Tool Steel CPM 20CV Rectangular Bar 1-1/4" x 1/8" Retail Price

About CPM 20CV|A Crucible particle metallurgy (CPM) stainless tool steel with 1.9% carbon, 20% chromium, 4% vanadium, and 1% molybdenum. Truly stainless with extreme wear resistance from massive vanadium carbide content. PM (powder metallurgy) process ensures fine, uniform carbide distribution impossible to achieve through conventional melting. HRC 59-61. Used for high-performance knife blades, plastic injection molding screws and barrels where both corrosion resistance and abrasion resistance are needed. Compare to D2 (much cheaper, semi-stainless, less wear-resistant) and CPM S30V (less wear-resistant but tougher).

About Rectangular Bar|Solid rectangular cross-section stock. Functionally similar to flat bar but typically available in thicker, chunkier profiles. The naming varies by supplier — what one calls rectangular bar, another calls flat bar. Used for keys, gibs, wear strips, brackets, and any part where a rectangular starting profile saves setup time versus milling from plate.
