Description

Introduction

409L stainless steel sheet, a type of ferritic stainless steel, is widely used in various industries, ranging from automotive to food and beverage. Its versatility, excellent corrosion resistance, and formability make it a highly sought-after material. In this comprehensive discussion, we delve into the composition, physical properties, **mechanical properties, and uses of 409L stainless steel.

Physical Properties:

409L grade stainless steel exhibits a density of 7.86 g/cm³ and a melting point range spanning between 1390-1450 °C. Noteworthy attributes include an elongation at breakage of 22%, commendable thermal conductivity, and a low thermal expansion coefficient. These characteristics render it suitable for deployment in **high-temperature environments**, particularly in automotive exhaust systems.

Mechanical Properties:

As a ferritic material, 409L stainless steel sheet is characterized by low ductility and limited weldability compared to austenitic counterparts like 304 or 316 grades. Its mechanical properties encompass a tensile strength of 360-550 MPa and a yield strength of 170-380 MPa.
