41cralmo7-10 steel is a high-quality alloy steel that has moderate levels of carbon, which improves its hardenability, and also contains chromium, molybdenum and vanadium, which contribute to its high strength and corrosion resistance. Compared with other types of steel, 41cralmo7-10 steel has a higher fatigue limit and stronger torsional stress resistance. It can be used to manufacture components that withstand high stresses and repeated loads, such as gears, shafts and bearings
41cralmo7-10 steel also has good machinability, weldability and formability, making it easy to process into a variety of shapes and sizes. This steel can be heat-treated to obtain different mechanical properties, such as high hardness and tensile strength, making it a versatile material.

Annealing:Heat slowly to 650-700℃. Cool in air.
Hardening:EN41B Nitriding Steel is supplied ready heat treated. If further heat treatment is required annealed EN41B Nitriding Steel should be heated slowly to 870-930℃ and after adequate soaking at this temperature quench in oil/polymer or water. Temper as soon as tools reach room temperature.
Tempering:Heat carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 580-700℃). Soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in the air.
