Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for SPA-H weathering steel various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several SPA-H weathering steel after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
Difference between Q345R boiler vessel plate and ordinary Q345 plate, SPA-H weathering steel:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, SPA-H weathering steel.
"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.
Most common SPA-H weathering steel steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled SPA-H weathering steel steel plates.
