Note: *1. The nominal diameter and nominal tensile strength of the steel wire only indicate the steel wire grade.
*2. The nominal 0.1% conditional yield stress, nominal cross-sectional area and nominal mass are for reference only.
*3. The nominal tensile strength is calculated based on the nominal, area, and specified characteristic breaking load.
*4. The conditional yield load of 0.1% of the specified characteristic is approximately 83% of the specified characteristic fracture load. After negotiation between the supplier and the buyer, the characteristic load at 1% elongation can also be specified, which can be about 85% of the specified characteristic breaking load.
*5. Unless specified by the manufacturer, the modulus of elasticity is 205+10GPa.
*6. The maximum deviation of standard bricks is; tensile strength: 55MPa, or converted into load value; 0.1% yield stress: 66MPa, or converted into load value.
*7. In order to limit the deviation of diameter and area, the specified characteristic load is better than the specified stress.
