hot rolled EN steel grade S460QL material low alloy steel

To the society: With the development of the company, BEBON has always adhered to the development mission of "developing heavy industry for the benefit of all mankind; improving the environment and achieving sustainable development”, operating with integrity and paying taxes in accordance with law.For our employees, the company fully respect employee value, pursuing mutual development of enterprise and employees.

As a pipeline of oil and natural gas, spiral pipe has its own characteristics: 1. The amount of use is large, because the specifications of EN steel grade S460QL material, spiral pipe used in a project are often diversified. During the forming process of the spiral pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not occure scratches. 2. The spiral pipe is used in a complex environment, and the quality must be guaranteed, otherwise it will delay the follow-up project progress.

EN steel grade S460QL material, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of EN steel grade S460QL material products.
