Latest Patents

Terho Torvinen holds a patent for a "Method for manufacturing an austenitic steel object." This invention relates to a process that involves cold working an austenitic stainless steel strip to promote the formation of martensite within its microstructure. The method further processes the strip, which has a dual-phase microstructure, and shapes it into a desired object with at least one curved or arcuate area. During this shaping process, different areas of the strip are deformed to varying degrees. The final object undergoes reversion annealing to convert martensite back to its austenite form, achieving a fine grain microstructure, particularly in the curved areas.
