Boron alloy steel Angle

Boron alloy steel angle is a type of steel that contains a small amount of boron as an alloying element, which can improve the strength and hardenability of the steel. The numbers 2#-5#, usually refer to the different specifications or sizes of the boron alloy steel angle.

For example, 2# might refer to a boron alloy steel angle with a width of 20mm and a height of 20mm, while 5# might refer to a boron alloy steel angle with a width of 50mm and a height of 50mm. The specific specifications and sizes of the boron alloy steel angle may vary depending on the manufacturer and supplier.

This type of steel is commonly used in the construction industry for various structures, including buildings, bridges, and other infrastructure projects, due to its high strength and durability.
