S690QL1 material hot rolled boiler steel plate

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy S690QL1 material products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of S690QL1 material stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

The carbon S690QL1 material content of the pipeline steel is required to be low, and the strength of the pipeline steel is ensured by increasing the manganese content and adding trace elements such as niobium, titanium, vanadium and molybdenum. For pipeline steel, in addition to the required strength and plasticity index, the requirement for toughness index is an outstanding feature, including the impact energy of pipeline steel plate, impact transition temperature and toughness index of welding heat affected zone and welding metal. In addition, there are requirements for strain aging, weldability, stress corrosion and other indicators.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with S690QL1 material, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of S690QL1 material structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

2020 October stock S690QL1 material product: 8*1800*10950, 16*2150*10950, 70*2270*7350, 6*2200*10000, 20*3200*4400, 20*2280*5800, 20*2100*10800, 70*2270*7000, 12*2050*5100, 20*3200*4400, 12*2000*11850, 14*2940*9600, 20*2150*10000, 70*2260*7700, 6*1950*10000, 12*2000*11850, 6*2200*10000, 14*2510*10950, 16*2150*10000, 70*2260*7240, 20*3200*4400, 6*2200*10000,20*2100*7000, 12*2500*8000, 20*2100*10750, 35*2200*6800, 12*2000*11850, 20*2100*7000, 31.2*2950*9380.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
