Welcome to BBN High Strength Steels Factory

S690QL material equivalent properties and application

The company adheres to the S690QL material equivalent external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of S690QL material equivalent quality and price and best service for all our customers.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled S690QL material equivalent plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy S690QL material equivalent steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.

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 material equivalent, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

Company management philosophy: integrity-based, service-oriented, excellence, affinity symbiosis. Based on quality, continuously create maximum value for customers. Always have a grateful heart, thank the society, thank family and friends for their support and help to the development of the company, thank customers for their trust, thank colleagues for their cooperation, and thank competitors for their supervision.
