forged 1.2327/86CrMoV7 9CR2MOV alloy steel round bar

86CrMoV7 (corresponding to German standard 1.2327) is a high-carbon low-alloy cold working tool steel / cold rolling mill-specific steel. Its core characteristics include high hardenability, high hardness, wear resistance, fatigue resistance, and low crack sensitivity. It is mainly used for large-sized cold rolling mills and precision cold working molds.

I. Basic Information
Standard: DIN 17350, EN ISO 4957
Corresponding designation: 1.2327 (German material code), approximately 85Cr2MoV in China
Type: Cold working tool steel / Cold rolling mill-specific steel

II. Chemical Composition (mass fraction, %)
Element C Si Mn Cr Mo V P S
Range 0.83–0.90 0.15–0.35 0.30–0.45 1.60–1.90 0.15–0.30 0.05–0.15 ≤0.030 ≤0.030

III. Core Properties
Hardness: Can reach 62–65 HRC after quenching + low-temperature tempering; 100°C tempering ≈ 64 HRC, 200°C tempering ≈ 60 HRC
Hardenability: Excellent, uniform hardening for large sections (roll diameter ≤ 700mm)
Toughness: Moderate-high toughness, good impact resistance and fatigue resistance, low crack sensitivity
Wear resistance: High carbon + Cr/Mo/V composite strengthening, long wear life

IV. Heat Treatment Process
Annealing: Hold at 780–820°C, cool in furnace to ≤ 500°C and air cool; hardness ≤ 240 HB
Quenching: Oil quenching / salt bath cooling
Tempering: Hold at 180–220°C for 2–4 hours, air cool; common 200°C tempering, balancing hardness and toughness

V. Typical Applications
Cold rolling working rolls, supporting rolls, straightening rolls, finishing rolls
Cold working molds, punches, edge trimming molds, cold forging molds
Wear-resistant shafts, roll sleeves, wear-resistant parts of rolling mills

VI. Material Comparison (with common cold working steels)
Designation 86CrMoV7(1.2327) Cr12MoV(1.2601) 9Cr2Mo
Carbon content Medium-high carbon High carbon Medium carbon
Hardenability Excellence High Medium
Toughness Good General Good
Main application Large-sized cold rolling mills Heavy-duty cold molds Medium-sized and small rolling mills / molds
