300 Stainless Steel Castings
Alloys
Lamothermic pours a wide variety of ferrous and nonferrous alloys. Below are some of the more common alloys and specifications we can cast your parts with. If you don’t see your desired alloy on the list, we still may be able to pour it so please contact us, so we can talk about your needs.
Metallurgical Controls
We ensure all chemistries are in control by checking metal upon arrival and after each pour with a Thermo Scientific ARL 3460 Optical Emission Spectrometer.
