BBN STEEL welding of SMA490BW corrosion-resistant plate exported to Iran

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the welding of SMA490BW corrosion-resistant plate project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of welding of SMA490BW corrosion-resistant plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel welding of SMA490BW corrosion-resistant plate is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the welding of SMA490BW corrosion-resistant plate steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the welding of SMA490BW corrosion-resistant plate steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed welding of SMA490BW corrosion-resistant plate materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
