EN 10025-5 corten steel S235J0W structural specification scope freely

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of EN 10025-5 corten steel S235J0W, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. EN 10025-5 corten steel S235J0W, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This EN 10025-5 corten steel S235J0W method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate EN 10025-5 corten steel S235J0W EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
