Flame cutting characteristics of ultra-thick plates Oxygen and acetylene Because the size of ultra-thick plate parts is usually larger, the total amount of oxygen and acetylene consumed is much more. In order to complete the cutting of a single part at one time in the CNC cutting of ultra-thick plates, it is necessary to ensure a continuous and stable supply of sufficient oxygen and acetylene. BBN steel can supply P235GH steel welding machining parts for mine machinery, pressure vessels, LNG tanks and boilers.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel p235gh steel welding product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.

15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers p235gh steel welding (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

The effect of nitrogen (N) on the properties of p235gh steel welding 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 p235gh steel welding and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
