A514 Gr B high strength steel plate product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
Composition characteristics of A514 Gr B high strength steel plate 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.
"Turkey has filed a lawsuit against EU steel import tariffs with the world trade organization, the trade ministry said Friday. In February 2019, the European Union said that the sharp increase of Turkish steel imports A514 Gr B high strength steel plate seriously threatened the steel producers in member countries. The European Union has set import quotas for 26 kinds of steel products and imposed a 25% tariff on future steel products for three years.
Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between A514 Gr B high strength steel plate, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of A514 Gr B high strength steel plate, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.
