HAP5R (Toughness) HAP10 (M3:2) HAP40 (SKH40) HAP72 (High Hardness)🏭 Strategic Specialization in Extreme-Wear Semiconductor Tooling
As the primary HAP72 Supplier in Mumbai, Dipti Metal Industries addresses the most critical wear challenges in industrial manufacturing. HAP72 is produced using advanced gas atomization and hot isostatic pressing, resulting in a steel with a massive volume of ultra-fine carbides. While molten steels become extremely brittle at high hardness, HAP72's PM structure allows it to maintain sufficient structural integrity at 70 HRC to resist the intense abrasive wear and pressure found in IC mold encapsulation and high-speed punching of abrasive materials.
The HAP72 Technical Edge
- Highest hardness of the PM HSS series (up to 71 HRC)
- Exceptional compressive strength and pressure resistance
- Superior dimensional stability during complex hardening
- Isotropic property distribution due to powder metallurgy
Solving Extreme Production Challenges
- IC Molds: Resists abrasive molding compounds in electronics.
- Long-Life Dies: Outperforms HAP40 by 3x-10x in high-wear zones.
- IC Lead Frame Punches: For ultra-precision punching.
- Cold Plastic Deformation: For extreme material displacement.
📘 Technical Specifications: The HAP72 Engineering Profile
HAP72 is the definitive choice for applications where "standard" high-speed steels fail too quickly due to abrasive wear. It is the hardest metal option before moving to cemented carbides, offering easier machinability and better toughness than tungsten carbide.
