AM 355 stainless steel is a martensitic stainless steel that is known for its high strength and toughness. It is also known for its good corrosion resistance, making it a popular choice for a variety of applications.

AM 355 stainless steel is composed of approximately 18% chromium and 8% nickel, with small amounts of molybdenum, silicon, and carbon. It is classified as a martensitic stainless steel because it has a relatively high level of hardness and strength compared to other stainless steel alloys.

One of the main benefits of this stainless steel is its high strength. It has a tensile strength of over 1200 MPa, making it one of the stronger stainless steel alloys available. This high strength makes it ideal for use in structural applications, such as in the construction of bridges and buildings.

In addition to its high strength, it also has good corrosion resistance. It is resistant to a variety of corrosive environments, including seawater and acidic solutions. This makes it a popular choice for use in marine and chemical processing applications.

PYROMET 355 stainless steel can be welded and formed using standard techniques, making it easy to work with. It can be heat treated to increase its strength and hardness, or it can be left in its as-welded condition for a softer, more ductile material.

Overall, AM 355 stainless steel is a strong, corrosion-resistant alloy that is well-suited for a wide range of applications. It is often used in structural applications, marine environments, and chemical processing plants.
