Suitable for application to bearing balls, outer and inner rings, and actuator rail components! *Materials available.
The "EXEO-CR20" is an original stainless steel material from Nikkoshi that has over three times the corrosion resistance compared to SUS440C. In terms of impact and bending strength, it exhibits more than twice the performance of SUS440C, achieving a tensile strength of 2200 MPa through quenching heat treatment. It has a proven track record for sliding parts that are sensitive to rust and wear in atmospheric conditions, such as rotating components and linear motion rails. 【Features】 ■ Proven track record for sliding parts that are sensitive to rust and wear in atmospheric conditions, such as rotating components and linear motion rails. ■ Can serve as a substitute for parts like SUJ2 and SCM that quickly lose their chrome plating and rust. ■ Well-suited for applications in bearing balls, outer and inner rings, and actuator rail components. ★ We provide materials that introduce performance test data and application examples. Additionally, you can also view the foundational knowledge document on stainless steel titled "Types of High-Performance Stainless Steel." ★ Please consult us regarding billets, round steel, flat steel, coil wire, polished wire, steel plates, irregular shapes, and heat-treated wire. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 - Compared to the traditionally used SUS440C, this material has 2 to 3 times stronger corrosion resistance (to acids and alkalis). - It exhibits more than double the impact and bending strength, as well as toughness compared to SUS440C. - In terms of wear resistance, it outperforms the popular SUS420J2 by more than 3 times (according to our research). - It demonstrates a tensile strength of 2200 MPa through quenching heat treatment. - Improvements in rust resistance allow for the omission of hard chrome plating on parts and products, reducing plating processes, lead times, and costs. - Compared to SUS440C, it offers 2 times better machinability and 2.5 times better grindability, enabling reductions in manufacturing time and finishing processes. *For more details, please refer to the PDF document or feel free to contact us.
