UNS N08020 Stainless Steel Round Bar Alloy 20 Stainless Steel Rod for Harsh Conditions
UNS N08020, also known as Alloy 20, is a highly versatile stainless steel that combines excellent corrosion resistance, particularly in sulfuric acid and other aggressive environments, with good strength and weldability. This alloy is often used in industries requiring resistance to severe corrosive environments, such as chemical processing, pharmaceuticals, and power generation.
The chemical composition of UNS N08020 is designed to offer optimal corrosion resistance, particularly in the presence of sulfuric acid. Below is the typical composition of Alloy 20:
| Element | Percentage |
|---|---|
| Iron (Fe) | Balance |
| Nickel (Ni) | 32-38% |
| Chromium (Cr) | 19-21% |
| Molybdenum (Mo) | 2.0-3.0% |
| Copper (Cu) | 3.0-4.5% |
| Manganese (Mn) | 1.0% Max |
| Silicon (Si) | 1.0% Max |
| Carbon (C) | 0.07% Max |
| Sulfur (S) | 0.020% Max |
| Phosphorus (P) | 0.045% Max |
UNS N08020 (Alloy 20) offers a strong combination of strength, toughness, and durability, even in harsh environments. Here are the key mechanical properties:
| Property | Value |
|---|---|
| Tensile Strength | 75 ksi (515 MPa) |
| Yield Strength | 30 ksi (205 MPa) |
| Elongation | 35% |
| Hardness | 170 HB (Brinell) |
| Modulus of Elasticity | 28 x 10³ ksi (193 GPa) |
| Thermal Expansion | 15.7 x 10⁻⁶/°C (8.7 x 10⁻⁶/°F) |
UNS N08020 complies with various international standards that ensure its high quality and performance in demanding applications. These include:
ASTM B463: Standard Specification for Nickel-Chromium-Molybdenum Alloy (Alloy 20) Seamless and Welded Pipe and Tube
ASTM B564: Standard Specification for Nickel-Chromium-Molybdenum Alloy (Alloy 20) Forged or Rolled Pipe Flanges, Forged Fittings, and Valves and Parts
ASTM A312: Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes
DIN 17742: Stainless Steel Seamless Pipe
Alloy 20 (UNS N08020) is ideal for applications in highly corrosive environments, particularly those involving sulfuric acid, phosphoric acid, and other aggressive chemicals. Some of its common applications include:
Chemical Processing Equipment: Tanks, reactors, pipes, valves, heat exchangers
Pharmaceutical Industry: Equipment exposed to aggressive chemicals
Power Generation: Corrosion-resistant components in harsh environments
Food and Beverage Processing: Equipment resistant to corrosion from acidic products
Oil & Gas: Components for offshore drilling rigs and other harsh environments
