What Is Stainless Steel AISI 410? All You Must Know

Stainless steel (SS) is a well-known and versatile material used across various industries. It displays considerable durability, stability, and aesthetic appeal, making it a top choice for many manufacturers and designers. One particular type of stainless steel is AISI 410.

This steel is martensitic and commonly used in various industrial applications. It is a material popular for its strength, hardness, and resistance to wear and tear, making it suitable for environments with high temperatures and harsh conditions.

Understanding the characteristics and properties of AISI 410 material can help manufacturers and designers choose the right type of stainless steel for their products.

Chemical Properties of AISI 410 SS

The AISI 410 SS contains high amounts of chromium and carbon. This particular grade of stainless steel also contains manganese, phosphorous, silicon, sulfur, and iron. The most prominent characteristics of this steel, such as hardness, corrosion resistance, and durability, are a direct product of its chemical composition.

Chemical Composition

The chemical components of stainless steel AISI 410 alongside iron are as follows:

  • Carbon (C): 0.15%.
  • Chromium (Cr): 11.5 – 13.5%.
  • Manganese (Mn): 1%.
  • Phosphorus (P): 0.04%.
  • Sulfur (S): 0.03%.
  • Silicon (Si): 1%.

Let’s discuss the characteristics these elements impart to AISI 410.

  • Carbon provides strength to steel and improves its hardness.
  • Chromium is the main alloying element here, and it provides stability against corrosion and wear and tear.
  • Manganese makes it stronger and more ductile.
  • Phosphorus and sulfur are impurities that must be controlled to prevent brittleness.
  • Silicon helps in the deoxidization of the steel during the steelmaking process.

The chemical composition of this stainless steel can be adjusted by altering the levels of each element to obtain specific properties. For example, increasing the carbon content can increase the hardness and strength, but it may also reduce the flexibility and toughness of the steel.

Physical Properties of AISI 410 SS

Physical Properties of AISI 410 SS

The chemical composition discussed above gives this material its high density, strength, low thermal conductivity, and exceptional corrosion resistance. These properties make this material an ideal candidate for use in kitchen knives, screws, and valves. Here are the details.

1. Density

The density of this material is around 7.7 g/cm³ at room temperature, which is relatively high compared to other stainless steel grades.

In contrast, the density of austenitic stainless steel grades like AISI 304 and AISI 316 is around 7.9 g/cm³.

2. Thermal Conductivity

AISI 410’s thermal conductivity is lower than other metals, with a value of 25 W/mK around room temperature.

The low thermal conductivity of this substance makes it less suitable for applications where controlling heat transfer is a primary requirement. You can compare it to copper’s 400 W/mK, and aluminum’s 200 W/mK.

3. Electrical Resistivity

This stainless steel has a moderate electrical resistivity of about 5.7×10^-7 Ωm at room temperature. This is lower than copper and aluminum but higher than other stainless steel grades, such as AISI 304 and AISI 316 stainless steel.

For example, the electrical conductivity of AISI 304 is about 1.45×10^-6 Ωm, while that of AISI 316 is around 1.25×10^-6 Ωm.

4. Corrosion Resistance

Stainless steel AISI 410 is martensitic stainless steel with good stability against corrosive forces in mild environments. It has a higher corrosion resistance than other martensitic stainless steels, such as AISI 420 and AISI 431, but lower than austenitic stainless steels, such as AISI 304 and AISI 316.

Mechanical Properties of AISI 410 Stainless Steel

Compared to other stainless steel grades, such as austenitic stainless steels, AISI 410 has a lower corrosion resistance but higher hardness. Its reduced ductility and low elongation limit its use in applications with critical impact or stress resistance.

You can use AISI 410 if you require high hardness and wear resistance, such as in cutlery, surgical instruments, and industrial equipment parts. Let’s discuss its mechanical properties.

1. Hardness and Toughness

This grade of stainless steel is strong with good wear resistance. Its hardness is typically 40-50 HRC, higher than other stainless steel grades. For example, the hardness of AISI 304 and AISI 316 is typically in the range of 70-90 HRB, which is lower than that of AISI 410.

However, this hardness makes this steel less tough – brittle. SS AISI 410 is brittle and may crack or fracture under impact or stress, unlike more ductile stainless steel grades like AISI 304 and AISI 316.

2. Tensile Strength, Yield Strength, and Elongation

The tensile strength of this material is around 480 MPa, and its yield strength is about 275 MPa. AISI 410’s elongation is relatively low, typically around 20%. This is due to the steel’s high hardness and reduced ductility.

For comparison, the tensile strength of AISI 304 and AISI 316 is around 515-620 MPa, while their yield strength is around 205-415 MPa. The elongation of these materials is much higher, typically around 40-60%.
