Haitian Heavy Industry | On-Site Inspection Passed – 100% Qualified High Manganese Steel Liners

Recently, our German client visited our factory for an on-site technical inspection of a batch of custom high manganese steel liners. The inspection covered comprehensive tests including dimensional measurements, hardness testing, surface defect checks, weld quality assessment, and installation fit verification, ensuring that the products meet the client’s stringent standards.

Our technical team provided a full overview of the manufacturing and quality control process, including:

• Chemical composition analysis and heat treatment of high manganese steel to guarantee wear resistance and impact toughness;

• Precision measurement using Coordinate Measuring Machines (CMM) to verify dimensional tolerances for perfect equipment fit;

• Multi-point hardness testing to meet design specifications;

• Non-destructive testing (NDT) to detect cracks, pores, and other defects;

• Pre-shipment trial assembly to ensure flawless installation.

  

The client highly praised our rigorous inspection procedures and confirmed that each liner fully complies with drawings and quality requirements, resulting in zero-defect, full batch acceptance.
