1. The mechanical properties in the table are applicable to steel rods with nominal diameter or thickness not greater than 80mm. The mechanical properties of steel rods with nominal diameter or thickness greater than 80mm shall meet the following requirements ① For steel rods with nominal size greater than 80~100mm, the elongation after breaking, the shrinkage of section and the energy absorbed by impact are allowed to be reduced by 1% (absolute value), 5% (absolute value) and 5%, respectively, compared with those specified in the table (2) For steel rods with nominal size greater than 100~150mm, the elongation after breaking, the shrinkage of section and the energy absorbed by impact are allowed to be reduced by 2% (absolute value), 10% (absolute value) and 10%, respectively, compared with those specified in the table (3) For steel rods with nominal size larger than 150~250mm, the elongation after breaking, the shrinkage of section and the energy absorbed by impact are allowed to be reduced by 3% (absolute value), 15% (absolute value) and 15%, respectively, compared with those specified in the table (4) It is allowed to change the sampling billet into a cross-section of 70mm~80mm before sampling, and the test results should meet the requirements in the table 2. The hardness in the table is the Brinell hardness value of the steel supply state of annealing or high temperature tempering 3. The impact absorbed energy in the table is the U-shaped notched impact test value
