86CrMoV7 Forged Cold Work Roll for Stainless Steel Rolling Mill

Name: 86CrMoV7 Forged Cold Work Roll for Stainless Steel Rolling Mill
Brand: ETERNAL
Rating: 5.0 (77 reviews)

1.86CrMoV7 cold work roll is usually used in cold rolling mills to make stainless steel plate and strips,etc.

2.Besides 86CrMoV7 , other forged steels are also taken into cosideration,sunch as Cr2 series 9Cr2Mo, Cr3 series 9Cr3Mo/MC3/8Cr3MoV, Cr5 series 9Cr5Mo/MC5/8Cr5MoV,etc.

3.After forging, it will undergo spheroidizing annealing to remove inside stress and oil quenching heat treatment to reduce crack risks.
4.Double -frequency quenching for surface heatment to reach a high hardness value and depth layer.

5.Before shipment, we conduct 100% UT/MT quality testing according to testing standards such as EN 10228 series,ASTM A388M/A388、A966/A966M.

6.ETERNAL provides customized service.The diameter is upto 800mm and the length is upto 2500mm.

8Cr3MoV forging steel chemical specification :

8Cr3MoV	C	Si	Mn	Cr	Mo	V	P/S
8Cr3MoV	0.78-1.1%	0.4-1.1%	0.2-0.5%	2.8-3.2%	0.2-0.6%	0.05-0.15%	≤0.025%

8Cr3MoV mechanical property :

The core mechanical properties of 8Cr3MoV are characterized by high hardness, high wear resistance, and moderate toughness, with heat treatment process being the key. The quenching temperature is usually 1050-1100 ℃, and the tempering temperature is 180-220 ℃ (low-temperature tempering to maintain hardness) or 450-550 ℃ (medium temperature tempering to improve toughness).

Hardness: HRC 60-64, the hardness can reach HRC 62-65 after quenching, and maintains high hardness after tempering to meet wear resistance requirements.

Strength and toughness: The tensile strength is about 1800-2200MPa, and the impact toughness α k is 15-25 J/cm ², which combines high strength and certain impact resistance.

Wear resistance and red hardness: containing Cr, Mo, V elements to form carbides, excellent wear resistance; Red hardness is moderate, and it can still maintain good hardness in an environment of 250-300 ℃.

Processing performance: After annealing, the hardness is about HB 229-285, which can be used for cutting such as turning and milling. After quenching, it needs to be ground and precision machined.

Mainstream Cold Roll Steel
