How to Choose A Duplex Stainless Steel Casting Company?

If you have a project on duplex stainless steel casting, and would like to source it from China. Kindly remind that not all the stainless steel foundries in China can offer duplex stainless steel casting service. Most suppliers can only produce common cast stainless steel grades like 304/304L & 316/316L. For duplex stainless steels like 2205 & 2207, few foundries can have such casting capacility (refer to 2205 vs 316 stainless steel casting).

How to Choose A Duplex Stainless Steel Casting Company

It is worth to mention that duplex stainless steel castings are extremely corrosion resistant. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steel castings display properties characteristic of both austenitic and ferritic stainless steel castings.

When choosing a duplex stainless steel casting company, supplier qualification is the most important part in the purchasing process. Traditionally, a purchaser’s primary responsibility was to find qualified and responsive suppliers. In some cases, purchasers assumed that any supplier willing to contractually meet the purchase requirement was qualified. However, using low cost and unqualified suppliers can cause quality issues, and wasted time and money in the long run.

To help you through the process, here are some things to consider when choosing the right duplex stainless steel casting company.

Product Quality, Service, And Price
When selecting the right duplex stainless steel casting company, careful consideration should be given to quality, service, and price. Take an internal audit on what really is important to you, noting that most companies may be acceptable in all areas but can probably only truly excel in one. If the lowest price possible is most important, for example, the supplier will likely not be world class in quality and service. Which are your “Must haves”? Lowest price? Meet the spec? Quick response? Easy to do business with?

Machining Capabilities
Buyers increasingly select duplex stainless steel casting companies who have machining capabilities. This can avoid conflict if defects are discovered during machining. If a third party is machining, it may result in “finger-pointing” about who is at fault. Is it a casting issue or a machining issue? If the casting supplier discovers an issue during machining, the problem is resolved faster with no dispute over whose fault it is. The foundry “owns it” and there less time needed for processing, shipping, and handling or replacing. Problem or no, integrated machining simplifies the supply chain and reduces handling time and shipping cost before the product makes it to the customer.

Value Added Services
What do you need from that duplex stainless steel casting company? Are you looking for someone to just deliver a duplex stainless steel component to your doorstep or do you need more? For example, if you do not have in-house metallurgy expertise, confirm that the supplier can provide guidance in selecting the proper alloy based on your specific application. Do you have a need to raise the expertise of the overall metal in your company through training or information sharing? Does the duplex stainless steel casting company supply shipping service as well?

Do you want a China casting supplier who can review your design and material selection and provide recommendations to make your products last longer or save money? Some suppliers may do a great job producing a product to spec but have few other capabilities. Others will exceed the letter of the PO to help you save time and money. Will the duplex stainless steel casting part be 100% tested before delivery?

Tour Their Facility
What better way to determine if someone is the right duplex stainless steel casting supplier than to see their operations firsthand with a plant tour? Most manufacturers are more than happy to have you as a guest in an effort to gain your business. If, by the end of the tour, you have doubts about operations, capability or culture, they are probably not the right supplier for you.
