Difference Between Duplex and Super Duplex Stainless Steel

Super duplex stainless steel and duplex stainless steel differ primarily in their alloy composition and corrosion resistance. Super duplex stainless steels typically contain about 25% chromium, compared to the 22% chromium content in duplex stainless steel grades. This increased chromium content enhances the pitting corrosion resistance, making super duplex materials suitable for more aggressive environments. […]

What Is Super Duplex Material & Definition

Super Duplex stainless steel, as the name suggests, combines the characteristics of two main alloy types: austenitic and ferritic stainless steels. The microstructure of duplex material typically comprises an equal 50/50 mix of these phases, offering a balance of strength and corrosion resistance. In metallurgy, stainless steel is an alloy containing at least 10.5% chromium, […]

Density of Steel – Mild and Carbon Density of Steel lb/in3

What is the Density of Steel? Steel has a density of approximately 7.85 g/cm³ or 7850 kg/m³, equivalent to about 490 pounds per cubic foot. Its high density contributes to its strength and durability, making it a preferred choice for construction and industrial applications. When buying steel, understanding details like dimensions, weight, and density is […]

What is Alloy Steel | Types, Properties, Applications

What Is Alloy Steel? Alloy steel is created by mixing iron with other elements like silicon, chromium, molybdenum, boron, vanadium, nickel, and aluminum. These alloying elements enhance its strength, toughness, hardness, and resistance to wear and corrosion. Key Alloying Elements and Their Benefits Manganese: Reduces brittleness and improves workability, especially when combined with sulfur and […]
