High Performance 445 Stainless Steel Sheet: Corrosion-Resistant,
Durable & Versatile
Overview of 445 Stainless Steel Sheet
The 445 Stainless Steel Sheet is a high-performance, corrosion-resistant material widely used in
various demanding industrial applications. Known for its excellent
resistance to oxidation, high temperature stability, and overall
durability, this ferritic stainless steel is ideal for environments
exposed to harsh conditions such as high temperatures, corrosive
chemicals, and mechanical stress.
445 stainless steel is a popular choice for industries ranging from
automotive to chemical processing, food manufacturing, and heat
exchangers. Its combination of strength, corrosion resistance, and
weldability makes it a versatile option for both structural and
aesthetic applications.
Key Features of 445 Stainless Steel Sheet
Corrosion Resistance
Alloy 445 offers outstanding resistance to general corrosion,
especially in environments where exposure to chemicals such as
chlorides and sulfur compounds is a concern. This makes it an ideal
material for industries that require reliable, long-lasting
performance in corrosive settings.
High-Temperature Resistance
This alloy maintains good mechanical properties at elevated
temperatures, making it a suitable choice for applications that
involve heat exchange or high-temperature processes. The alloy’s
ability to resist oxidation at temperatures up to 950°C (1,742°F)
is one of its key advantages.
Durability and Strength
445 stainless steel is highly resistant to thermal fatigue and
stress, providing excellent long-term performance in demanding
environments. Its ability to withstand mechanical stress without
losing its structural integrity contributes to its reliability in
critical applications.
Weldability
Alloy 445 is highly weldable compared to other ferritic alloys. It
maintains its strength and corrosion resistance after welding,
making it an ideal material for welded structures and components.
Versatility
With its 2B surface finish, the 445 stainless steel sheet is not only functional but also aesthetically appealing. Its
smooth, polished surface makes it suitable for decorative purposes
in addition to industrial uses.
Chemical Composition of 445 Stainless Steel Sheet
The chemical composition of 445 stainless steel plays a crucial role in its excellent corrosion resistance,
high-temperature performance, and overall durability. The primary
elements found in this alloy include:
| Element | Percentage (%) |
|---|
| Chromium (Cr) | 16.0 – 18.0% |
| Carbon (C) | ≤ 0.03% |
| Manganese (Mn) | 0.50 – 1.00% |
| Silicon (Si) | 0.30 – 1.00% |
| Phosphorus (P) | ≤ 0.03% |
| Sulfur (S) | ≤ 0.03% |
| Nickel (Ni) | ≤ 0.50% |
| Iron (Fe) | Balance |
This composition gives 445 stainless steel its excellent resistance
to oxidation and corrosion, particularly in environments exposed to
elevated temperatures and aggressive chemicals.
Mechanical Properties of 445 Stainless Steel Sheet
The mechanical properties of 445 stainless steel ensure its performance under mechanical stress, high temperatures,
and exposure to corrosive environments. Below are the key
mechanical characteristics:
| Property | Value |
|---|
| Yield Strength | 200-250 MPa |
| Tensile Strength | 450-600 MPa |
| Elongation | ≥ 20% |
| Hardness (Rockwell B) | 80 HRB |
| Density | 7.75 g/cm³ |
| Modulus of Elasticity | 200 GPa |
| Poisson’s Ratio | 0.30 |
These properties demonstrate that the 445 stainless steel sheet can
withstand significant mechanical forces without compromising its
performance, making it ideal for applications in structural and
industrial components.
Industry Standards for 445 Stainless Steel Sheet
445 stainless steel sheet adheres to several international
standards, ensuring quality, performance, and compatibility across
a wide range of applications. The most relevant standards for 445
stainless steel include:
EN 10204-3.1: Certification standard for materials to ensure the alloy meets
required mechanical and chemical properties.
ASTM A240: Standard specification for chromium and chromium-nickel stainless
steel plate, sheet, and strip for pressure vessels and for general
applications.
ISO 9001: Quality management standard to ensure that the manufacturing
processes are consistent and meet customer requirements.
These standards provide the necessary guidelines to ensure that 445 stainless steel meets rigorous performance and safety criteria in industrial and
commercial applications.
Equivalent Grades (Comparable Alloys)
If 445 stainless steel is not available or suitable for your
application, there are several equivalent alloys with similar
properties. Some of the most commonly used alternatives include:
| Alloy Grade | Equivalent Standard | Properties |
|---|
| 430 Stainless Steel | UNS S43000 (ASTM A240) | Similar corrosion resistance but lower temperature performance |
| 409 Stainless Steel | UNS S40900 (ASTM A240) | Lower cost but reduced corrosion and oxidation resistance compared
to 445 |
| 441 Stainless Steel | UNS S44100 (ASTM A240) | Similar performance but with slightly improved weldability |
| 304 Stainless Steel | UNS S30400 (ASTM A240) | Higher nickel content, offers superior formability and corrosion
resistance but at a higher cost |
While these alloys have similar mechanical properties, each grade
has its own unique features that may make it more suitable for
specific applications. 445 stainless steel stands out due to its exceptional resistance to high-temperature
oxidation and corrosion in aggressive environments.
