WC6 steel is a low-alloy steel used primarily in the manufacturing of valves and fittings in the oil, gas, and petrochemical industries. It is a type of chrome-molybdenum steel that contains approximately 1% chromium and 0.5% molybdenum. The alloying elements in WC6 steel provide it with excellent high-temperature properties, high strength, and corrosion resistance.
WC6 steel is known as a "Grade 11" material and can be heat-treated to achieve high hardness and strength. It can be used in high-temperature service applications up to 375°C (700°F).
The chemical composition of WC6 steel typically includes carbon (0.15%-0.25%), manganese (0.30%-0.60%), phosphorus (max 0.035%), sulfur (max 0.040%), silicon (0.50% max), chromium (1.00%-1.50%), and molybdenum (0.44%-0.65%).
WC6 steel is often used for the manufacturing of valves, flanges, and fittings, where high strength, corrosion resistance, and resistance to high-temperature environments are essential. It is also used in the production of pumps, compressors, and other high-pressure pipeline equipment that is commonly seen in refineries and chemical plants.
Overall, WC6 steel is a valuable material for high-temperature and high-pressure applications where strength and corrosion resistance are paramount. It is widely used in the oil, gas, and petrochemical industries and offers excellent durability and reliability in harsh environments.
