What Does OSTE Stand For?

OSTE stands for One Step Temper Embrittlement

OSTE, or One Step Temper Embrittlement, refers to a phenomenon in metallurgy where a material, typically high-strength steel, experiences a loss of toughness during a single heat treatment step, particularly in the tempering process. This embrittlement can adversely affect the material's mechanical properties and performance in applications, making it essential for engineers and materials scientists to understand and mitigate its effects in order to ensure the reliability and safety of steel components.
