Stainless Steel External Levers

Stainless Steel External Levers

When choosing a stainless steel external door lever, it is important to know the differences between each grade of steel and how this will affect their performance under different environmental conditions. The two most common grades of stainless steel used for door levers are 304 and 316. Despite being indistinguishable in appearance, each grade holds unique characteristics that will make them better suited to specific applications.

The chemical composition of each grade is what will affect their overall performance under harsh conditions. 304 Grade Stainless Steel contains 18% chromium and 8% nickel, while 316 contains 16% chromium, 10% nickel, and 2% molybdenum. The molybdenum is added to help prevent corrosion from chlorides and other common chemicals such as oxygen (the main cause of surface rust for metals containing iron).

Key differences between Grade 304 and 316 Stainless Steel door levers:

  • Cost
    Grade 316 Stainless Steel levers cost more than Grade 304, due to the elements that make up the overall material. Despite both being primarily made up of iron, the added molybdenum (which helps prevent corrosion) in Grade 316 puts the price up as it is an expensive element to include.
  • Corrosion Resistance
    Stainless steel as a group of metals is highly corrosion resistant but with the addition of molybdenum into 316, this increases the grades ability to withstand harsh environments. Often referred to as “Marine Grade”, 316 levers are suitable for use in more extreme environments e.g. coastal areas, although care should still be taken to clean the product regularly to prolong its product life. Grade 316 levers are also resistant against chlorine, which 304 are not.
