Steel supplier SA514 grade Q steel material hardness testing

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

European standard high strength EN10025-6 S690QL steel plates are designed to provide excellent welding and bending properties. Due to its high strength, it enables design of lighter, more durable and efficient products and structures with S690QL steel plates and SA514 grade Q steel material.

The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. SA514 grade Q steel material, 20CrMo steel pipe is generally used in quenching and tempering state.

The wear resistance of the surface of the wear-resistant composite plate not only has good hardness, but also can be added with nickel alloy to improve its corrosion resistance. Generally, there are few single working conditions in the industry, and there are more or less heterogeneous factors such as wear and corrosion, high temperature, impact, etc., the chromium-nickel alloy of the wear-resistant layer of the composite steel plate, SA514 grade Q steel material, is welded, so its wear resistance is good, and it also has good corrosion resistance.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.

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 SA514 grade Q steel material 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.
