Whether you’re sourcing components for a new build or replacing legacy parts, choosing the right iron casting partner can save time, cost, and future headaches.
At Fowler & Holden, we often receive RFQs missing the crucial questions buyers should be asking before production begins. This guide walks you through exactly what to consider – from material grades to casting compliance – so you get the right result, first time.
Common Use Cases for Iron Castings
1. Construction, Power, and Marine Sectors
Iron castings are everywhere — from drainage covers and pump bodies to turbine housings and marine brackets. The application defines the spec.
Before requesting a quote, confirm:
- Will this component face high pressure?
- Is corrosion resistance important?
- Will machining or finishing be required after casting?
Knowing the environment your casting will operate in helps us choose the right grade and process.
2. Legacy Parts and Replacement Castings
Fowler & Holden also produce castings from historical patterns or broken parts. Whether you’re replacing 1960s infrastructure or discontinued OEM components, we can reverse engineer and remanufacture it.
What Specs You Need to Provide
1. Grey vs Ductile Iron
Grey iron (Grade 250) is cost-effective and ideal for vibration damping. Ductile iron (also called SG Iron) offers higher strength and impact resistance. You don’t need to know the exact grade, but do let us know what the part needs to do.
Not sure which to choose? Just tell us the use case – we’ll advise on the best grade.
2. Material Standards: EN and ASTM
If your part is for regulated industries or exported abroad, let us know the standard you’re working to:
- EN 1561 for grey iron.
- EN 1563 for ductile iron.
- ASTM A48 / A536 for US origin castings.
We’re happy to supply full traceability and certifications.
Cost Factors to Consider
1. Batch Size, Complexity, and Tolerances
Casting cost is influenced by:
- Volume (one-off vs batch).
- Size and weight.
- Tolerances and machining needs.
- Pattern complexity (cores, undercuts, etc.).
Providing this info upfront gives you a more accurate quote – no surprises down the line.
2. Tooling Costs
For new parts, you’ll likely need new patterns. We offer competitive tooling with long-term reuse potential. If your part already exists, let us know – we may have compatible tooling in stock.

FAQs
What types of iron casting does Fowler & Holden offer?
We offer grey iron (Grade 250) and ductile iron (SG iron), with EN and ASTM compliance.
Is grey iron or ductile iron better for my application?
Grey iron is better for damping and static loads; ductile iron offers higher strength and ductility.
How much does iron casting cost in the UK?
It depends on size, batch volume, tooling needs, and finish. We offer competitive quotes tailored to your specs.
What standards do your castings comply with?
We comply with EN 1561/1563 and ASTM equivalents. Certification available on request.
Can I get a repeat order from a previous casting?
Yes – we store patterns for repeat work and can modify tooling as required.
