nickel alloy 31 plate chemical Composition

Nickel (Ni): 30.0%-32.0%, Chromium (Cr): 26.0%-28.0%, Molybdenum (Mo): 6.0%-7.0%, Nitrogen (N): 0.15%-0.25%, Iron (Fe): Balance, Carbon (C): ≤0.03%, Manganese (Mn): ≤2.0%, Silicon (Si): ≤0.5%, Phosphorus (P): ≤0.03%, Sulfur (S): ≤0.01%.

uns n08031 sheet Corrosion Resistance

Alloy 31 Sheet has resistance in various media such as neutral salt spray, seawater, hydrochloric acid, sulfuric acid, and phosphoric acid. Especially in harsh environments containing chloride ions, its resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking is outstanding. Furthermore, this sheet can operate stably in mixed environments of oxidizing media (such as nitric acid) and reducing media (such as sulfurous acid), making it suitable for complex corrosive conditions.

alloy 31 sheet Mechanical Properties

At room temperature, the mechanical properties of Alloy 31 Sheet are as follows: Tensile strength ≥650MPa, Yield strength ≥280MPa, Elongation ≥40%, Hardness (HB) ≤220.

alloy n08031 plate Processing Performance

Alloy 31 Sheet can be subjected to conventional mechanical processing operations such as shearing, stamping, bending, and drilling. Appropriate tools and processing parameters should be selected during processing to avoid increased processing difficulty due to the material's high hardness and toughness. This sheet material possesses excellent welding properties and can be welded using conventional methods such as TIG welding and arc welding. After welding, it maintains good mechanical properties and corrosion resistance without requiring complex heat treatment.

nickel aloy 31 sheet High-Temperature Resistance

In high-temperature environments of ≤600℃, Alloy 31 Sheet maintains stable mechanical properties and corrosion resistance, without significant oxidation or performance degradation. Above 600℃, the material's strength gradually decreases, but it can still be used for short periods under certain operating conditions.
