What is the Temperature Resistance of Different Steel Types?

When it comes to high-strength construction materials, few come close to what steel can provide. Being the main material of choice for a wide variety of building and infrastructure projects, steel has provided builders with a material that can withstand various elements and has the ability to be versatile enough to adjust to different techniques and scenarios. Compared to materials such as wood and stone, steel can adjust to different shapes and sizes much easier, which is another reason why it has become a very popular material to use.

What is the Temperature Resistance of Different Steel Types?

Steel has long been recognized as one of the strongest building materials. With the ability to withstand high impact and heavy weight, along with being very flexible and versatile, steel is very reliable to use and handle. Another important quality of steel is it has a high temperature resistance, allowing it to be used in the industrial and construction industries, along with being used to create products. Let us take a look at the different steel types and their temperature resistance.

304 Steel

304 Steel

One of the most common types of stainless steel, 304 steel is known for its high nickel and chromium content, making it highly resistant to corrosion. This makes it an ideal steel material to be used in products and machinery such as home appliances, heat exchangers, steel piping, food processing equipment, and steel fasteners. This makes 304 steel highly resistant to high temperatures, with an Intermittent maximum temperature of 870 degrees Celsius, and a Continuous maximum temperature of 925 degrees Celsius.

309 Steel

Compared to 304 steel, 309 steel has a high resistance to corrosion, which means that it also has a higher temperature resistance that makes it viable to be used for different types of machinery. 309 steel is used to create high-temperature machinery and equipment like oven linings, firebox sheets, and components for steel furnaces. 309 steel has an intermittent maximum temperature of 980 degrees Celsius, and a continuous maximum temperature of 1095 degrees Celsius.

310 Steel

310 Steel

Another steel type commonly used in high-temperature tools, equipment, and machinery, 310 steel is known for retaining strength at extreme levels of temperature. This quality also makes it resistant to corrosion, oxidation, and sulfidation, making it ideal for tools and equipment such as burner tips, flare tips, heat exchangers, refractory anchors, heat treatment baskets, and jigs. 310 steel has an intermittent maximum temperature of 1035 degrees Celsius, and a continuous maximum temperature of 1150 degrees Celsius.

316 Steel

Similar to 304 steel, 316 steel has a high amount of chromium and nickel. Along with chromium and nickel, it also contains elements like silicon, manganese, carbon, and molybdenum. Along with being resistant to corrosion, 316 steel is also resistant to various liquids. This makes it ideal for products and machinery such as medical equipment, chemical manufacturing and storage, and marine tools and equipment. Being similar to 304 steel, 316 steel also has the same temperature resistance, with an intermittent maximum temperature of 870 degrees Celsius, and a continuous maximum temperature of 925 degrees Celsius.

321 Steel

321 Steel

A strong and light steel that contains titanium, 321 steel has high carbon content that makes it resistant to extreme temperatures. This also makes the steel resistant to interangular corrosion, which makes it great to use in a number of hot environments. While it’s temperature resistance is not as strong as the other aforementioned steel types, 321 steel is still used to manufacture tools and equipment such as bellows, aircraft exhausts, welded processing screens, and furnace parts. 321 steel has an intermittent maximum temperature of 870 degrees Celsius, and a continuous maximum temperature of 925 degrees Celsius.

410 Steel

A general-purpose steel type, 410 steel is strengthened using techniques like polishing, tempering, and hardening. This allows it to have good corrosion resistance and tensile strength. While it is a steel that is popularly used, it has a lower temperature resistance compared to other steel types. 410 steel has an intermittent maximum temperature of 815 degrees Celsius and a continuous maximum temperature of 705 degrees Celsius.

420 Steel

420 Steel

A high-carbon steel that can be strengthened further using heat treatment, 420 steel has qualities like corrosion resistance and good ductility. This makes it an ideal type of steel to use for tools and equipment like cutlery, shear blades, needle valves, and medical equipment. 420 steel has an intermittent maximum temperature of 735 degrees Celsius, and a continuous maximum temperature of 620 degrees Celsius.

Key Takeaway

Steel is not only very durable, but it is also resistant to high temperatures and corrosion, making it ideal for different industries and machinery applications. By identifying the temperature resistance, you will be able to pick the right type of steel to use for your industrial projects.
