Technical Specifications & Material Expertise

Uncompromising Quality: Material and Heat Treatment Specifications

Our authority in mining components stems from our commitment to material science and measurable quality control, ensuring our products perform reliably in the world's harshest environments.

Material Science & Forging

The base material for our flight bars utilizes proprietary alloy steel that achieves a minimum tensile strength and hardness suitable for heavy-duty applications. Our rigorous process includes a pre-stretching and shot-blasting phase, further increasing the component’s resistance to fatigue.

Hardness Range: Our standard flight bars are manufactured to achieve an excellent balance of high impact toughness and a hardness range of 270–380 HB (910–1290 MPa), allowing them to absorb extreme impact without fracturing while resisting abrasive wear.
Component Structure: The S-Type bar is typically supplied as a flight bar body and an optional wear plate (press bar), which can be straight or arched/bowed, depending on conveyor type.

S-Type Flight Bar Features & Benefits:

Precision-Forged S-Type Flight Bars: Built to Outperform

Our S-Type Flight Bars are not merely copies; they are optimized components built for the reality of high-tonnage mining. Every bar is subjected to a specialized manufacturing path that maximizes both impact resistance and wear characteristics.

Core Engineering & Design

Symmetrical, Direct-Fit Design: The S-Type's core geometry is engineered for universal fit, ensuring seamless installation into any conveyor pan designed for the S-Type footprint. This dual-direction capability is crucial for high-efficiency conveyor systems, enabling installation regardless of the transport direction.
Precision Forging: Manufactured using a world-class drop forging process. Forging shapes heated metal by hammering it into dies, producing components with superior strength and durability by ensuring the material’s internal grain structure flows along the component's contour
Calibrated Chain Seats: Critical attention is given to the final machining and calibration of the chain seat. This ensures an exceptionally smooth and stable ride for the chain links, significantly reducing friction and premature wear on the entire chain and conveyor trough.

Key Performance Advantages

Feature	Performance Benefit	Source
High Flexural Strength	Engineered with high-strength alloy steel to resist bending, twisting, and deformation under extreme, multi-directional stress loads.
Maximized Wear Resistance	Optimized heat treatment processes deliver a consistent Brinell hardness across the body, prolonging service life in highly abrasive coal and ore applications.
Operational Versatility	Symmetrical profile and dual-use capability simplifies inventory and installation, removing the risk of incorrect directional assembly.
Hardware Compatibility	Designed to ensure perfect fitment with common hardware, including	Hexagon bolts or Hammerhead bolts.

Specialized Features: Addressing Mining Challenges

Solving Your Toughest Operating Problems

We provide advanced material treatments to directly address the operational challenges that cause premature failure in conveyor systems.

Optional: End Induction Hardening (Ultimate Wear Resistance)

For applications in high-wear mining, which are subject to high volumes of rock (gangue), or use in tunneling and stone drifting, we offer an advanced End Induction Hardening option.

Process: This precisely controlled surface hardening method increases the hardness of the scraper end to up to 55 HRC (or $540 ? 600HV10$ ), significantly enhancing resistance to abrasion and maximizing the component's operational life.
Performance Insight: This specialized treatment slows the wear rate on the ends of the flight bar. It is explicitly confirmed by long-term testing that this hardened tip does not significantly increase wear on the side of the conveyor pan; pan wear is primarily determined by the abrasiveness of the conveyed material. This means you gain extended flight bar life without compromising the conveyor pan itself.
Hardness Grades: We provide different end-hardening grades to match the severity of your operational environment:
- CTH (Maximum Hardening): 51.8 - 55.1 HRC
- GTH (Enhanced Hardening): 45.7 - 49.9 HRC
- MTH (Light Hardening): 39.6 - 44.1 HRC

Solutions for Corrosive Environments

For corrosive underground environments, we offer specialized protective finishes to maximize the integrity and performance of your flight bars:

Tectyl (TEC) Coating: A standard protective coating suitable for good working conditions and shorter storage times. It acts as a lubricant, quickly fusing into the chain joints during initial use, minimizing severe primary wear.
Hot-Dip Galvanizing (TZN): Recommended for long-term storage and severely corrosive working environments. This process creates a permanent, dense, and highly adhesive zinc-iron alloy layer on the surface, offering superior wear and electrochemical protection. Hot-dip galvanizing is proven to significantly increase component service life in aggressive conditions.
