Steel Castings
Steel castings covers UK steel foundries producing carbon, low-alloy, stainless and duplex castings via sand, investment (lost wax) and shell processes. Buyers use this category for high-strength parts where fabrication is uneconomical or where a single homogenous casting outperforms a welded assembly - pump and valve bodies, impellers, mining and rail components, defence and offshore parts.

- You need high tensile strength with weldability and impact toughness
- You are replacing a complex weldment with a single casting to cut cost or lead time
- You need corrosion-resistant grades (CF8M, duplex, super duplex) for chemical, marine or offshore duty
- You need parts to specific standards (ASTM A216, A352, A487, A890, EN 10213)
- ISO 9001 and, where relevant, PED 2014/68/EU, NORSOK M-650, NACE MR0175 and ABS or Lloyd's approvals
- In-house heat treatment (normalise, quench and temper, solution anneal) with calibrated furnaces
- Full material traceability and spectro on every heat, plus mechanical test bars where required
- NDT scope: dye pen, MPI, UT and RT to ASME or EN standards, with a level 2 or 3 signatory
- Machining, coating and hydro-testing under one roof or through a controlled supply chain
Common questions about Steel Castings
Investment casting suits parts from around 25 pieces upwards. Sand casting is viable from a single prototype, though tooling amortises best at 20 to 200 pieces per order depending on part size.
Sand casting pattern equipment typically takes 4 to 8 weeks; investment tooling 6 to 12 weeks. Printed sand moulds skip tooling entirely and can deliver first-off castings in 3 to 5 weeks.
Yes, a handful of specialist UK steel foundries pour duplex (CD3MN, ASTM A890) and super duplex regularly for oil and gas, desalination and marine applications, with the ferrite balance and PREN testing that those grades require.
