What are ASTM A234 WP11 Alloy Buttweld Fittings?
ASTM A234 WP11 Alloy Buttweld Fittings are pipe fittings made from Alloy Steel WP11, a chromium-molybdenum alloy known for excellent strength, resistance to creep, and high-temperature durability. These fittings are commonly used for joining, redirecting, or terminating piping systems that transport steam, oil, gas, and other high-pressure fluids.
The “WP11” grade specifically refers to alloy steel with chromium (Cr) and molybdenum (Mo) content, making it highly resistant to oxidation and thermal fatigue. That’s why ASTM A234 WP11 Pipe Fittings are the preferred choice in power generation, refinery, chemical, and energy industries.
