The development of p295gh steel mechanical properties is of great significance

P295GH steel mechanical properties, 12MnNiVR steel plate is for large oil storage tank. Compared with SPV490Q in JIS G3115, the crack sensitivity coefficient PCM is lower, which is more conducive to steel plate welding; the sampling direction of impact test is changed from longitudinal to transverse, the impact temperature is changed from - 10℃ to - 15℃ or lower, and the impact energy is increased.

The effect of nitrogen (N) on the properties of p295gh steel mechanical properties and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in p295gh steel mechanical properties and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the p295gh steel mechanical properties quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After p295gh steel mechanical properties quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
