musashi99 - Solution annealed materials up to about 1-1/4" is diameter are first hot rolled in coil form, solution annealed and can be processed in one of 2 ways - (1) straighten/cut/ground or cold drawn/straighten/cut. Depending on the mill, changing from a cold drawn operation to a...
One thing that you may want to consider about citric acid. I have been told that citric acid is a good chrome and nickel getter. So reprocessing of the acids become very expensive and in some cases, reprocessors are dumping the acids due to these reasons. Has anyone else heard of this?

Besides the cost, you need to examine the level of defects you can tolerate. Cold finished steels, in particular stainless steels are governed by ASTM A-484, which outlines defect levels as well as bar tolerances. A cold finished bar can have defects up to 1% bar diameter. Turned, ground and...
Hello Everyone,
All the suggestions and comments were good and very valid. However, not many of these suggestions are in anyone's standard inventory. With an austenitic, you have to order a cold worked material which no one really stocks, especially these days. 17-7 is the same. Not really...
The material is Custom 450 and the reason he wants to change is because of the lack of availability. They want a material that is readily available. We thought about a duplex, but they need high strength and impact resistance. Duplex alloys just will not have the strength needed for the...
The application is a shaft in a blender (part of the shaft will be exposed). The food slury could be just about anything and temperature could be up maybe 120F. I saw the same web page, but just having a product brochure say it's used for food will not be enough to convince a government...
316 in condition B is a difficult alloy to find. Mills like Ugitech (the old Ugine-Savoie mill) will make the alloy but only in mill runs only. And this will be the case with most all mills.
My question about using 630 in the H1150 condition, do you have a requirement to use the material in...
I am working with a customer that wishes to change a shaft in food processing equipment to 17-4. But according to NSF guidelines, the material needs have chrome limits above 16%. Within these guidelines and the material properties he wishes to have (there is impact concerns), 440 A, B or C are...
I have an application where a titanium part for a dental instrument needs more mass and need to weld this part to a piece of stainless. We tried welding Ti-6-4 to 304L with absolutly no success via laser welding. Is there a procedure that can make this successful and/or is there a better...
