Stainless steel 13-8Mo flanges are an excellent choice for high strength, corrosion resistance, and mechanical properties. These flanges are produced from martensitic precipitation-hardening stainless steel and exhibit excellent corrosion resistance and high tensile strength. They also offer good toughness and fatigue resistance.
Features of Stainless Steel 13-8Mo Flanges
Stainless Steel 13-8Mo flanges are martensitic precipitation-hardening stainless steel flanges known for their high strength, corrosion resistance, toughness, and fatigue resistance. The 13-8Mo flanges have a combination of high tensile strength and good toughness, enabling them to be used in critical applications. They are resistant to corrosion in both oxidizing and reducing media.

Corrosion Resistance of Stainless Steel 13-8Mo Flanges
Stainless Steel 13-8Mo flanges are also known for their excellent corrosion resistance. They can withstand corrosion in both oxidizing and reducing environments. The flanges resist intergranular corrosion, stress corrosion cracking, and pitting corrosion. That makes them an ideal material for applications where high corrosion resistance is necessary. They also exhibit excellent resistance to sulphide stress corrosion cracking caused by hydrogen sulphide.
Chemical Composition of Stainless Steel 13-8Mo Flanges
The chemical composition of Stainless Steel 13-8Mo flanges includes iron, chromium, nickel, molybdenum, cobalt, and carbon. Adding molybdenum and cobalt enhances the flanges' corrosion resistance and mechanical properties. The chemical composition of 13-8Mo steel is such that it exhibits good ductility and toughness after precipitation hardening. This steel is known for its high strength and toughness, making it ideal for high-stress applications.
Heat Treatment of Stainless Steel 13-8Mo Flanges
Stainless Steel 13-8Mo flanges are precipitation-hardened steel, which means they undergo heat treatment to achieve high strength and toughness. They require a two-step heat treatment procedure: solution treatment followed by precipitation hardening. The solution treatment is carried out at high temperatures to dissolve the original structure of the steel. Then the flanges are rapidly cooled to room temperature before undergoing the precipitation hardening stage. Precipitation hardening increases the strength of the material and enhances its mechanical and corrosion resistance properties.
