321 stainless steel has excellent high-temperature stress rupture performance and high-temperature creep resistance, stress mechanical properties, are better than 304 stainless steel. Austenitic stainless steel is equivalent to the Chinese grade 0Cr18Ni10Ti. 321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is better than 304. Due to the addition of titanium metal, A709 Gr 50 low alloy steel sheet, 321 stainless steel plate and sheet have better resistance to grain boundary corrosion and high temperature strength.
The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
Nickel element is mainly used to form and stabilize the austenite structure, so that the A709 Gr 50 low alloy steel sheet steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
A709 Gr 50 low alloy steel sheet, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.
Our quality and service commitment: A709 Gr 50 low alloy steel sheet product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
