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 S355J0W hot rolled steel structure 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 S355J0W hot rolled steel structure customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
15Mo3 steel plate/sheet is one mainly of Steel for boiler steels.DIN 17155 15Mo3 steel is mainly used for boilers and pressure vessels with elevated temperatures which is equivalent to EN10028 16Mo3 and UNI5869 15Mo3, 15D3 (NFA 36205 ) and ASTM A204Gr.B.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S355J0W hot rolled steel structure. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S355J0W hot rolled steel structure is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
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 S355J0W hot rolled steel structure products.
