What is the difference between 20# steel and SA572 Gr 60 carbon steel plate sheet

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product SA572 Gr 60 carbon steel plate sheet annual capacity is 200 thousand tons.

According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw SA572 Gr 60 carbon steel plate sheet steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the SA572 Gr 60 carbon steel plate sheet market due to the impact of the closure of local steel mills in Italy.

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel SA572 Gr 60 carbon steel plate sheet is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.
