Arch City Steel & Alloy, Inc. provides specialized industrial steel distribution along with processing services across North America. The company focuses on stainless steel tubing systems along with nickel alloys and chrome moly materials. Engineers and procurement teams depend on the company for technical expertise in material selection and compliance standards.The company stocks 2205 duplex stainless steel pipe in accordance with ASTM A790 specifications for demanding industrial environments. This material contains 22 percent chromium, along with 3 percent molybdenum and 5 percent nickel in its chemical composition. The dual microstructure of austenite and ferrite phases delivers yield strength exceeding 65 ksi and tensile strength above 95 ksi. The 2205 grade demonstrates resistance to chloride stress corrosion cracking in temperatures reaching 302 degrees Fahrenheit. Pitting resistance equivalent number values exceed 35 for this duplex material. Marine environments, along with offshore oil platforms, create conditions where chloride ions concentrate through evaporation mechanisms.
"Engineers selecting materials for sour gas service need duplex grades meeting NACE MR0175 requirements for hydrogen sulfide environments," a company spokesperson stated. "The 2205 pipe performs well where austenitic materials fail prematurely due to chloride attack and stress corrosion mechanisms." The spokesperson explained that fabricators can weld this grade using ER2209 filler metal without requiring preheat or postweld heat treatment. "Procurement teams should verify mill test reports confirm proper ferrite content between 40 and 50 percent," the spokesperson noted.
Arch City Steel & Alloy, Inc. maintains inventory in seamless along welded configurations for immediate delivery to project sites. The stainless steel sheet supplier provides material certifications traceable to heat numbers for quality assurance documentation. Pipe sizes range from one-half inch through 12 inches in nominal bore dimensions. Schedule ratings include 10S through XXS to meet various pressure requirements in piping systems. Flue gas desulfurization systems in power plants require corrosion-resistant materials for acidic condensate handling.
Material selection for chloride service demands an understanding of local electrochemical cell formation within crevices, along with pit sites. The 2205 duplex pipe addresses these failure modes through its balanced microstructure and alloying additions. Projects specifying this material gain extended service life along with reduced maintenance costs in aggressive environments.
