In simple terms, this standard covers stainless steel bars that achieve their high strength through a process called (also known as age hardening). These materials are prized for their unique combination of high strength, good corrosion resistance, and good toughness. astm a564 pdf
The "H" stands for Hardened, followed by the temperature (in Fahrenheit) used for the aging process. A lower aging temperature (e.g., H900) results in higher hardness, while a higher temperature (e.g., H1150) results in better ductility and toughness.
