Export S690QL carbon steel plate sheet to Zambia

Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the S690QL carbon steel plate sheet, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

We can cut the large steel plates S690QL carbon steel plate sheet by your requirements, but to the width and length your demand; we can make the surface of the cut steel plate to be bright by milling and grinding, also can make holes and make angle degrees, and can weld by your drawing. For the S690QL carbon steel plate sheet product thickness under 30mm, we mainly cut by laser cutting; for thickness over 30mm, mainly OXY-cut, flame cutting. The processing plates conclude cutting the larger plate into the small sizes customer demand, cut by drawing, cut to special sizes, weld the cut parts by drawing.

The microstructure of the quenched and tempered alloy steel, S690QL carbon steel plate sheet after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, S690QL carbon steel plate sheet sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
