Title: The Innovations of Lewis L Kish
Introduction
Lewis L Kish is a notable inventor based in Sarver, PA (US). He has made significant contributions to the field of materials science, particularly in the development of methods for processing stainless steel. With a total of 4 patents to his name, Kish's work has had a lasting impact on the industry.
Latest Patents
One of Kish's latest patents is a "Method for batch annealing of austenitic stainless steels." This innovative method involves annealing coils of austenitic stainless steels using a batch annealing process. The preferred methods focus on selecting compositions of austenitic stainless steel alloys with a low weight percentage of carbon. This allows for annealing at temperatures below 1700°F, which is significantly lower than the typical annealing temperature for these materials. The process has shown successful results with T-201L and T-304L stainless steels, demonstrating effective annealing at temperatures ranging from 1550°F to 1700°F. Additionally, Kish has developed a "Process for producing dual phase ferritic stainless steel strip," which involves rapidly heating cold rolled stainless steel to annealing temperature in under 30 seconds, followed by a cooling step that transforms austenite to martensite.
