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.


  • Corrosion Resistance: Stainless Steel 904L is renowned for its exceptional resistance to a wide range of corrosive media, including sulfuric acid, chloride, and other aggressive chemicals. This makes it an ideal material for eye bolts used in harsh and corrosive environments such as marine and chemical industries.
  • High Strength: 904L stainless steel maintains excellent mechanical properties even at elevated temperatures. Its high tensile strength and hardness ensure that eye bolts made from this material can withstand substantial loads and maintain structural integrity.
  • Machinability: Stainless Steel 904L can be machined, welded, and fabricated relatively easily, making it suitable for the production of complex and custom-designed eye bolts.

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.

Heat Treatment:

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.
