AISI Type 414 is a Martensitic Standard grade Stainless Steel. It is commonly called AISI Type 414 Chromium steel. It is composed of (in weight percentage) 0.15% Carbon (C), 1.00% Manganese (Mn), 1.00% Silicon (Si), 11.5-13.5% Chromium (Cr), 1.25-2.50% Nickel (Ni), 0.04% Phosphorus (P), 0.03% Sulfur (S), and the base metal Iron (Fe). Other designations of AISI Type 414 stainless steel include UNS S41400 and AISI 414.

Steel is the common name for a large family of iron alloys. Steels can either be cast directly to shape, or into ingots which are reheated and hot worked into a wrought shape by forging, extrusion, rolling, or other processes. Wrought steels are the most common engineering material used, and come in a variety of forms with different finishes and properties. Stainless steels are high-alloy steels that have superior corrosion resistance than other steels because they contain large amounts of chromium. Stainless steels contains at least 10% chromium, with or without other elements. Stainless steels can be divided into three basic groups based on their crystalline structure: austenitic, ferritic, and martensitic.
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.
