Engineering Steel Bar

Bright Free Cutting Steel Bar En1A Leaded BS En 10277-3

Description:

EN1APb / 230M07Pb is a low carbon leaded free cutting steel, bright drawn or smooth turned with a consistently excellent level of machinability.The addition of lead plus the high sulphur and phosphorous levels form a lubricating effect resulting in extremely improved machinability with little affect on the mechanical properties.

Welding is not recommended due to high sulphur and lead content.

En1APb / 230M07Pb will electroplate but is not suitable for hot dip galvanising.

Used extensively in automatic screw machines for manufacturing parts requiring considerable machining and close tolerances.
