API 5L X42 steel plate (L290) is pipeline steel. API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 0.9. The P265GH pressure vessel steel delivery status of API 5L X42 steel plate is hot rolling or controlled rolling. API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry.

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 pressure vessel steel 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 pressure vessel steel etc. steel is strictly controlled.

Hot rolled p265gh pressure vessel steel steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the p265gh pressure vessel steel processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

Our company will accept the product quality objection registration record, pass it to the p265gh pressure vessel steel production unit and relevant departments, and timely coordinate the supervision of product p265gh pressure vessel steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
