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, NV A40 passenger container ship steel, S275N plate is supplied up to 250mm.
High wear resistance: fully automatic CNC stacking equipment, independent of manual NV A40 passenger container ship steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the NV A40 passenger container ship steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite NV A40 passenger container ship steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.
Tempering the important NV A40 passenger container ship steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve NV A40 passenger container ship steel strength, plasticity and toughness.
We are specialized in offering hot rolled ASTM A516 steel plate, which are used in various engineering applications and can be availed in various grades like carbon steel NV A40 passenger container ship steel A516 Grade 60 steel plate , A516 Grade 65 steel plate, A516 Grade 70 boiler steel plate, ASTM A516 GRADE 60 plates Trippled Certified, ASTM A516 GRADE 60 Plates Dual Certified. Our boiler plates are available in the form of steel plate, steel sheet, steel sections. If you are interested in NV A40 passenger container ship steel boiler plate, welcome to contact us.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
