The effect of nitrogen (N) on the properties of welding boiler plate steel GB 14Cr1MoR 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 welding boiler plate steel GB 14Cr1MoR and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
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 welding boiler plate steel GB 14Cr1MoR more than 15 years.
