S355J0 steel and A573 Grade 65 steel equivalent material spec

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S355J0 steel and A573 Grade 65 steel equivalent, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts.
Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. S355J0 steel and A573 Grade 65 steel equivalent, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

We have a very S355J0 steel and A573 Grade 65 steel equivalent extensive commodity information network, with partners all over the world, and have become the full authority of many European and American traders in China. Under the guidance of the business philosophy of "creating the best service" and through the unremitting efforts of all employees, we have achieved remarkable results.

Although the research and development of steel for pipelines in China started late, the pace of development is fast. From the adoption of X60 steel on the Shaanxi-Beijing line in 1996, the successful application of API X70 pipeline steel in the West-East Gas Transmission Project in 2001, and the use of X80 pipeline steel on the Jining branch line in 2005. In just 10 years, China's pipeline steel has surpassed three steps.
