The advantages of , steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team It is a professional production team combining theory and practice With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel,API 5L X56 (L390) PSL1 steel material.API 5L X56 (L390) PSL1 steel material,Titanium microalloying is an element of strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.API 5L X56 (L390) PSL1 steel materialThe final heat treatment of quenched and tempered alloy steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.API 5L X56 (L390) PSL1 steel materialRelying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, steel sheets, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
