High strength BS700MC weldable structural steel good performance

In determining the type of BS700MC weldable structural steel, stainless steel products to be selected, the main considerations are the required aesthetic standards, the corrosivity of the local atmosphere and the cleaning system to be adopted. For example

In determining the type of BS700MC weldable structural steel, stainless steel products to be selected, the main considerations are the required aesthetic standards, the corrosivity of the local atmosphere and the cleaning system to be adopted. For example, 304 stainless steel is widely used in curtain wall, side wall, roof and other building applications, but in the corrosive industrial or marine atmosphere, it is better to use 316 stainless steel.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. BS700MC weldable structural steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the BS700MC weldable structural steel steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of BS700MC weldable structural steel extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate BS700MC weldable structural steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
