75Cr1 Steel is a high-carbon, chromium alloy spring and tool steel known for high hardness, wear resistance, and good fatigue strength, commonly used for industrial springs, saw blades, and cutting tools due to its excellent hardenability and ability to achieve high hardness (around 58-61 HRC) after proper heat treatment

75Cr1 steel (DIN 1.2003) is a high-carbon, low-alloy steel, equivalent to AISI 1075 + Cr, British Bab 75, and often associated with CK75, used for springs, blades, and tools, offering better hardenability than plain C75 due to its small chromium addition (around 0.3-0.4%) for improved hardness and wear resistance.

75Cr1 steel is a high carbon steel with a carbon content between 0.74% and 0.80%. The addition of chromium facilitates the heat treatment process and allows higher hardness to be achieved than the standard C75 Carbon Steel. 75Cr1 carbon steel is a variation on En10132 C75.
