13CrMo4-5 Seamless Steel Tubes

High-strength chrome-moly seamless steel tubes manufactured to meet the needs of welded pressure equipment and elevated-temperature service. 13CrMo4-5 (EN grade) is a chromium-molybdenum alloy designed for welded boilers, pressure vessels and piping that operate at raised temperatures.

Key benefits

• Engineered for elevated-temperature strength and creep resistance compared with plain carbon steels
• Good weldability for fabrication of pressure vessels and boiler components
• Improved resistance to corrosive and “sour” environments common in oil, gas and petrochemical service
• Supplied as seamless tubes for superior integrity under pressure

Standards & compliance

• Grade: 13CrMo4-5 (EN specification)
• Manufactured and supplied in accordance with EN 10028-2 and EN 10216-2 technical delivery requirements (material testing, dimensional tolerances and inspection as specified by the standards)

Chemical composition (elements commonly present)

C, Si, Mn, P, S, Cr, Mo, N, Cu

Typical applications

• Welded pressure vessels and boilers
• High-temperature piping systems
• Oil & gas production and processing equipment
• Petrochemical plants and refineries

Commercial details
