Weldability of weldability of nm400 plate

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

The production process of weathering steel plate is complicated, which is also the key to guarantee its good performance. Through special production and processing technology, we can better apply weldability of NM400 plate, weathering steel plates to various fields. Like some home landscape design, we can see the different charms of weathering steel plates. Weathering steel plates are also used in the construction field. Weathering steel plates can be used to make stairs and walls, and have good practical effects.

weldability of NM400 plate, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of weldability of NM400 plate and No. 20 steel is 7.85kg/cm3

Because weldability of NM400 plate, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades. Whenever there is problem about our weldability of NM400 plate steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate weldability of NM400 plate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
