Dec 08, 2019 · Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength
Study on Statistical Characteristic of Strength of Steel The typic steel plates of penstocks of hydropower stations in China are carbon steel of steel grade Q235 and high strength low-alloy steel of steel grade Q345. Therefore, we collected more than 20,000 groups of strengths testing data of the steel grades Q235, Q345, which are produced by representative steel mills in China during recent years.
Temperature Induced Creep in Low-Alloy Structural Q345 SteelJun 06, 2016 · This paper presents an experimental investigation into temperature-induced creep in low-alloy Q345 steel, which is commonly used in structural members. A set of creep tests is carried out at various stress levels in 300900°C temperature range.
Dec 14, 2019 · Q345 steel has good comprehensive performance and is a common brand of steel structure. Grade Q390 is also a recommended brand. Compared with carbon structural steel Q235, low-alloy high-strength structural steel can save steel 20% ~ 30%, and has good dynamic load and fatigue resistance. Low alloy structural steel is mainly used for rolling
