The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the P295GH chemical composition and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.

The effect of P and S content on the function of p295gh chemical composition, 15MnNiDR steel plate:Phosphorus (P): in general, phosphorus is a harmful element in steel. It will add the cold brittleness, make the welding function worse, reduce the plasticity and make the cold bending function worse.Sulfur (S): sulfur is also a harmful element in general. It makes the steel hot brittle, reduces the ductility and resistance of the steel, and forms cracks during casting and rolling.

The basic principle of p295gh chemical composition, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
