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 sheet thickness range 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 sheet thickness range etc. steel is strictly controlled.

Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, p265gh sheet thickness range, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.

On November 9, 2020, the World Trade Organization (WTO) Safeguards Committee issued the Safeguards Investigation Circular submitted to it by the South African delegation on November 6, 2020. South Africa’s International Trade Management Committee makes decisions on the import of steel structure products including U, I, H, L and T Sections of Iron or Non-alloy Steel (U, I, H, L and T Sections of Iron or Non-alloy Steel). The safeguard measure is a negative preliminary ruling, and it is recommended to terminate the safeguard measure investigation in this case and not implement the safeguard measure.

Petrochemical equipment has been working under high temperature and high pressure for a long time, and the load situation is complicated. Frequent intermittent operations and start-ups and shutdowns often cause load and temperature fluctuations, resulting in equipment fatigue failure. Therefore, the research on fatigue performance of p265gh sheet thickness range, A387 gr22 cl2 steel, which is commonly used in petrochemical industry, under complex stress state has important theoretical value and engineering significance.
