Heavy-duty performance at half the material volume
At Super Quali Cast, we manufacture duplex steel investment castings for valves, automobiles, and pumps, delivering precision-engineered components for demanding applications. Our duplex steel castings offer higher strength than standard stainless steel castings while maintaining excellent corrosion resistance. Additionally, they retain their corrosion resistance post-welding and consistently meet demanding service conditions.
We are a trusted duplex steel casting manufacturer and investment casting company serving global industries. We export duplex steel investment castings to manufacturers and OEMs worldwide for valves, pumps, and automotive components. The businesses we work with are based in the US, the UK, Canada, Brazil, Saudi Arabia, the UAE, and Qatar. We also supply to industrial companies in Japan and Taiwan.
Duplex Steel Investment Castings Manufacturing Process
As a duplex steel investment casting company, we produce a wide range of precision-engineered components using this material. Casting them and manufacturing at scale involves the following steps:
- Mold Creation: Designing and producing wax molds to affix to a runner tree.
- Shell Building: Dipping the wax runner tree multiple times in a ceramic slurry.
- Dewaxing: Melting the wax mold to get the hollow ceramic shells with the negative space.
- Pouring: Gravity pouring molten alloys, such as duplex steel, into the empty shells.
- Cooling: Letting the alloy cool naturally, harden, and take shape.
- Knocking: Separating the duplex steel investment castings from the shells.
- Machining: Fabricating grooves, taking off excess material, and ensuring acceptable levels of surface finish.
- Testing: Investigating for signs of internal stress, microscopic cracks, and ensuring the product complies with industry standards.

FAQs
Can duplex steel investment castings help save on production costs?
Duplex steel offers higher strength than standard stainless steel, allowing reduced thickness and lower material usage in many applications. This translates to lower sectional thickness and reduced weight on account of less material requirement. Therefore, using duplex steel castings can help save on production costs.
Can duplex steel components be welded if required?
Yes, duplex steel components can be welded. In fact, welding doesn’t lead to loss in corrosion resistance. However, the filler material to be welded must be decided carefully to maintain the strength of the weld.
Does duplex steel have high fatigue resistance?
Yes, duplex steel has high fatigue resistance due to its material strength, making it a popular choice in manufacturing rotating equipment.
What makes a stainless steel duplex?
The alloy mix and production process are what make stainless steel duplex. Duplex steel has a mix of austenite and ferrite in nearly equal proportions. In this dual structure, either of the two components must be no less than 30% by volume. This is achieved through mill-annealing and water quenching.
