No3.Best Value for Money

 In recent years, researchers and producers (including MnSteels) have made numerous attempts to improve performance of manganese steels for different applications by modifying conventional composition and applying different heat treatment techniques.

• It would be worth mentioning here that most of the field failures or poor performance of manganese steels of standard composition are not due to inherent short-comings of the choice of composition or heat treatment, but due to ignorance about the metallurgy of the steel and carelessness / casualness during manufacturing stage.

• MnSteels has been producing manganese steel for twenty years, experience indicates that, except in some special applications, standard manganese steel, if manufactured with necessary controls, gives better performance in most of the wear conditions, compared to costly variations.

With the increase demand of austenitic manganese steel castings all over the world, innumerable foundries, big or small, professional or armature, produce manganese steel castings today. As a result there has been a wide scatter in the performance of standard austenitic manganese steel castings. This is because, except a few, most of the foundries do not have knowledge of metallurgy of manganese steel and not aware of the strict controls required to produce good quality manganese steel castings. And when complaints start coming from the users or the performance is compared with the products of the few good foundries, most foundries, almost blindly, start trying different modifications of manganese steels with different costly alloys, instead of trying to improve the manufacturing process.

MnSteels has always been trying to produce "proper" manganese steel castings; quality control and process management play a very important role in our day to day tasks.

With the proper procedures applied, MnSteels castings carry the following benefits:

• Longer wear life

• Fast work-hardening properties

• Reliable change-out scheduling/ consistent service life

• Reduced downtime through less change-outs
