Hot Work Die Steel​ Blades

Our Premium Hot Work Die Steel Blades are manufactured from advanced chromium-molybdenum-vanadium alloy steels specifically formulated to withstand extreme thermal cycling and abrasive conditions:

• H11/H13 Hot Work Steel: Contains 4.75-5.50% chromium, 1.10-1.60% molybdenum, and 0.30-0.60% vanadium for exceptional thermal fatigue resistance and toughness at elevated temperatures
• Enhanced Chromium Content: 5% chromium composition provides superior resistance to thermal softening and oxidation up to 600°C 
• Precision Heat Treatment: Undergoes specialized annealing, quenching (1000-1050°C), and multiple tempering cycles (520-700°C) to achieve optimal microstructure
• ESR/VAR Processing: Electro-slag remelted and vacuum-arc refined steels ensure high purity, homogeneity, and superior directional toughness 

These advanced materials maintain hardness of HRC 48-56 even under continuous thermal cycling between room temperature and 600°C, offering unparalleled performance in demanding hot work applications.

Selecting the optimal Hot Work Die Steel Blade requires careful consideration of your specific thermal and mechanical operating conditions:

1. Operating Temperature Range: H11/H13 grades excel at continuous operation up to 600°C, while specialized grades can handle brief exposures to 800°C
2. Thermal Cycling Frequency: For rapid heating/cooling cycles, choose blades with enhanced thermal fatigue resistance (minimum 30-50 J impact toughness)
3. Abrasion Resistance Needs: Higher vanadium content (0.8-1.2%) provides superior wear resistance against abrasive materials at high temperatures 
4. Cooling Method Requirements: Our blades can withstand limited water cooling without damage, crucial for hot forging and extrusion applications 
5. Mechanical Impact Expectations: Applications involving impact loads require blades with optimized toughness-strength balance 

Our technical specialists provide application analysis to recommend the ideal steel grade, hardness profile, and coating solution for your specific thermal and mechanical requirements .

Proper maintenance is critical for maximizing performance and longevity of hot work blades operating under extreme conditions:

• Thermal Cycling Management: Implement controlled heating and cooling rates to minimize thermal stress accumulation and heat checking 
• Regular Hardness Verification: Periodically check blade hardness (HRC 48-56 range) to detect early-stage thermal softening 
• Surface Inspection: Monitor for heat checking cracks using dye penetrant methods during scheduled maintenance intervals
• Proper Storage Conditions: Store in dry, temperature-controlled environments with protective coatings to prevent corrosion
• Professional Reconditioning: Utilize stress relieving treatments (600-650°C for 1-2 hours) to extend service life between regrinds 

Following these maintenance protocols typically extends blade life by 1.5-3 times compared to conventional hot work steel blades, significantly reducing operational costs.
