steel grade Q235NH produce the thickness range

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the steel grade Q235NH project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of steel grade Q235NH customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

Abrasion resistant steel plate has high wear resistance and good impact performance. steel grade Q235NH, Abrasion resistant steel plate can be cut, bent and welded. Abrasion resistant steel plate can be connected with other structures by welding, plug welding and bolt connection. It is time-saving and convenient in the maintenance process. Abrasion resistant steel plate is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. steel grade Q235NH, Abrasion resistant steel plate has a very high cost performance, and has been favored by more and more industries and users.

42CrMo alloy steel steel grade Q235NH: low temperature tempering welding performance thermal processing
The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This steel grade Q235NH method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.

We have a high-quality elite team, with a wealth of steel products resources and business experience. The company has established a perfect career development channel to provide all employees with broad job development opportunities, clear career planning, so that the potential can be fully explored, talent can be fully exploited, and a platform for employees to realize the value of life can be built, so as to realize the common growth and development with employees in the long-term development of the company.
