409L Stainless steel round rod

409L stainless steel is categorized as ferritic steel that is highly resistant to corrosion and high temperature with superior mechanical properties. It contains around 11% chromium, which is the minimum amount required to form the passive surface film that makes stainless steel resistant to corrosion.

PRODUCT DESCRIPTION

409L Stainless steel round rod Description

409L stainless steel is distinguished from other types of stainless steel for its chemical composition. Iron, with large amounts of chromium and small amounts of carbon, manganese, silicon and nitrogen compose this material. Iron is the primary element of 409L stainless steel, providing its strength and stability. Chromium accounts for its corrosion resistance and helps form a protective oxide layer on the surface. Carbon helps increase the hardness and wear resistance. Manganese acts as a stabilizer to prevent excessive grain growth during heat treatment. Silicon enhances oxidation resistance while preventing scaling at high temperatures. Nitrogen improves mechanical properties such as tensile strength and yield strength. This unique combination of elements gives 409L stainless steel excellent thermal expansion capabilities, making it suitable for high-temperature applications without compromising its structural integrity or dimensional stability. Its chemical composition also provides good solderability, thus simplifying the manufacturing process.
