Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Point, 345 is the minimum value of yield strength for steel thickness less than 16mm. It is commonly used material among low alloy
To propose the models of mechanical properties of Q345 steel pipe at elevated temperatures which can be used for fire resistance design of the Q345 steel pipe structures. 2. Experimental study 2.1 Test method In this study the tests were divided into three groups:A, B and C. Group A was the thermal expansion test. Brief introduction of low alloy high strength steel 16Mn Sep 28, 2018 · Brief introduction of low alloy high strength steel 16Mn . Many steel material buyers purchase steel plate in China, especially high strength low alloy steel. 16Mn is kind of C-Mn steel, its carbon content is from 0.1% to 0.25% and with some alloy elements such as manganese (Mn), silicon (Si), vanadium (V), niobium (Nb), titanium (Ti) and other elements. 16 Mn is a kind of low alloy steel
