... pressure dies are made of low-carbon steel, which can be case hardened to resist wear. Tool steel such as O1, A2, or D2, hardened to 55 to 60 HRC, or aluminum bronze is commonly used for sliding dies. In compression bending equipment, where the tube is clamped to a nonrotating form block, a wiper shoe...
