In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the boiler steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.ASTM A283 CS steel carbon plate
ASTM A283 CS steel carbon plate,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.ASTM A283 CS steel carbon plate
We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
