36CrNiMo4 Alloy Steel |1.6511| 4340|EN24 Steel
36CrNiMo4 Alloy Steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections.36CrNiMo4 Alloy Steel is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversely affecting mechanical properties.
DIN 36CrNiMo4 Alloy Steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. 36CrNiMo4 Alloy Steel steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 36CrNiMo4 alloy steel.
