316 Stainless Steel Sheet Metal

316 stainless steel sheet metal combines high corrosion resistance, mechanical strength, and excellent formability, making it suitable for a wide range of industrial, marine, chemical, food, architectural, and medical applications. Its availability in multiple surface finishes allows it to meet both functional and aesthetic requirements, providing long-lasting performance in demanding environments.

Description

316 stainless steel sheet metal is an austenitic stainless steel widely recognized for its excellent corrosion resistance, mechanical strength, and durability. It is particularly suited for environments exposed to moisture, chemicals, and saline conditions, making it a preferred material for marine, chemical, and high-end architectural applications.

Chemical Composition

316 stainless steel includes iron, chromium, nickel, and molybdenum as key alloying elements:

Element	Typical Range (%)
Chromium (Cr)	16 – 18
Nickel (Ni)	10 – 14
Molybdenum (Mo)	2 – 3
Carbon (C)	≤0.08
Manganese (Mn)	≤2.0
Silicon (Si)	≤1.0
Phosphorus (P)	≤0.045
Sulfur (S)	≤0.03

Key Note: The addition of molybdenum significantly enhances 316’s resistance to chloride corrosion, making it superior to 304 stainless steel in harsh environments.

Mechanical Properties

Property	Typical Value
Tensile Strength	515 – 700 MPa
Yield Strength	205 – 310 MPa
Elongation	≥40%
Hardness (HRB)	70 – 90
Density	7.98 g/cm³

These properties provide excellent strength, ductility, and formability, suitable for bending, cutting, stamping, and welding.

Surface Finishes

2B Finish: Smooth and matte, ideal for industrial and processing applications.
BA (Bright Annealed) Finish: Reflective surface for decorative and architectural use.
No.4 / Brushed Finish: Linear brushed pattern for appliances, handrails, and interior panels.
HL / Hairline: Linear texture for elevator panels, wall cladding, and decorative surfaces.
