ASME SA268 TP405 UNS S40500 Ferritic Stainless Steel Pipes & Tube
Ferritic Stainless Steel – Grade 405 (UNS S40500)
Stainless steels are known as high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steels.
Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.
The chromium content in grade 405 stainless steel is 12%. The following datasheet provides an overview of grade 405 stainless steel.
The chemical composition of grade 405 stainless steel is outlined in the following table.

Material magnetic in all conditions.
AISI Type 405 is a martensitic stainless steel that provides high strength and hardness with moderate corrosion resistance. A wide range of properties can be developed with different heat treatments, with ultimate tensile strengths ranging from 500 to 1400 MPa. It is magnetic in both the annealed and hardened conditions. High carbon content results in the formation of chromium carbide compounds, providing excellent wear resistance and edge retention when hardened. Additionally, this grade provides excellent high temperature oxidation and scaling resistance, yet is economical due to the low alloy content. Thermal conductivity is improved and thermal expansion reduced relative to austentic stainless grades.
