Precise analysis of mechanical properties with servo hydraulic
testing machine for steel strands in engineering
Test Objectives
Via tensile testing, the mechanical property indices of steel
strands are accurately derived, including tensile strength
(ultimate strength under peak load), yield strength (stress
corresponding to 0.2% plastic deformation), and elongation at break
(deformation capacity of the gauge length after fracture).
These quantitative data form the basis for analyzing the material's
mechanical behavior.
Test results are compared with design codes or relevant industry
standards to evaluate whether the steel strands meet safety and
reliability criteria for practical applications in bridges,
building structures, prestressed engineering, etc. This process
ensures the stability of engineering structures.
Working conditions
Ambient temperature should range from 10℃ to 35℃, with hourly
temperature fluctuations not exceeding 2℃.
Relative humidity must not exceed 80%.
Power supply voltage variation should not exceed 10% of the rated
voltage, with a frequency of 50Hz.
There should be no significant electromagnetic interference,
shocks, vibrations, or corrosive media in the surrounding area.
A minimum of 0.7 meters of space must be maintained around the
testing machine, and the working environment should be clean and
dust-free.
The levelness of the mainframe tabletop and frame shall not exceed
2.5‰.
Test Standards
GB/T 5224-2014, GB/T 228.1-2021, ASTM A416/A416M-21, ISO 6934-1
Price advantage
We enhance in-house R&D efforts and have established a
processing center to independently manufacture core components,
enabling us to cut intermediate costs while maintaining consistent
quality. Our high-quality products deliver far more savings than
cheaper, low-quality alternatives. By reducing machine failure
rates, we lower customers’ maintenance costs and boost operational
efficiency—this combination of competitive pricing and superior
quality brings real, tangible benefits to our clients.
Service advantages
Our comprehensive service range reflects professionalism through
customer satisfaction. Pre-sales, we offer thorough consulting
services, tailored to different industries to meet customers’
specific needs. Post-sales, we provide door-to-door installation
and training as required. During use, if any issues arise, you can
promptly reach our technical engineers via email, remote video,
phone, or other means. Machine parts are free of charge during the
warranty period, and we offer lifetime maintenance for the machines
.
