process route and a suitable production base to be proposed.
