Ship plate standard of 09CuPTiRE-B

EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, standard of 09CuPTiRE-B, S275N plate is supplied up to 250mm.

The company adheres to the standard of 09CuPTiRE-B external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of standard of 09CuPTiRE-B quality and price and best service for all our customers.

Quenching Improve the hardness of standard of 09CuPTiRE-B steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of standard of 09CuPTiRE-B steel and comprehensive mechanical properties.

The microstructure of the quenched and tempered alloy steel, standard of 09CuPTiRE-B after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

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.
