I have a piece of annealed S1 for sale and it measures 2.254 x 6.180 x 10.884. I milled this piece square on all 6 sides so there are no saw cuts or mill scale. "S1 tool steel is a shock-resisting tool steel primarily used in applications requiring high toughness and impact resistance, such as cold work tools, forging dies, and shear blades. It's also suitable for hot work applications where medium hot hardness and high fatigue strength are needed." I'm located in NW Calgary, I will ship and I'm open to serious offers.
