Process specification for RINA grade E wash bulkhead steel in production

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 RINA grade E wash bulkhead steel 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 RINA grade E wash bulkhead steel customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll RINA grade E wash bulkhead steel, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

The RINA grade E wash bulkhead steel stainless steel 2250 mm wide coil mill has advantages such as adapting to difficult-to-deform steel grades. The Liuzhou Iron and Steel Hot Rolling Leveler project designed and supplied by MCC South is equipped with the latest straightening and leveling process (LTP technology) developed by MCC South. The RINA grade E wash bulkhead steel performance stability, cost and various consumption indicators have reached the international advanced level.

What is the difference between Q345B steel and Q345A steel? RINA grade E wash bulkhead steel, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other RINA grade E wash bulkhead steel steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market.
