Manganese Steel

Manganese Steel

The Ultimate Hard Worker

For superior wear resistance in the toughest of industrial settings, manganese steel is a must. You may have heard manganese steel called Hadfield steel or mangalloy. Our 12/14% manganese steel, also known by its brand name Creusabro M, performs brilliantly in service, whether it’s subject to high impact pressure or repeated shock.

It is fully austenitic, non-magnetic and quench annealed, which gives the metal exceptional hardness. Not only does this manganese steel arrive hard, it gets even tougher with age. Yes: the harder this metal works, the stronger it grows. Severe wear and repeated impact have a hardening effect on the steel’s structure, making it up to three times its original strength once installed and in work.

Delivered plates are typically 200 BHN, but Creusabro strengthens to an in-service hardness of at least 600 BHN when in use. It boasts a low co-efficiency of friction in metal-to-metal processes and the fact it’s non-magnetic makes it a good choice for industrial magnet machinery and electrical transformers. With such reliability and so much going for it, it’s easy to see why this high manganese steel is a favourite in construction, quarries, mining and more.

Good for:

Construction and quarries (stone chutes, chain guide and spreader plates, earth-moving crusher jaws, screen, shovel buckets, grizzly etc.)

Mining (many armouring elements, the bucket blade of loaders, sprocket wheels, conveyor chains etc.)

Foundry and iron industry (liners on shot blasting units, wear liners, flanged bolster cups, scraps containers, shifting and guiding plates.

Brickworks and concrete factories (dividing walls of parpen moulds, parpen mould core walls, mixers, paddles, grinding mill scrapers etc.)

Recovery and scrap (Strikers, hammer mills and wheel disks)

Shot blasting machinery in the automotive industries

Railways

Bicycles

How it’s made:

Manganese steel is made when steel containing around 1% carbon is alloyed (combined with) manganese. It’s important to get the level of manganese exactly right; manganese’s greatest property is its hardness, but with hardness comes brittleness. When a low percentage of manganese is added to steel, the steel becomes extremely brittle (at around 5%, it would shatter very easily). At this point, it might seem wise to add no more manganese to the steel, but in fact, increasing the amounts adds to both the hardness and ductility of the finished product. Around 13% manganese is considered to be the perfect balance for this metal to be ultra-tough but pliable too.

Benefits:
Extremely hard-wearing
Gets harder with age
Can withstand intense industrial usage
Non-magnetic

Random fact:

Mangalloy is considered to be one of the first commercially successful steel alloys. The name ‘Hadfield steel’ comes from its inventor, Robin Hadfield. In its early days, manganese steel was used for everything from bank safes to war helmets.
