Introduction to 410L stainless steel plate

Introduction

410L is a ferritic stainless steel primarily composed of iron, with chromium and carbon as key alloying elements. As the variant with the lowest carbon content in the 410 series, 410L offers superior weldability and high ductility, making it suitable for manufacturing complex-shaped components.

Chemical Composition of 410L Stainless Steel Plate

Chromium (Cr): 11.5%-13.5%

Carbon (C): ≤0.03%

Manganese (Mn): ≤1.0%

Silicon (Si): ≤1.0%

Phosphorus (P): ≤0.040%

Sulfur (S): ≤0.030%

Nickel (Ni): Trace amounts

Chromium is the principal element that imparts corrosion resistance to 410L stainless steel. The low carbon content (≤0.03%) enhances weldability. Other elements like manganese, silicon, phosphorus, and sulfur are present in minor quantities, each influencing the steel’s properties to some extent.

Mechanical Properties of 410L Stainless Steel Plate

Tensile Strength: Typically between 440-520 MPa

Yield Strength: Generally ranges from 205-225 MPa

Elongation: Around 18%-20%, indicating good plastic deformation capability

Hardness: Approximately 210-220 HB (Brinell hardness), depending on heat treatment

Impact Toughness: Generally low, around 20-40 J/cm²

It is essential to note that these mechanical properties can vary based on manufacturing processes, heat treatment, and precise chemical composition. For accurate mechanical properties, consulting manufacturer datasheets or professional advice is recommended.
