Welcome to BBN High Strength Steels Factory
S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The S960Q steel tubing, steel Grade S355NL making process shall according to EN10025-1.
S960Q steel tubing, Strip steel has obvious characteristics. First, it is thin and easy to bend, convenient for logistics and transportation, and saves logistics costs. Second, the surface quality of strip steel is good. Third, the strip steel is easy to process, and it can be processed only by straightening the bent part. Fourth, the strip steel has high precision and it is a good raw material for processing blades and saw blades. Strip steel is widely used in the manufacture of welded pipes, clamps, washers, spring blades, saw blades and other fields.
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 S960Q steel tubing 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 S960Q steel tubing 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.
The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products S960Q steel tubing price concessions, rich industry experience, complete varieties.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
