What is the A573 Grade 70 for construction of storage tanks raw material

In production and operation, the company always attaches great importance to product A573 Grade 70 for construction of storage tanks quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market A573 Grade 70 for construction of storage tanks. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

We can supply profiled plate in a range of grades in thicknesses up to 400mm and dimensionally we can cut up to 24 meters in length and 5 meters wide with flame cutting, plasma cutting and laser cutting service. This capability is backed by an in-house CAD team, capacity that enables us to work to short lead times and an established delivery network that ensures you receive the steel A573 Grade 70 for construction of storage tanks products when you need it.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. A573 Grade 70 for construction of storage tanks, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

A573 Grade 70 for construction of storage tanks, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
