AISI AISI 414

Profile

This page is mainly introduced the AISI 414 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AISI 414,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
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.
