Steel is one of the fundamental materials used in modern construction, industry, and manufacturing, and precise quality inspection of steel is of utmost importance. Steel inspection technology ensures that the quality of steel meets the required standards, thereby improving product performance, preventing accidents and losses, and ensuring service life.

According to national standards, common items for steel inspection include chemical composition analysis, mechanical properties, hardness, corrosion resistance, and flaw detection. The specific indicators to be tested depend on the requirements of the experiment.

Scope of Inspection:

Steel plate inspection, steel strip inspection, stainless steel inspection, steel rebar inspection, stainless steel rod inspection, steel pipe inspection, welded steel pipe, stainless steel pipe, galvanized steel pipe, hot-dip galvanized steel pipe, hot-rolled steel pipe, cold-rolled steel pipe, plastic-coated composite steel pipe, seamless steel pipe for structural use, square pipe, rectangular pipe, alloy structural steel inspection, color-coated steel plate and steel strip, continuous hot-dip galvanized steel plate and steel strip, stainless steel cold-rolled steel plate and steel strip, carbon structural steel and low-alloy structural steel hot-rolled steel strip, stainless steel hot-rolled steel plate and steel strip, heat-resistant steel plate and steel strip, boiler and pressure vessel steel plate, stainless steel composite steel plate and steel strip, etc.

Inspection Items:

1. Mechanical properties: tensile, elongation, impact, bending, fatigue, compression, shear, fracture, peel, welding tests, etc.

2. Chemical composition analysis: C, Si, Mn, P, S, Cr, Ni, Cu, Mo, Ti, V, N, etc.

3. Metallographic analysis: microstructure, low magnification structure, grain size, non-metallic inclusions, welding structure, etc.

4. Hardness: Rockwell, Brinell, Vickers, Shore, etc.

5. Corrosion resistance: salt spray corrosion, stress corrosion, etc.

6. Coating performance: coating quality, adhesion, coating thickness, corrosion resistance, etc.

7. Ultrasonic testing: ultrasonic testing, non-destructive testing, ultrasonic weld seam testing, etc.

The National Center for Metal Product Quality Inspection and Testing has advanced imported equipment and highly educated test personnel. Ensuring the accuracy of data has always been our advantage. We can conduct various metal material inspections such as steel plates, steel strips, and steel pipes, and issue CMA and CNAS reports. If you need steel product inspections, please contact our engineer at the China Steel National Inspection Engineering.
