Metal is a highly versatile material, used for making casters, frames, hardware, and other support systems for furniture. There’s also furniture fully made up of metal such as benches, beds, chairs, etc. All metals have inherent quality of being durable and sturdy, however some metals are preferred over others. Below is a list of metals commonly used for furniture and hardware production.
Stainless steel: It is defined as a steel alloy with a minimum of 11.5 percent chromium content. Stainless steel does not stain, corrode or rust as easily as ordinary steel. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime.
Grades of stainless steel: There are over 150 grades of stainless steel, of which 15 are most commonly used. Stainless steels are engineering materials with good corrosion- resistance, strength and fabrication characteristics. They can readily meet a wide range of design criteria, including load, service life and low maintenance. Selecting the proper stainless steel grades involves weighing four qualities in the following order of importance:
Mild steels: Carbon steel is sometimes referred to as ‘mild steel’ or ‘plain carbon steel’. Mild steel makes up the largest part of steel production and is used in a vast range of applications. Typically carbon steels are stiff and strong. Some form of protective coating is used so that it doesn’t rust if used in a corrosive environment.
Stainless steel v/s mild steel: Stainless Steel is less malleable and harder than mild steel. Mild steel is less brittle than steel. Stainless Steel is more resistant to corrosion. Mild steel can be further strengthened through the addition of carbon. The basic difference is that s/s has very little carbon and is alloyed with chromium, nickel, molybdenum and other elements to improve its mechanical and chemical properties.
