Supply Range of Steel Material 1.6587
Round Bar: diameter 20mm – 500mm (*stock material up to dia 300mm, check with us for stock list) Surface Finish: Black Surface, Milled Surface or Polished Surface as per given requirements. 1.6587 (18CrNiMo7-6) Equivalent Steel Grades As the casing hardening steel, 1.6587 grade is equivalent to: DIN 17210 17CrNiMo6 AFNOR 18NCD6 UNE 14NiCrMo13 Chemical Composition: What Makes Up 1.6587 Alloy Steel? 1.6587 material has the
Chemical composition below per EN 10084 standard
Carbon (C): 0.15 – 0.21% Manganese (Mn): 0.50 – 0.90% Silicon (Si): 0.40% Chromium (Cr): 1.50 – 1.80% Nickel (Ni): 1.40 – 1.70% Molybdenum (Mo): 0.25 – 0.35% Why DIN 6587 Steel Stands Out Versatility: It's applicable in numerous industries, from automotive to aerospace. Durability: Resistant to wear and tear, it's designed for the long haul. Machinability: Despite its strength, it's relatively easy to work with.
18CrNiMo7-6 (1.6587) / 17CrNiMo6 / 18CrNiMo7 Forged rough turned round bars
17CrNiMo6 is German DIN 17210- (86) standard steel number, European standard 18CrNiMO7-6, corresponding to GB 17Cr2Ni2Mo 17Cr2Ni2Mo is GB material. The specific standard number is: JB/T 6395-2010 large gear, gear ring forgings 17CrNiMo6 and 20CrMnTi difference: 17CrNiMo6 toughness is much better different carbon content, different alloy elements, different mechanical properties. The thermal process is also different. The front performance is superior, the latter gearbox gear, differential gear is widely used.

HEAT TREATMENT OF 18CrNiMo7-6 (1.6587) / 17CrNiMo6 / 18CrNiMo7 FORGED STEEL
-
Soft Annealing: Heat 17CrNiMo6 to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 229.
-
Normalizing: 850-880oC, air.
-
Hardening: Carburising: 880-980oC. Core Hardening: 830-870oC, water. Case Hardening: 780-820oC, water.
-
Tempering:Temperature: 150-200oC
-
Quality control:
1. Melting Process: EAF/BOF+LF+VD resulting in ingots
