Product information

Grade: SUS405 
SUS405 stainless steel (ferritic stainless steel) has the following performance characteristics:
Corrosion resistance
It has good corrosion resistance at room temperature to oxidizing acids (such as nitric acid) and fresh water, but protective measures are required for strong acids, strong bases, and chloride environments. Its resistance to chloride stress corrosion is superior to that of other ferritic stainless steels. ‌
Mechanical properties
‌Basic mechanical data‌
Tensile strength ≥ 490 MPa, yield strength ≥ 345 MPa, elongation ≥ 24%, hardness ≤ 183 HB (annealed state). ‌
‌Properties after heat treatment‌
After quenching (950-1000°C oil cooling) and tempering (700-750°C rapid cooling), the tensile strength can reach ≥ 550 MPa. ‌
Processing properties
‌Processing characteristics‌
It has good cold and hot processing properties and can be processed by conventional methods such as stamping, bending, and cutting. ‌
‌Welding properties‌
It can be welded using conventional welding methods such as arc welding and gas shielded welding, but post-welding heat treatment is required to restore toughness. ‌ Applicable scenarios
Mainly used for manufacturing mechanical components that are resistant to corrosion by water vapor and sulfur-containing petroleum (such as turbine blades, bolts, nuts), as well as the inner linings of equipment in high-temperature oxidation environments.

Product parameter

Chemical composition

The chemical composition of SUS405 stainless steel is as follows (indicated by the main alloy elements and their content ranges):
‌Chromium (Cr): 11.5% - 15.5%
Provides the basic corrosion resistance, and the content range varies slightly in different standards.
‌Carbon (C): ≤ 0.08%
Low-carbon design to improve welding performance.
‌Aluminum (Al): 0.1% - 0.3%
Stabilizes the ferrite structure and reduces high-temperature brittleness.
‌Other elements:
Silicon (Si), Manganese (Mn): ≤ 1.00%
Phosphorus (P): ≤ 0.04%
Sulfur (S): ≤ 0.03% - 0.04%
Nickel (Ni): ≤ 0.60%
Note: Some standards (such as ASTM) may add a limit on molybdenum (Mo) content (≤ 0.50%)
