Product Description

DIN 100Cr6 Steel
DIN 100Cr6 is a high carbon chromium bearing steel known for its excellent wear resistance, high hardness, and good toughness. Commonly referred to as 1.3505, it is widely used in the production of bearings, cutting tools, and mechanical components requiring high strength and wear resistance. It offers reliable performance in demanding operating conditions. Proper heat treatment and machining techniques are essential to unlock its full potential and ensure optimal performance in various applications.

Chemical Composition (%)
·Carbon (C)0.95-1.05
·Chromium (Cr)1.30-1.65
·Manganese (Mn)0.25-0.45
·Silicon (Si)    0.15-0.35
·Phosphorus (P)≤0.025
·Sulfur (S)≤0.025

Properties:
·High Hardness: DIN 100Cr6 steel achieves high hardness after heat treatment, making it suitable for bearing applications where wear resistance is crucial.
·Excellent Wear Resistance: Its high carbon and chromium content contribute to superior wear resistance, ensuring long service life even under high-load conditions.
·Good Toughness: Despite its high hardness, DIN 100Cr6 steel exhibits good toughness, allowing it to withstand impact and shock loads.
·Moderate Machinability: While machining DIN 100Cr6 steel can be challenging due to its hardness, it can be machined using carbide tools and appropriate cutting parameters.
·Moderate Weldability: It can be welded using conventional welding methods, but preheating and post-weld heat treatment may be required to minimize the risk of cracking.

Heat Treatment:
·Annealing: Heat to 800-850°C, then furnace-cool at a rate of no more than 10°C per hour. This relieves internal stresses and improves machinability.
·Hardening: Heat to 800-850°C, then oil quench to achieve maximum hardness.
·Tempering: Temper at temperatures ranging from 150-200°C to achieve the desired combination of hardness and toughness.

Applications:
·Bearings: DIN 100Cr6 steel is widely used in the manufacture of rolling bearings, including ball bearings, roller bearings, and tapered roller bearings.
·Cutting Tools: It is utilized in the production of cutting tools such as drills, taps, and milling cutters due to its high wear resistance and toughness.
·Mechanical Components: Common applications include gears, shafts, bushings, and piston pins in automotive, aerospace, and machinery industries.
