Technical key points for the production of Q420B grade steel

According to the market forecast released by Eurofer on August 5, the output of all Q420B grade steel steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the Q420B grade steel steel consumption intensity in the construction industry significantly less than other industries.

10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. Q420B grade steel, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related Q420B grade steel products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export Q420B grade steel to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
