What Is The Difference Between A500 And A513 Steel
A500 steel offers increased strength and durability. It is most commonly used in structural applications. A513 steel, on the other hand, focuses on the manufacture of mechanical pipework and is used in areas where high levels of precision and mechanical properties are required.
What Plumbing Fittings Are Used To Connect Different Sizes Of Pipes
A500 steel is a cold formed welded and seamless carbon steel structural tube. It has good load carrying capacity and overall stability.
A513 steel is specially designed for resistance welded and seamless mechanical tubes. Good formability and workability.
