SA709 grade 50W carbon steel plate sheet equivalent jis material

The company is a large SA709 grade 50W carbon steel plate sheet steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the SA709 grade 50W carbon steel plate sheet enterprise, and make our own contribution to the development of the world economy.

SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, SA709 grade 50W carbon steel plate sheet, SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.

The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel SA709 grade 50W carbon steel plate sheet. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized SA709 grade 50W carbon steel plate sheet are higher than that of annealed SA709 grade 50W carbon steel plate sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of SA709 grade 50W carbon steel plate sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with SA709 grade 50W carbon steel plate sheet, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

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 SA709 grade 50W carbon steel plate sheet steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.
