![]() How Well Do Stainless Steel and Galvanized Steel Conduct Heat?īoth stainless steel and galvanized steel should conduct heat in a relatively similar manner. These contain higher amounts of nickel, making them more formable for larger objects like sinks, basins, and tanks. If you must use stainless steel and want greater malleability but aren’t sure how to pick the perfect stainless steel grade, consider austenitic grades. This means that in most cases, it will be more malleable than comparably shaped stainless steel forms. Galvanized steel offers the same malleability as the underlying steel used. How Malleable are Stainless Steel and Galvanized Steel? More alloyed metals or a thicker coating will result in greater weight. The specific differences will vary depending on the exact stainless steel alloys in question and the zinc coating thickness on the galvanized steel product. ![]() In most cases, stainless steel and galvanized steel will have a very similar weight. Is Stainless Steel Heavier than Galvanized Steel? Since galvanization does not impact the tensile strength of the underlying metal, you could reasonably expect galvanized steels made from various steel grades to have comparable tensile strength compared to the original steel. Structural steel has a tensile strength of 400 megapascals (MPa), while carbon steel has a tensile strength of 841 megapascals (MPa).īoth are commonly used for creating galvanized steel productions. The tensile strength of stainless steel alloys typically starts around 515 megapascals (MPa) and can reach as high as 1300 megapascals (MPa) in some cases. Tensile strength is the resistance of a material to breaking under tension.Įxact figures will vary by the alloy in use. When compared at similar thicknesses and forms, stainless steel is always stronger than galvanized steel.Īn effective way to compare this is by looking at the tensile strength of each material. Which is Stronger: Galvanized or Stainless Steel? In general, stainless will offer better corrosion resistance and offer it for a longer period as well. ![]() However, even if the zinc layer on a galvanized component is damaged, it will still serve as a sacrificial cell in galvanic corrosion processes, encouraging rust formation on the damaged zinc areas instead of the underlying steel. This means that over extended periods, galvanized parts are generally less durable than stainless ones. The protective layer on galvanized is also not self-healing like the passive layer on stainless steel. Galvanized steel offers excellent resistance against water and chlorine but pales in comparison to stainless steel’s corrosion resistance when dealing with marine environments. However, this will depend on the specific situations in which you plan to use your galvanized or stainless steel parts. So Is Galvanized Steel as Corrosion Resistant as Stainless Steel? This also means that you end up with a layered finished product instead of a fully alloyed product like stainless steel. This layer of zinc serves the same purpose as the passive layer of chromium oxide on the surface of stainless steel, helping the metal resist corrosion and repel scuffs, dings, and other minor physical abuses. In this process, standard steel is dipped in molten zinc, creating a layer of zinc that bonds with the surface of the steel, providing protective benefits and an appealing appearance.Įlectro-dipping and thermal diffusion methods are also used when parts are particularly small or complex. The most common method of galvanizing steel is hot-dipping. There are multiple ways to galvanize steel parts and components, but they all provide similar results as long as they are correctly performed. What is Galvanized Steel Anyhow?īefore we can compare them, it’s essential to understand how galvanized steel is made.Įssentially, galvanized steel is simply zinc-plated steel. In this guide, we’ll compare stainless steel and galvanized steel across a variety of common considerations and use types to help highlight the strengths and weaknesses of these two popular steel variations. So which is better for your next project? However, these are all key traits of stainless steel as well. Galvanization is a process designed to help steel resist corrosion and provide protection to keep it looking and performing great.
