316L / Stainless Steel | Intamet Ltd
316L is a type of stainless steel with low carbon content, good corrosion resistance, and high strength.
It is commonly used in medical implants, marine equipment, and chemical processing.
316L is a type of stainless steel that is known for its excellent corrosion resistance and strength. It is commonly used in a variety of applications, including medical implants, marine equipment, and chemical processing.
One of the key characteristics of 316L is its low carbon content. This gives the steel a higher resistance to intergranular corrosion, which can occur when the steel is heated to high temperatures. Additionally, the low carbon content also makes it less prone to sensitisation, which is a phenomenon that can lead to corrosion in certain environments.
Another important feature of 316L is its high resistance to corrosion in a wide range of environments, including both fresh and salt water, as well as most chemicals. This makes it ideal for use in marine and chemical processing applications.
316L is also used in a variety of medical applications, particularly in surgical implants. The steel's biocompatibility, strength, and corrosion resistance make it well suited for use in the human body.
316L is strong and flexible, making it ideal for various manufacturing and construction uses.
316L is a strong and versatile material with low carbon content. It is highly resistant to corrosion and can be used in many different applications.
