3/8" x 1/4" BSP Black Steel Reducing Bush Male Female


Black steel is made by adding carbon to iron during the smelting process. 

This creates iron-carbon alloys that are harder than pure iron but more brittle than other types of steel. 

Black steel has a matte finish that does not rust or corrode as easily as regular carbon steel due to its higher carbon content levels.
