S890QL EN 10025-6 high strength steel normalized and impact tested plate

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. S890QL EN 10025-6 high strength steel, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. S890QL EN 10025-6 high strength steel, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This S890QL EN 10025-6 high strength steel alloy steel S890QL EN 10025-6 high strength steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

During the construction of hot-dip S890QL EN 10025-6 high strength steel galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the S890QL EN 10025-6 high strength steel construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our S890QL EN 10025-6 high strength steel products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

Our company will accept the product quality objection registration record, pass it to the S890QL EN 10025-6 high strength steel production unit and relevant departments, and timely coordinate the supervision of product S890QL EN 10025-6 high strength steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
