EN30B Alloy Steel Round Bar (835M30)

EN30B Round Bars | 835M30 Round Bars

EN30B is nickel chromium molybdenum (NiCrMo) through-hardening steel. It is capable of hardening through relatively large section sizes from air cooling. It is commonly chosen for components requiring high tensile strengths in more complex machined parts.

EN30B is widely used for plastic moulds, but is also suitable for many other applications. The hardening treatment is relatively simple, quenching in air or oil from 810-830°C followed by tempering, with excellent mechanical properties being obtained. Owing to its strength this steel can be used for compression and transfer moulding as well as injection moulding and the relative freedom from distortion makes it superior to case hardening steels for complex mould applications.

835M30 steel is still often referred to as EN30B steel - its equivalent grade under the previous BS 970: 1955 standard.

Typical applications of 835M30 grade steel

• High duty gears
• Pinions
• Aero engine connection rods
• Differential shafts and other transmission components
• Airframe forgings
• Heavy roller bearings
• Breech mechanisms
• Small arms components

Applications of EN30B :

EN30B alloy steel can be used for many purposes where toughness and high tensile strength are requirements. For example: components of small presses including anvils, collars, strikers or hammers, rams or punch holders. Other applications include rivet snaps, air hardening cold chisels, crimping tools, clutch keys, racks, pinions and angle pins for pressure die casting tooling.
