EN30B

En30B is a low carbon, high nickel medium chrome alloy steel shafting which is vastly superior to any 4140, 4150, or 4340 grade of alloy steel shafting. EN30B shafting is provided in a rough turned condition to remove mill scale. Ultra sonic testing is done following DGS method (flat bottom hole reference or FBH) and ASTM A388 recommendations. EN30B is normalized, quenched & tempered and stress relieved.

Standard Sizes:

3″ Dia. / 4″ Dia. / 5″ Dia. / 6″ Dia. / 7″ Dia. / 8″ Dia. / 9″ Dia. / 10″ Dia. / 11″ Dia.

*EN30B can be cut to length and turned to dia. size per customers specifications.

Typical Properties:

320-370 BHN Hardness

160,000 PSI Tensile – 135,000 PSI Yield (Typical)
