Detailed Engineering Specifications

Built to exacting engineering tolerances, this 304 stainless steel stock sheet measures 0.187 inches in thickness, with a nominal length of 21 inches and a width of 19 inches. Fabricated from Type 304 stainless steel, it offers excellent corrosion resistance, particularly against atmospheric and many organic and inorganic chemical compounds. This grade is non-magnetic in the annealed condition and provides good strength and formability, making it ideal for use in applications requiring resistance to wear and surface degradation, such as custom grinding fixtures, polishing platens, and die-cutting surfaces.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong grit abrasive for the desired finish.Consult abrasive manufacturer's guidelines or perform test runs to select the appropriate grit for the specific polishing or abrading task.
Applying excessive force during polishing, leading to overheating or uneven surface treatment.Employ controlled pressure and consistent movement. Allow the abrasive and the material to do the work, and consider using cooling lubricants if necessary.

Common Applications

  • Custom grinding fixture fabrication
  • Polishing platen construction
  • Die-cutting surface manufacturing

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling and working with metal sheets.
  • Ensure proper ventilation in areas where abrading or polishing operations are performed to manage dust and fumes.
