AISI Type 205 stainless steel is an Austenitic Standard grade Stainless Steel. Grade 205 stainless steel is an austenitic standard grade.

It is commonly called AISI Type 205 Chromium-Manganese-Nickel steel. It is composed of (in weight percentage) 0.12-0.25% Carbon (C), 14.0-15.5% Manganese (Mn), 1.00% Silicon (Si), 16.5-18.0% Chromium (Cr), 1.0-1.75% Nickel (Ni), 0.06% Phosphorus (P), 0.03% Sulfur (S), 0.32-0.40% Nitrogen (N), and the base metal Iron (Fe). Other designations of AISI Type 205 stainless steel include UNS S20500 and AISI 205.

It is also referred to as AISI Type 205 Chromium-Manganese-Nickel steel. Grades such as the 205-series provide approximately 30% higher mechanical properties such as yield strength than the traditional 304-series. These grades also provide good formability and ductility.

Grade 205 stainless steel is a widely used precipitation hardening grade steel. It possesses good corrosion resistance, high harness, toughness and strength. In solution annealed condition, it is soft and ductile; however it is capable of high properties with a single precipitation or aging treatment.

205 stainless steel Manufacturing Process

The machinability of grade 205 stainless steel produces long, gummy chips. Machining can be performed in the annealed condition. For heat treatment, soak the material at 1038°C (1900°F) for 30 min and cool below 16°C (60°F) for complete martensite transformation. The material can be welded by common fusion and resistance methods; however, it is recommended that this steel should not be joined using oxyacetylene welding method. The recommended filler metal is AWS E/ER630.

The typical elastic modulus of stainless steels at room temperature (25°C) ranges from 190 to 210 GPa. The typical density of stainless steels ranges from 7.75 to 8.1 g/cm3. The typical tensile strength varies between 515 and 827 MPa. The wide range of ultimate tensile strength is largely due to different heat treatment conditions.
