6582 Steel Thyssenkrupp

High Tensile Nickel Chrome Steel

Steel 6582

Characteristics

6582 is a low alloy steel which comprises of 1.8% nickel, chromium and molybdenum, high hardenability and is capable of giving good properties in large sections.  It is relatively free from temper brittleness and retains useful machinability at relatively high hardness. Generally, Grade 6582 supplied in the condition of qunched and tempered  in the tensile range of 930 – 1080 Mpa (condition U) – (Rc 28 – 36). Characterised by high strength and toughness in relatively large sections. Pre hardened and tempered 6582 can be further surface hardened by flame or induction hardeningand by nitriding.

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. 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. Steel 6582 is used in most industry sectors for applications requiring higher tensile/yield strength than steel AISI 4140 can provide.
