A709 grade 100W bridge steel plate, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. A709 grade 100W bridge steel plate, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. A709 grade 100W bridge steel plate, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.
As the basic industry of the national economy, the steel industry is one of the most internationally competitive industries in my country. Li Xinchuang said: "During the new crown pneumonia epidemic, foreign steel companies have reduced production, suspended production or even shut down and withdrawn, while Chinese steel companies have basically maintained full capacity production, playing the role of 'ballast stone' in ensuring supply, protecting people's livelihood, and ensuring development."
It is not the thicker the steel plate is, the better. The larger steel plate thickness means higher price and purchase cost, and it is also not inconvenient for transportation. Besides, the thickness of A709 grade 100W bridge steel plate, steel plate has relation to the safety, so the thickness of steel plate is not determined at random, and the size data of steel plate should be strictly planned according to the requirements of drawings. Therefore, it is necessary to select the appropriate steel plate material and specification according to the use.
According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw A709 grade 100W bridge steel plate 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 A709 grade 100W bridge steel plate market due to the impact of the closure of local steel mills in Italy.
