How to solve the uneven heating problem of mechanical properties of nm550

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

The steel plates for SA302GrC boilers must withstand different pressures and strengths due to the manufactured containers. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C and 450°C. According to the working conditions and processing requirements of the vessel, the steel plate must have good cold bending and welding performance, good plasticity and toughness, and high temperature short-term strength or long-term strength performance.

SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the mechanical properties of NM550, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.

Weathering steel plate mechanical properties of NM550 for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate mechanical properties of NM550 has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to mechanical properties of NM550 customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
