Welcome to BBN High Strength Steels Factory

Cost carbon steelS890Q equivalent plate

BBN is a S890Q equivalent world leader in exporting A106 / SA 106 pipe and stocks a full range of grades B/C with a size rage NPS 1/8" to NPS 48", with nominal (average) wall thickness as given in B36.10.

The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering S890Q equivalent steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.

S355J2 steel plate S890Q equivalent rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the S890Q equivalent single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

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 S890Q equivalent 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.
