A514 Gr B quenched and tempered steel product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
Q345DR steel is a pressure vessel special plate with yield strength of 340MPa grade. It has good comprehensive mechanical properties and process performance. Phosphorus, sulfur content than ordinary 16Mn steel, in addition to tensile strength, elongation requirements than ordinary 16Mn steel has been improved, but also required to ensure impact toughness. A514 Gr B quenched and tempered steel was China's most widely used, the largest amount of pressure vessel special steel.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
