Designed for low temperature resistant round Q345D North Run Shanghai Metal Materials Co., Ltd. Tel :021 -56,699,572 Mobile: 15601805059 Contact: Huang Yang Q345D low alloy plate a brand representation steel grades by the representative of the Chinese phonetic alphabet yield strength, yield strength values quality rating symbols composed of three parts, for example: Q345D. Where: Q-steel yield strength of the "bend" the word Pinyin first letter; 345 - yield strength values, unit MPa; D-quality grade of D-class (class is divided into A, B, C, D, E). When the demand side plate having a thickness direction required performance, then added after the prescribed grade represents the thickness direction (Z direction) performance level of symbols, such as: 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. Tensile strength :450-630. Elongation: ≥ 21. Impact test: -20 ℃: ≥ 34. 5 smelting method by the converter or electric furnace steel smelting, if necessary, add refining. 6 Delivery Status steel hot-rolled, controlled rolling, normalizing, normalizing and tempering, thermomechanical rolling (TMCP) state delivery. Edit this paragraph international comparison Q345D is our common low-alloy plate. And Germany S355J2, American ASTM A529MGr50 the same level, slightly different chemical composition, mechanical properties, the same. In normalizing delivery conditions, and Germany S355J2G3 is the same, and even S355J2G4 in performance is almost the same. Can be used interchangeably.
