Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, A588 Gr A heavy plate angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding A588 Gr A heavy plate products, which we source out from the mills that are compliant with the universal guidelines for plate production.
Composition characteristics of A588 Gr A heavy 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.
Special boiler steel is derived from carbon structural steel, A588 Gr A heavy plate. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as A588 Gr A heavy plate.
A588 Gr A heavy plate product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic A588 Gr A heavy plate stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate. Contact us today to request a quotation or email us with your complete specification, we are happy to help you!
