1/2 x 3/8" BSP Black Steel Reducing Nipple 15mm x 10mm


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.
