Threaded Rod - Metric - A4 Stainless Steel
About Threaded Rod - Metric A4 Stainless Steel
Metric Threaded Rod is available in various grades, lengths and finishes including brass, zinc-plated and stainless steel; they are essentially a metal bar made from mild steel or brass that has a helical thread all the way along its length. Metric Rods are manufactured to be installed in areas where they are subjected to high levels of tension and pressure.
A4 Stainless is often referred to as 316 or 18/10 stainless. As in A2 Stainless Steel, the numbers 18/10 refer to the chromium and nickel content- 18% chromium and 10% nickel.
A4 stainless is often used in marine or chemical environments as it has greater corrosion resistance than A2.
The chemical composition of both A2 and A4 Stainless Steel is almost identical with the most notable differences being the higher nickel content and the addition of Molybdenum in A4. Molybdenum is a silvery-white metal that is highly corrosion-resistant, very ductile, and has an extremely high melting point.
There can also be Titanium present in A4 stainless at the option of the manufacturer.
Typically, A4 grade stainless steel costs slightly more than A2 because of its enhanced chemical and production properties. The extra cost can be justified, however, because hardware made of A4 stainless steel is extra resistant to tarnish and corrosion, enabling it to last a very long time.
