Steel grade 35NiCrMo6 KB is a high-strength alloy steel that is specifically designed to offer exceptional durability and reliability. It is widely used in various demanding applications where a combination of high mechanical properties and excellent resistance to wear and fatigue is required.

The mechanical properties of 35NiCrMo6 KB steel grade include a minimum tensile strength of 1000 MPa, a minimum yield strength of 800 MPa, and a minimum elongation of 14%. These properties make it suitable for applications that require high load-bearing capacity and resistance to deformation.

The chemical composition of 35NiCrMo6 KB steel grade is carefully formulated to achieve the desired mechanical properties. It mainly comprises carbon (C), manganese (Mn), chromium (Cr), nickel (Ni), molybdenum (Mo), and sometimes small amounts of other elements such as silicon (Si) and phosphorus (P).

The typical chemical composition of 35NiCrMo6 KB steel grade is as follows:

– Carbon (C): 0.32-0.39%
– Manganese (Mn): 0.50-0.80%
– Chromium (Cr): 0.90-1.20%
– Nickel (Ni): 1.50-2.00%
– Molybdenum (Mo): 0.25-0.35%
– Silicon (Si): 0.15-0.35% (optional)
– Phosphorus (P): 0.025% max (optional)

This specific chemical composition provides 35NiCrMo6 KB steel grade with excellent hardenability, toughness, and resistance to tempering and quenching. It also ensures good weldability and machinability, allowing for ease of processing and fabrication.

Overall, the combination of the mechanical properties and chemical composition of 35NiCrMo6 KB steel grade makes it an ideal choice for applications such as gears, shafts, axles, and other high-stress components in heavy machinery, automotive industry, and other demanding sectors.
