ASTM A217 WC9 Valves — Frequently Asked Questions
ASTM A217 WC9 is a Cast Low Alloy Steel (2.25% Cr, 1.0% Mo) used for critical high-pressure, high-temperature service like ultra-supercritical steam and hydrogen. It is suitable for temperatures from -29°C (-20°F) up to 600°C (1112°F).
The 'WC9' in ASTM A217 WC9 is a low alloy steel casting grade containing 2.0% to 2.5% Chromium and 0.9% to 1.1% Molybdenum. This composition offers superior resistance to creep rupture and hydrogen attack at extreme temperatures, making it a key material for pressure-retaining valves.
WC9 valves are predominantly used in the Power Generation sector (Ultra-Supercritical Steam Lines), Oil & Gas Refineries (Hydrotreating, Hydrocracking units for hydrogen service), and any process requiring high thermal stability and creep strength above 550°C.
Dipti Metal Industries is a leading manufacturer and stockist of ASTM A217 WC9 Gate Valves, WC9 Globe Valves, and WC9 Check Valves, often utilizing the Pressure Seal Bonnet (PSB) design for high-pressure applications up to Class 2500.
