While stainless steel itself is renowned for its corrosion resistance and mechanical properties, the selection of compatible metals for various applications is equally important. Here’s how the choice of metal impacts the overall performance and durability of stainless steel:
Corrosion resistance:
Stainless steel’s corrosion resistance is attributed to its chromium content, which forms a passive oxide layer on the surface. However, when incompatible metals are in contact with stainless steel, they can initiate galvanic corrosion or pitting, compromising its corrosion resistance. By selecting metals with similar corrosion resistance properties, the overall durability of stainless steel structures is enhanced.
Mechanical compatibility:
Stainless steel is often used in structural applications where strength and load-bearing capacity are crucial. When choosing metals for joint or connection points, mechanical compatibility is vital to ensure proper load transfer, structural integrity, and resistance against fatigue or stress corrosion cracking. Metals with similar mechanical properties or suitable reinforcing materials can enhance the overall performance and longevity of stainless steel structures.
Thermal expansion and contraction:
Stainless steel structures are subjected to temperature variations, leading to thermal expansion and contraction. The choice of metal must consider similar coefficients of thermal expansion to minimize differential movement and stress accumulation. Mismatched metals with significant differences in thermal expansion coefficients can cause material distortion, joint failure, or reduced overall durability.
Aesthetic considerations:
In architectural or decorative applications, the choice of metals can impact the aesthetic appeal and longevity of stainless steel components. Metals with compatible surface finishes or plating options can create a cohesive appearance and prevent unsightly corrosion or discoloration that may occur due to galvanic reactions.

Yield strength is the stress at which a material begins to deform permanently. SUS304 stainless steel generally exhibits a yield strength of about 205 MPa, while 316Ti stainless steel has a slightly higher yield strength of approximately 240 MPa. The higher yield strength of 316Ti contributes to its improved resistance against plastic deformation.
Hardness:
Hardness is a measure of a material’s resistance to indentation or scratching. Both SUS304 and 316Ti stainless steel grades exhibit excellent hardness properties. SUS304 typically has a hardness of around 88 on the Rockwell hardness scale (HRC), while 316Ti stainless steel offers a similar hardness range of approximately 87 HRC. These hardness values indicate the materials’ ability to resist wear and maintain their structural integrity.
Impact Strength:
Impact strength measures a material’s ability to absorb energy during sudden loading or impacts. While both SUS304 and 316Ti stainless steel grades have good impact resistance, 316Ti often shows slightly better performance due to its higher tensile and yield strength. This makes 316Ti stainless steel suitable for applications that require resistance against impact or dynamic loading.
Ductility:
Ductility refers to a material’s ability to deform plastically without fracturing. SUS304 stainless steel offers excellent ductility, allowing it to undergo extensive forming and fabrication processes. Similarly, 316Ti stainless steel also exhibits good ductility, making it suitable for applications that require complex shapes or bending.
It’s important to note that the mechanical properties of stainless steel can be further influenced by factors such as heat treatment, cold working, and alloying elements. Stainless steel material suppliers can provide detailed information on the mechanical properties of different grades and assist in selecting the most suitable grade for specific applications.
