Machinery Steels : 6582
6582 is a low alloy steel which comprises of Nickle , Chromium and molybdinum.
All help enhance high strength and qunching ability Result from quenching is 54-59 HRC
and can applied in high temperature task due to its properties of temper embrittlement.
Grade 6582 sell in the condition of qunched and tempered. It suits and convenient for
further hardening uch as induction. Besides it can also do nitriding or nitro carburizeing
which will be better for resistance to wear and abrasive. Caution in application of 6582 I when
tempering up to 1400 Mpa , steel might be brittle due to hydrogen embrittlement.
So, it require hydrogen degassing for further pickling or plating. Tempering at hardness in the
range of 1500-1950 Mpa, will be at risk of crack due to tension and stress corrosion cracking.
• High toughness
• Resistance to fatigue
• Resistance to abrasive
• High forgability
• High Strength
• High ductility, bending is possible
• Machining ability is at mderate
• Not good for welding.
• Easy to quench and can do re quenching.
• Quenching up to 54-59 HRC
• Resistance to temper embrittlement
• Good for induction
• Can do Nitriding , surface hardness can reach to 650 HV
6582 is widely accepted to produce machinery part which require high strength or continuous
stress in an unstable condition. Especially power transmissin part like powertrain, crankshaft,
piston shaft, big size gear, worm gear, drive gear, bolt , strut , screw, Jig fixture
Also, aerospace structural part and landing gear.
