An Introduction to 416 Stainless Steel Round Bar

Do you need a stainless steel bar for a project but need help deciding which type to choose? Consider 416 stainless steel round bars. This versatile metal is commonly used in the engineering, machining, and construction industries. It’s a tough and durable material with high resistance to corrosion and wear. In this blog post, we’ll delve into the properties of 416 stainless steel and discuss why it’s a popular choice for many applications.

What is 416 Stainless Steel Round Bar?

416 Stainless Steel Round Bar is a type of martensitic stainless steel that contains ‘sulfur’ and 12-14% chromium. It exhibits excellent machinability, good corrosion resistance, and great tensile strength compared to other steels used to manufacture round bars. This makes it ideal for applications requiring high quality and superior performance.

Composition and Production of 416 Stainless Steel Round Bar

Before discussing the properties of 416 stainless steel, let’s look at its composition. This metal contains chromium and carbon and is part of the martensitic family. 416 stainless steel has a higher sulfur content than regular stainless steel, which allows it to be more easily machined. Additionally, it also contains molybdenum, which enhances its corrosion resistance.

416 stainless steel is produced by melting and refining scrap metals and adding elements like chromium, carbon, and sulfur in specific proportions. The molten metal is then solidified into a round bar shape, which can be further processed into various sizes by hot-rolling or cold-drawing.

Physical and Mechanical Properties

416 stainless steel has a 7.75 g/cm3 density, making it relatively lightweight and easy to work with. It has a high tensile strength of 620 MPa and a yield strength of 415 MPa, meaning it can withstand high stress loads without bending or breaking. Its high hardness of 241 HBW also makes it resistant to scratches and wear.

Regarding thermal and electrical conductivity, 416 stainless steel performs poorly compared to other metals. However, it has excellent corrosion resistance, even in harsh environments like marine or chemical processing facilities. Additionally, its machinability is superior to other stainless steel alloys due to its high sulfur content.

Applications of 416 Stainless Steel Round Bar

Due to its combination of high strength, hardness, and corrosion resistance, 416 stainless steel finds many applications across different industries. Its machinability makes it a popular choice for machining tools, bolts, screws, and other components that require precision and durability. Its corrosion resistance also makes it suitable for marine equipment, chemical processing plants, and food processing machinery.

416 stainless steel is also used in the construction industry for building parts that require a combination of strength and corrosion resistance, like door handles, railings, and lighting fixtures. Its magnetic properties make it a good choice for manufacturing electrical components like transformers and chokes

Benefits and Limitations

One of the primary benefits of 416 stainless steel is its high machinability, which allows for easy manufacturing of precise components. Additionally, its resistance to wear and corrosion ensures a long service life for parts made from this metal. It’s also relatively cost-effective compared to other high-performance metals like titanium or nickel alloys.

One limitation of 416 stainless steel is its poor performance in high-temperature environments. It’s unsuitable for applications requiring elevated temperatures due to its low thermal conductivity and thermal expansion coefficient. Its poor electrical conductivity also makes it unsuitable for electronic applications.


stainless steel 416 round bar is a reliable and versatile material with high demand in several industries. Its unique combination of strength, hardness, and corrosion resistance makes it a popular choice for machining, construction, and engineering applications. Its composition and production are straightforward, making it cost-effective compared to other high-performance metals. Although it has some limitations in extreme environments, its overall benefits make it a great choice for many different projects.
