What are the letters in the Q345 series?
Q345 series steel includes Q345A, Q345B, Q345C, Q345D, and Q345E, where Q represents the yield strength, the latter number 345 represents the yield point value (in MPa), and the letters A, B, C, D, and E respectively represent the low-temperature impact resistance of the steel, mainly due to the different impact temperatures.See all results for this questionWelding of Special Steels :: Total Materia ArticleSulfur is not added to any of the alloy steels. Leaded grades comparable to 12L14 and 11L18 are available. Unless the correct welding procedure is used, the weld deposits on free-machining steel will always be porous and will not provide properties normally expected of a steel of the analysis but without the sulfur or lead.Welding of Domexused, it can be absorbed at the cut surfaces of the steel, which may cause porosity in the weld metal. The solution lies in using oxygen as the plasma gas, or by grinding down the cut surfaces by at least an approximate 0.2 mm before welding. If thin sheet steel parts are to be welded together, ordinary shearing can be used as joint preparation.
