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.we are galvanized wire suppliers,you can know it.
Tensile strength of galvanized wire: 380-550 N/mm2, elongation: ≥15%.
The galvanized iron wire has good toughness and elasticity, and the amount of zinc on the ** can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Products are widely used in construction, handicrafts, wire mesh, highway fences, product packaging and daily civil use.
Handicraft iron wire, using a special processing of a line, no broken ends, the amount of zinc on the uniform and bright, the general price is slightly more expensive.we are provide electro galvanized wire,we can guarantee quality.
