Latest Patents

One of McCunn's latest patents is a method for producing a weldable austenitic stainless steel in heavy section sizes. This innovative method allows for the creation of nickel-chromium-molybdenum austenitic stainless steel in welded article form, which is substantially free of second phase precipitation from annealing and welding temperatures. The process includes providing nitrogen additions and annealing at temperatures of less than 2100°F, preferably less than 2000°F. Another notable patent is for a ferritic stainless steel characterized by superior crevice and intergranular corrosion resistance. This steel consists essentially of, by weight, up to 0.08% carbon, up to 0.06% nitrogen, from 25.00 to 35.00% chromium, from 3.60 to 5.60% molybdenum, and other elements, with the balance being essentially iron.
