a516 grade 70 flat bar heavy plate boiler steel

With high-quality a516 grade 70 flat bar steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our a516 grade 70 flat bar steel market and improved the control of steel plate production quality.

Ship plate is a kind of steel plate used in shipbuilding, including thin plates and medium-thick plates. The China Classification Society rules divide steel plates into “ABDE” four quality levels, namely CCSA, CCSB, CCSD, and CCSE. There are many main materials for ship plates, such as a516 grade 70 flat bar, stainless steel, galvanized steel, shipbuilding steel plates, wooden ship plates, etc. Each material is used in different places. Generally, those large cargo ships at sea use stainless steel plates. Otherwise, if the ship plates rust, it will not only pollute the sea but also affect the ship itself.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate a516 grade 70 flat bar has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of a516 grade 70 flat bar stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the a516 grade 70 flat bar stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.

a516 grade 70 flat bar, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of a516 grade 70 flat bar and No. 20 steel is 7.85kg/cm3

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the a516 grade 70 flat bar principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
