This standard ASME SA516 is mainly used to improve the notch toughness important for welding steel plates for pressure vessels. The tensile strength of SA516Gr.60 (HIC) is 415MPa min. The main element content is C Mn Si, P and S control determines its performance. SA516Gr.60 (HIC) chemical composition: C: ≤0.30, Mn: 0.79-1.30, P: ≤0.035, S: ≤0.035, Si: 0.13-0.45. It is a carbon steel material for medium and low temperature pressure vessels.

In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.

16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². high strength structural steel grades, 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about high strength structural steel grades pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
