In modern industrial applications, metal parts are expected to perform under high loads, harsh environments, and continuous motion. Achieving both high strength and wear resistance is essential—but also technically challenging.

So, how can metal components meet these dual demands?

At DXTSEALS, we specialize in custom CNC machining of high-performance metal parts for applications where failure is not an option. Here’s how we engineer strength and longevity into every piece.

🧱 Step 1: It Starts with the Right Material

The foundation of a strong, wear-resistant component lies in material selection. Not all metals are created equal.

🏗 Common Metals Used for High Strength & Wear Resistance:

• Tool Steels (D2, H13, O1): Known for hardness and thermal resistance

• Alloy Steels (4140, 4340): Excellent toughness and fatigue strength

• Stainless Steel (17-4PH, 316): Corrosion-resistant with good mechanical properties

• Titanium Alloys: Lightweight with high strength-to-weight ratio

• Hardened Cast Irons & Nitriding Steels: Exceptional wear performance

Our engineers at DXTSEALS help select the most suitable alloy for your application, balancing strength, cost, and machinability.

🔥 Step 2: Precision Heat Treatment

After rough machining, metal parts can be heat treated to enhance specific mechanical properties.

Heat Treatments That Boost Performance:

• Hardening and Tempering: Increases hardness and tensile strength

• Case Hardening (Carburizing/Nitriding): Adds a hard surface layer while keeping the core tough

• Aging/Precipitation Hardening: Enhances both strength and corrosion resistance (common in stainless steels)

By controlling temperature, time, and cooling rate, we optimize the microstructure of the metal to meet exact performance needs.

🛠 Step 3: CNC Machining for Precision

High-performance metals require tight tolerance machining to function under extreme stress and motion.

At DXTSEALS, we use advanced CNC milling, turning, and EDM technologies to:

• Maintain dimensional accuracy to within ±0.005 mm

• Produce complex geometries for load distribution

• Ensure smooth finishes that reduce friction and wear

• Machine heat-treated materials without introducing stress

Our precision ensures your part not only fits perfectly—but also lasts longer.

✨ Step 4: Surface Treatments That Fight Wear

Even the strongest metals can fail without proper surface protection. We apply advanced coatings and finishes to boost wear resistance.

Common Surface Treatments Include:

• Nitriding / Carbonitriding: Hardens the surface while maintaining ductile core

• PVD / CVD Coatings (TiN, CrN): Ceramic coatings that reduce friction and wear

• Black Oxide or Phosphate Coating: Adds corrosion resistance and mild wear protection

• Shot Peening: Introduces compressive stress to prevent fatigue failure

These treatments enhance performance in abrasive, high-friction, or corrosive environments.

🧩 Step 5: Smart Design for Durability

Engineering high-strength, wear-resistant components also means designing for function:

• Filleted edges to reduce stress concentrations

• Reinforced load-bearing areas

• Symmetrical designs for even wear distribution

• Interchangeable inserts in high-wear zones

DXTSEALS works closely with clients to optimize part geometry for strength without overengineering or overcosting.
