Tinned Steel Wire Mesh – Alloy Overview
Tinned steel wire mesh was once widely used in the food processing industry, but in recent years has been nearly entirely replaced by the use of T-410 stainless, T-410L stainless, and T-430 stainless wire mesh (due to their magnetic properties). The process of tinning steel involves taking low carbon steel wire and thinly coating the wire with a layer of tin (known as tinplate). The tinplate offers an additional layer of protection for the low carbon steel wire against rust. Primarily comprised of iron, low carbon grades 1005, 1006, and 1008 are the most frequently used, and contain small percentages of carbon (0.0-0.1%), manganese (0.0-0.5% – which increases its strength), phosphorous (0.0-0.04%), and sulfur (0.0-0.05%). Some characteristics of the alloy which dictate its use are:
- Low carbon plain steel alloy.
- Relatively low cost and high strength material.
- Magnetic in all conditions.
- Tinplate layer helps prevent rusting.
- Commonly replaced by T-410, T-410L and T-430 stainless steels today.
- Can be cut, formed, and welded.
Industries & Applications
Tinned steel wire mesh was a primary choice by many in the food industry for a number of years. Today, most users have transitioned to using T-410, T-410L, or T-430 stainless steel wire mesh given their superior corrosion resistance and good magnetic properties.
