Our laboratory is capable of conducting a full suite of key inspection and testing items mandated by the standards of international and domestic classification societies (e.g., CCS, ABS, LR, DNV). We provide full-process support for raw material qualification, inOur laboratory is capable of conducting a full suite of key inspection and testing items mandated by the standards of international and domestic classification societies (e.g., CCS, ABS, LR, DNV). We provide full-process support for raw material qualification, in-process monitoring, and finished product verification:

1.Composition Traceability

Chemical Composition Analysis: Utilizing advanced equipment such as direct-reading spectrometers, we conduct high-precision quantitative chemical analysis of raw materials and finished products. This ensures the material composition fully meets the specification requirements (e.g., strict control of key elements including C, Mn, Si, S, and P).

2. Mechanical Performance Verification

• Tensile Testing: Conducted on high-tonnage universal testing machines (UTM) to precisely determine key material properties such as tensile strength, yield strength, and elongation. This verifies load-bearing capacity and forms the basis for confirming Minimum Breaking Load (MBL).
• Impact Testing: Performed using pendulum impact testing machines at specified low temperatures (e.g., -20°C, -40°C) to measure the material’s impact toughness (V-notch or U-notch) and evaluate its resistance to brittle fracture in harsh environments.
• Flexure Testing: Assesses material plasticity and process adaptability to ensure resistance to cracking during forming and service.
• Hardness Testing: Utilizes Brinell, Rockwell, or Vickers hardness testers to rapidly evaluate surface and core hardness uniformity, indirectly reflecting material strength and heat treatment effectiveness.

3. Insights into the Microstructure

Metallographic Analysis: Utilizing metallographic microscopes and image analysis systems, we examine the microstructure of materials (grain size, phase composition, inclusion rating). This enables precise assessment of heat treatment effectiveness (e.g., hardenability, tempering adequacy) and diagnosis of potential failure causes.

4. Non-Destructive Testing (NDT) – MT/UT/PT

• Magnetic Particle Testing (MT): Efficiently detects surface and near-surface defects in ferromagnetic materials, such as cracks, lap folds, and inclusions. Widely applied in post-weld inspection of chain links and accessories.
• Ultrasonic Testing (UT): Utilizes high-frequency sound waves to detect internal defects such as cracks, porosity, inclusions, and lack of fusion. With its deep penetration and precise localization, it is a critical method for ensuring internal quality.

5. Ultimate Strength Verification

Breaking Test: Performed on dedicated anchor chain tensile testing machines, this test includes proof load testing and destructive breaking testing on full-scale chain links or accessories. It serves as the ultimate step in verifying the actual breaking load, elongation, and failure mode of the anchor chain, ensuring it meets and exceeds the safety requirements of classification societies.
