Welcome to BBN High Strength Steels Factory
According to the latest statistics of alacero, the consumption of finished steel S690QL steel material production products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil. The three countries accounted for 87% of the total reduction in S690QL steel material production steel consumption in Latin America. Alacero said the main reasons for the decline in steel consumption in the region are the global economic slowdown, the fall in commodity prices, trade disputes between the United States and its partners, the shrinking world trade S690QL steel material production and political uncertainty, as well as the negative impact on Latin American countries and their neighbors in terms of investment.
Our quality control department will do inspection for details of the steel materials S690QL steel material production before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. S690QL steel material production Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. S690QL steel material production, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of S690QL steel material production products.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S690QL steel material production EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
