Excellent Durability:Wear-resistant steel grades such as NM400TUF and NM500TUF have hardness ranging between 370 HBW and 500 HBW (Brinell hardness). This can increase surface hardness and durability, extending product life up to 4 times that of conventional structural steels in high-wear environments, reducing replacement frequency and costs.
High Toughness: GNEE’s high-toughness steels have excellent impact resistance, with Charpy V-notch impact values exceeding 40 J/cm² at temperatures as low as -40°C. This level of impact toughness helps resist cracking and chipping under heavy loads, providing reliable performance even in sub-zero conditions.
Lightweight and High Strength:The yield strength is 700–1300 MPa, depending on the grade, while maintaining a small material thickness. This can reduce part weight by 50% compared to conventional steels with a yield strength of 345 MPa.
Customizable Options:Thicknesses range from 3mm to 25mm to accommodate a wide range of industrial applications, from thin sheets for car bodies to thick plates for wear parts in heavy machinery.
