tensile performance of galvanized wire?

I.Action plan

1.Honest cooperation: We uphold the relationship of trust and responsible cooperation.

2,innovation and excellence: we pursue innovation that is valuable to the company and customers, and strive for excellence.

3,customer orientation: We insist on rapid response to meet customer needs.

Second, the code of conduct

1,we continue to learn and enterprising, resolutely put an end to inaction, love to fight and win.

2.We insist on personal interests to obey the overall interests, and individual honors obey the group honors.we are galvanized wire suppliers,you can know it.

3.We encourage courage to take responsibility, actively cooperate, help each other, and grow together.

4.We are close to the market, tap customer needs, respond quickly, and never delay.

5.We ensure product quality and high added value, and let customers use it in the first time.

6.We capture innovative breakthroughs in every detail of our work and continue to improve.

7.Our real job is to think about problems, ask questions, and solve problems.

8,we must do everything in place, do not make excuses, do not push, do not slap, resolutely popular.

9, we save a drop of water, electricity, one liter of oil, one grain.

The definition of tensile strength refers to the maximum tensile stress (that is, tensile failure load ÷ cross-sectional area) that the raw material can withstand before tensile fracture.

There are two indicators of yield strength, upper yielding and lower yielding. It is the process in which the stress does not increase and the deformation continues to occur during the stretching process. When the force value drops for the first time, the maximum stress is the yield strength; the yield strength is inevitably smaller than the tensile strength. value. Non-proportional extension strength: mainly for hard steel without yield point, the residual elongation of the gauge length is 0.2% of the length of the original gauge length is defined as the specified non-proportional extension strength; and the total extension strength is specified Stress at 0.5%. It is specified in the standard GB/T228.

Tensile strength of galvanized wire: 380-550 N/mm2, elongation: ≥15%.
