FAQs About This Wire

Can Stainless Steel 316L 21 AWG Wire Be Shaped Without Heating?

It is possible to shape Stainless Steel 316L 21 AWG wire without heating, due to its inherent ductility and malleability. With this wire, you can bend, coil, and manipulate it into various shapes and forms at room temperature without heating it first. Although SS316L wire has the ability to withstand a certain degree of manipulation without becoming brittle or breaking, overworking or creating extremely tight bends can result in work hardening. This is where the wire becomes rigid and more prone to cracking as a result. The annealing process (heating followed by controlled cooling) is great to use to restore some ductility in such cases. By doing so, further work can be carried out on the material without compromising its structural integrity. Consult material and mechanical specifications to ensure the 21 AWG SS316L wire meets the specific project requirements, especially when intricate designs or a high degree of formability are required.

Is 21 AWG SS316L Wire Safe For Use In Food Industry Applications?

Yes, 21 AWG SS316L wire is generally considered safe for use in food industry applications. Stainless Steel 316L (SS316L) is recognised for its excellent corrosion resistance and is often utilized in food and beverage processing environments because it does not readily corrode, rust, or stain when exposed to food products, various substances, or even water, like many other steels can. Furthermore, SS316L does not impact the flavor of food and is resistant to acids and bases commonly found in various food items. It’s also easy to clean and sterilise, which is crucial in preventing food contamination. Nonetheless, it’s always crucial to ensure that the specific use adheres to local regulations and standards regarding materials used in food processing and handling environments. Always refer to the pertinent standards or consult a materials engineer to ensure compliance with all relevant safety and health codes for your specific application or region.

How Can I Prevent Kinks And Damage To SS316L 21 AWG Wire?


  1. Gentle Bending: Always ensure to bend the wire gently and gradually to prevent acute angles that can lead to kinks.
  2. Use Appropriate Tools: Employ tools like nylon jaw pliers that can manipulate the wire without marring its surface.
  3. Even Pressure: Apply pressure evenly when bending or shaping the wire to prevent unwanted distortions.


  1. Coil Storage: Store the wire coiled in the original packaging or on a spool to prevent unintentional bending or kinking.
  2. Avoid Overcrowding: Ensure that the storage space is not overcrowded to prevent the wire from becoming entangled or crushed with other items.
  3. Environmental Control: Store in a dry, cool place to safeguard the wire from environmental damages, like corrosion.

Work Environment

  1. Clean Workspace: Maintain a tidy workspace to prevent the wire from catching, twisting, or damaging.
  2. Proper Support: When working with longer lengths, ensure the wire is adequately supported to avoid sagging and potential kinking.
  3. Adequate Space: Ensure you have enough space to manipulate and work with the wire without constriction.


  1. Secure Packaging: When transporting the wire, ensure it is securely packaged and immobilised to prevent movement that could cause kinking or warping.
  2. Avoid Heavy Loads: Don’t place heavy items on top of the wire during transport to avoid deformation.


  1. Gradual Uncoiling: Uncoil only the needed amount of wire for use, and ensure it is done gradually to prevent sudden tangles or kinks.
  2. Avoid Force: Never force the wire to straighten or bend; instead, gently guide it into the desired shape.
  3. Periodic Inspection: Regularly inspect the wire for early signs of wear, kinks, or damage.
