Key Features:
1. Superior Wear Resistance and High-Temperature Hardness
• Excellent resistance to wear and thermal softening under high-temperature conditions.
• Strong resistance to thermal cracking, roll marks, and surface defects, with uniform wear ensuring consistent roll profile.
2. Stable Roll Shape and Plate Shape Control
• Advanced heat treatment ensures uniform material properties with fine grain structure.
• Roll body hardness uniformity ≤3HSD, and working layer hardness variation ≤3HSD.
3. High Mechanical Strength and Toughness
• High tensile strength (≥800MPa) with excellent impact toughness and thermal cracking resistance.
• Prevents oxidation layer peeling and working layer spalling during operation.
4. Outstanding Fatigue Resistance
• Exceptional wear resistance and fatigue performance reduce single-time grinding volume.
• Each regrinding provides an operational cycle exceeding 12 hours, with a total rolling capacity over three times that of high chromium cast iron rolls.
Customer Benefits
Using H3-B high-speed steel strip work rolls can help hot-rolled strip steel producers achieve:
• Reduced roll consumption per ton of steel.
• Improved surface finish of rolled plates.
• Reduced thermal and electrical energy consumption.
• Enhanced productivity and yield rates.
• Lower labor intensity for roll changing and grinding.
• Decreased spare roll inventory and capital tied up.
Application Scope
This material is suitable for work rolls in four-high roughing and finishing mills for hot-rolled strip steel (including endless rolling).
• Four-High Roughing Mill: Roll body hardness 82-86HSD.
• Four-High Finishing Mill: Roll body hardness 84-88HSD.
