Chemical composition

Physical properties

Material properties

UNS J91249, classified under ASTM A128 Grade E-1, is a high manganese austenitic steel known for its superior durability and exceptional wear resistance. This steel grade is distinguished by its high manganese content, which significantly enhances its hardness and makes it highly resistant to wear in severe impact conditions. Its excellent toughness and high ductility make it ideal for products requiring resistance to both high stress and high impact. UNS J91249 is especially effective in environments where other materials might suffer from rapid degradation. Its high resistance to deformation under heavy loads makes it a popular choice for industries requiring reliable performance under extreme conditions. Additionally, its capacity to harden upon impact continuously extends the life of components made from this steel, thereby reducing maintenance costs and downtime in industrial applications.

Advantage

1.Exceptional high impact resistance.
2.Continuous hardening with impacts.
3.High wear resistance.
4.Reduces maintenance and downtime.
5.Extends component life significantly.

Application

UNS J91249 steel is widely utilized in sectors where high strength and resistance to impact wear are mandatory. It is commonly employed in the production of crushing equipment for mining and aggregate industries, where its ability to withstand severe impact is critical. Additionally, it is used in the manufacture of railway components that must resist heavy loads and harsh environmental conditions. Other applications include heavy-duty machinery components and wear-resistant castings used in construction and heavy industry. This steel's high durability and wear resistance make it an essential material for applications involving extreme mechanical stress and wear.
