The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product grade P235GH steel standard more than 15 years.

The effect of nitrogen (N) on the properties of grade p235gh steel standard and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in grade p235gh steel standard and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. grade p235gh steel standard, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.
