Wear Resistant Alloy 20# Pipe HRB 60 - 80 Medium Carbon Steel With Good Weldability

20# Alloy is a medium-carbon steel primarily used for structural and mechanical applications where a good balance of strength, toughness, and wear resistance is required. This steel grade is known for its reliability in various industrial contexts due to its favorable combination of mechanical properties and ease of processing.

• Carbon (C): 0.17-0.23% - Provides a good balance of strength and hardness while maintaining reasonable ductility and machinability.
• Manganese (Mn): 0.35-0.65% - Improves tensile strength and hardness, and contributes to toughness and wear resistance.
• Silicon (Si): ≤0.35% - Aids in deoxidization during steelmaking, producing cleaner steel with smoother surface finish.
• Phosphorus (P): ≤0.035% - Low content helps avoid brittleness and ensures toughness and ductility.
• Sulfur (S): ≤0.035% - Minimizes inclusions for better machinability and overall strength.

• Tensile Strength: 370-530 MPa - Strong resistance to pulling forces for structural and mechanical uses.
• Yield Strength: ≥245 MPa - Withstands significant stress without permanent deformation.
• Elongation: ≥25% - Good ductility for fabrication and shaping.
• Density: 7.85 g/cm³ - Typical for medium-carbon steels, balancing strength with weight.
• Hardness: HB 150-200 - Provides good wear resistance while retaining flexibility and machinability.

• Construction: Structural components like beams, columns, and frames requiring moderate strength and good weldability.
• Mechanical Parts: Shafts, gears, and axles where durability and wear resistance are needed.
• Automotive Industry: Engine parts and transmission components requiring strength and formability.
• Metal Fabrication: Plates, rods, and tubes needing machining or forming.
