The Duplex 2205 Round Bar is a remarkable ferritic-austenitic stainless steel bar, embodying the perfect balance of 22% chromium, 3% molybdenum, and 5-6% nickel. Renowned as the most widely utilized duplex stainless steel grade, it boasts an impressive yield strength that doubles that of conventional austenitic grades. Its exceptional performance extends to remarkable fatigue strength and unparalleled resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion under severe conditions.
Manufacturers recommend a maximum hot forming temperature range of 2010 to 2100°F (1100 to 1150°C). For non-compact shapes, the edges may cool more rapidly, raising the risk of cracking in these cooler regions.
Duplex 2205 boasts exceptional formability across various fabrication processes. While its high strength can present challenges, even robust equipment must account for the increased spring-back due to the grade's superior strength. Proper adjustments ensure optimal performance and precision.
Machining Duplex stainless steel bar 2205 is somewhat more challenging than working with 300 series austenitic stainless steel. It demands higher cutting forces, leading to accelerated tool wear. Consider these expert guidelines for best results: A) Employ a powerful, rigid machine equipped with a robust tool and secure workpiece mount; B) Minimize vibration by keeping tool extensions short; C) Maintain a sharp carbide edge by limiting the tool nose radius to necessary lengths, ensuring strength and precision; D) Strategically sequence machining steps to ensure each cut remains below any work-hardened layer from prior operations.
