Manufacture the p265gh equivalent astm material with surface heat treatment

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 P265GH equivalent astm material 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.

SA299 carbon-manganese-silicon steel plates for pressure vessels are produced in two grades: SA299 GrA and SA299 GrB. The maximum thickness of the p265gh equivalent astm material, SA299 steel plate is only limited by the ability of the chemical composition to meet the specified mechanical performance requirements. But at present, the maximum SA299 plate thickness is usually limited to 8in. (200mm) or less.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of p265gh equivalent astm material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in p265gh equivalent astm material etc. steel is strictly controlled.
