Reliability test of steel wire and steel wire products

Steel wire and steel wire products are deep-processed products of wire rods in steel products. They have many varieties and specifications and are widely used. They occupy an important position in the national economy. In order to ensure the performance of steel wire and steel wire products, reliable performance testing is required. Tensile testing of steel wires and steel wire products can determine their reliable performance.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various steel wires and steel wire products, and provides professional tensile testing, bending testing, compression testing, hardness testing and other services for steel wires and steel wire products.

is suitable for cold-worked steel wires, annealed steel wires, quenched and tempered steel wires and coated steel wires with constant cross-section (circular or special-shaped).

Tensile test, torsion test, bending test, winding test, compression test, acid leaching test, hardness test, hardenability test, fatigue test, stress relaxation test, non-destructive test, chemical analysis, etc.
