Material JIS SM490YA plates Chemistry

JIS SM490YA plates,,JIS SM490YA plates., European standard high strength EN10025-6 S690QL steel plates are mainly used for manufacturing construction machinery, mining machinery, all kinds of engineering machinery, such as the drilling rig, the electric shovel, the electric wheel dump, the mine motor, the excavator, and the loader for all kinds of engineering construction., etc.JIS SM490YA plates,We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with high-end steels and competitive price.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.Boilers with different parameters, different capacities, and different structures have different JIS SM490YA plates, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.JIS SM490YA plates
