Hardness testing to ISO 6508-1
Stainless Steel 904L, also known as UNS N08904 or 1.4539, is a high-alloy austenitic stainless steel with exceptional corrosion resistance properties. When used in the construction of eye bolts, it offers a durable and reliable solution for various applications, particularly in corrosive environments.
Machining stainless steel 904L requires conventional techniques such as cutting, drilling, and threading. However, the work hardening characteristic of this alloy can make machining somewhat challenging. Proper tools and cutting fluids must be used to maintain tool life and achieve accurate dimensions. Additionally, post-machining processes like deburring and polishing may be necessary to ensure the eye bolts meet quality standards.
Stainless Steel 904L is non-hardenable by heat treatment due to its high alloying content. Consequently, eye bolts made from 904L are typically used in their as-fabricated condition. Cold working processes, such as rolling or swaging, may be employed to increase the strength of the material while maintaining its excellent corrosion resistance.
