Features of Q235NHA sheet:Q235NH steel sheet has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving. It has a long service life when used in harsh environments. It has a protective rust layer to resist atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere.
X56 steel plate is a kind of steel mainly used for large-diameter pipelines. API X56 steel plate is used to manufacture buried pipelines for natural gas transmission. Due to the corrosion of soil, serious degradation will occur. The corrosion type of X56 steel plate that can be produced is usually general corrosion and pitting. we are API 5L X56 steel suppliers ,we also can supply API 5L X52,API 5L X60,API 5L X65,API 5L X70,API 5L X80,please contact us if you need.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the A514 grade E QT steel plate rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of A514 grade E QT steel plate steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
