What is chemical composition and mechanical properties of A573 Grade 70 for construction of storage tanks

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of A573 Grade 70 for construction of storage tanks boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with A573 Grade 70 for construction of storage tanks high-end steels and competitive price.

Composition characteristics of A573 Grade 70 for construction of storage tanks product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, 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 steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. A573 Grade 70 for construction of storage tanks, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of A573 Grade 70 for construction of storage tanks, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

The A573 Grade 70 for construction of storage tanks, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

How much is plate A573 Grade 70 for construction of storage tanks per ton?
FOB Shanghai: 635$/ton
q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.
