Long-term cooperation. The following highlights the Company operated under the Q345E round material properties: the implementation of quality standards: GB / T1591-2008. Grade 1 steel grades representation by representatives of the Chinese phonetic alphabet yield strength, yield strength values, quality rating symbol composed of three parts, such as: Q345D. Where: Q- yield strength of steel "bend" the first letter of the word Pinyin; 345- yield strength values, units MPa; E- quality level for the E-Class (class is divided into A, B, C, D, E). When it is desired to have a thickness direction of the side plate required performance, then after the predetermined plus grade representative thickness direction (Z direction) performance level symbols, for example: Q345DZ15. 2 Executive Standard: GB / T1591 (GB / T3274). 3 Chemical Composition: C: ≤0.18; Si: ≤0.50; Mn: ≤1.70; P: ≤0.030; S: ≤0.025; Nb: ≤0.07; V: ≤0.15; Ti: ≤0.20; Cr: ≤0.30; Ni : ≤0.50; Cu: ≤0.30; N: ≤0.012; Mo: ≤0.10; Als: ≥0.015. 4 Mechanical Properties Yield: ≤16mm: ≥345; 16-40mm: ≥335; 40-63mm: ≥325; 63-80mm: ≥315; 80-100mm: ≥305; 100-150mm: ≥285; 150-200mm: ≥275; 200-250: ≥275; 250-400: ≥265.
