This table outlines the typical ranges of the major alloying elements in 316 stainless foil. Please note that these percentages may vary slightly depending on the specific manufacturing standards or requirements of a particular product or supplier.
316 Stainless Steel Foil Mechanical Properties
The mechanical properties of grade 316 foil are summarized in the following table:
Mechanical Properties | Tensile Strength | Yield Strength | Elongation | Hardness |
|---|---|---|---|---|
| Typical Value | 75,000 – 85,000 psi | 30,000 – 35,000 psi | 40% min | Around 95 HRB or less |
These mechanical property parameters describe how 316 stainless steel foil behaves when subjected to stress. Yield strength is the point at which a material begins to deform, while tensile strength indicates the maximum tensile load a material can withstand. Elongation indicates how much a material can stretch when stretched. Hardness indicates the material’s resistance to scratches and pressure.
Please note that the mechanical property parameters of specific products may vary depending on manufacturing standards, processing conditions, and suppliers.
316 Stainless Steel Foil Physical Properties
| Property | Value |
|---|---|
| Density | 7.98 g/cm³ |
| Melting Point | 1,370°C – 1,390°C |
| Thermal Conductivity | 16.3 W/(m·K) |
| Coefficient of Linear Expansion | 16.5 x 10^-6/°C |
| Electrical Conductivity | 1.25 x 10^6 S/m |
| Modulus of Elasticity | 193 – 200 GPa |
These physical property parameters describe the behavior of 316 stainless foil under various physical conditions. Density is the ratio of a substance’s mass to its volume, usually expressed in grams per cubic centimeter (g/cm³). The melting point is the temperature at which a material changes from a solid to a liquid state. Thermal conductivity represents a material’s ability to conduct heat, while the coefficient of linear expansion describes the dimensional changes in a material as temperature changes. Conductivity measures a material’s ability to conduct electricity.
Please note that these values are typical physical property parameters of 316 stainless steel and actual values may vary depending on manufacturing standards, processing conditions, and specific alloy composition.

How To Make 316 Stainless Steel Foils?
Manufacturing 316 stainless steel foils involves a series of processes to transform stainless steel into thin, flat sheets or strips. Here’s a general overview of how 316 stainless steel foils are made:
- Raw Materials: The process begins with the selection of high-quality stainless steel alloy, typically Type 316, which contains specific amounts of chromium, nickel, molybdenum, and other elements.
- Melting: The chosen stainless steel alloy is melted in an electric arc furnace or an induction furnace. During this process, various alloying elements may be added to achieve the desired composition.
- Casting: The molten stainless steel is cast into thick slabs or billets. These slabs are then hot-rolled to reduce their thickness.
- Hot Rolling: The slabs are heated and passed through a series of rolling mills to reduce their thickness further. This hot-rolling process can be repeated several times until the desired thickness is achieved.
- Cold Rolling: After hot rolling, the stainless steel strips go through a cold rolling process. Cold rolling involves passing the material through rollers at room temperature to further reduce its thickness and improve surface finish. This process may also involve annealing (heat treatment) to enhance the material’s properties.
- Annealing: Stainless steel foils are often subjected to an annealing process to relieve stress, improve ductility, and enhance their mechanical properties. Annealing involves heating the material to a specific temperature and then slowly cooling it.
- Trimming and Slitting: The stainless steel strip is trimmed to the desired width, and then it can be slit into narrower foils if needed.
- Surface Treatment: Surface treatments such as pickling, passivation, or polishing may be applied to improve the appearance and corrosion resistance of the stainless steel foils.
- Quality Control: The finished foils undergo stringent quality control checks to ensure they meet the required thickness, mechanical properties, and surface finish specifications.
- Coiling and Packaging: The stainless steel foils are coiled and packaged according to customer specifications for transportation and storage.
It’s important to note that the specific manufacturing processes and equipment used can vary between manufacturers and regions. Quality control and adherence to industry standards are essential throughout the production process to ensure the consistent quality of 316 stainless steel foils.

FAQ – 316 Stainless Steel Foil
What is the difference between 316 stainless steel foil and 316L stainless steel foil?
316L is a low-carbon version of 316 (L stands for Low Carbon). 316 stainless steel foil has a maximum carbon content of 0.08%, while 316L stainless steel foil has a maximum carbon content of 0.03%. In welding applications, 316L effectively prevents intergranular corrosion, making it a better choice for welding applications. Huaxiao Metal manufactures and offers both grades in stock.
How do you guarantee the quality of your 316 stainless steel foil as a manufacturer?
As a professional 316 stainless steel foil manufacturer, we implement a rigorous five-step quality inspection process: raw material spectral analysis, online thickness measurement during cold rolling, surface inspection after bright annealing, finished product mechanical property testing, and final inspection before shipment. All products come with an MTC report to ensure compliance with customer specifications and international standards.
