WHAT YOU'RE SAYING "Just ordered a sheet of 304 stainless steel cut to tolerances of .005 of an inch. I measured 5 times before I ordered online last night. Just picked it up today before lunch and it fits perfectly! I could not be happier with the price or the quality of cut. It is 12 gauge and has no blueing or bending what so ever. Great Job Guys!!!!"

DID YOU KNOW...? ...that researchers have figured out how to 3D print one of the strongest stainless steels?
17-4 Precipitation Hardening (PH) Stainless Steel has high strength and durability and good corrosion resistance, making it essential for airliners, cargo ships, nuclear power plants and other critical technologies. 3D printing metal is more complicated than printing other materials like plastic, partly because of how quickly temperatures change during the process. This is particularly true in the case of 17-4 PH, for which the crystal structure has to be just right in order to achieve its desirable properties. Using a particle accelerator at Argonne National Lab, researchers smashed high-energy X-rays into steel samples during printing. They then "mapped out how the crystal structure changed over the course of a print, revealing how certain factors they had control over -- such as the composition of the powdered metal -- influenced the process throughout." Thanks to what they discovered, the researchers say that in the future "manufacturers should be able to print out 17-4 structures that are just as good as conventionally manufactured parts."
