High-performance stainless steel material 'EXEO-CR20' for semiconductor and optical devices.
This material is 2 to 3 times more resistant to corrosion (acids and alkalis) compared to the traditionally used SUS440C! *Materials available upon request.
The "EXEO-CR20" is an original stainless steel material from Fujikoshi that has more than twice the toughness compared to SUS440C. Among stainless steels, it is a very hard martensitic stainless steel with hardness equivalent to SUS440C (60HRC) and has more than three times the corrosion resistance. It can be used for parts such as bolts, screw components, pins, and measuring gauges that require wear resistance and high strength. 【Features】 ■ Proven performance in parts that dislike rust and wear in semiconductor and vacuum equipment where rust-preventive oil is undesirable. ■ Applicable to device parts in optical-related equipment and mirror holders that require wear resistance. ■ Usable for parts such as bolts, screw components, pins, and measuring gauges that require wear resistance and high strength. ★ We offer materials that introduce performance test data and application examples. Additionally, you can also view the basic knowledge document on stainless steel titled "Types of High-Performance Stainless Steel." ★ Please consult us regarding billets, round bars, flat bars, coil wires, polished wires, steel plates, irregular shapes, and heat-treated wire. * For more details, please refer to the PDF document or feel free to contact us.
