Stainless steel 'STAVAX ESR' for plastic molds
It is a plastic mold steel with excellent mirror finish, machinability, and corrosion resistance, backed by many years of proven performance!!
"STAVAX ESR" is a high-performance, precision stainless steel for plastic molds, developed by Uddeholm in Sweden, with a pre-hardened hardness of 30HRC. It has excellent corrosion resistance, superior polishability, machinability, and dimensional stability, surpassing SUS420J2. Additionally, due to its excellent resistance to pitting corrosion, it is less prone to stress corrosion cracking, which is a concern with SUS420 series steels. Manufacturer: Uddeholm 【Features】 ■ Stainless steel pre-hardened steel (ESR material) with a hardness of HRC 27-35 upon delivery ■ Excellent corrosion resistance exceeding SUS420J2, along with good polishability, machinability, and dimensional stability ■ Additional heat treatment can achieve a maximum hardness of 53HRC, allowing for excellent mirror finish (#12000) ■ Excellent resistance to pitting corrosion, making it less susceptible to stress corrosion cracking, which is a problem with SUS420 series steels *For more details, please refer to the PDF document or feel free to contact us.
