P36 High Nickel Austenitic Steel Seamless Pipes for Nuclear Power Station Applications

Premium Quality by FUSHUN STEEL TUBE – Leading Manufacturer

P36 Steel Grade Introduction and Applications

FUSHUN STEEL TUBE specializes in manufacturing premium P36 high nickel austenitic steel seamless pipes specifically designed for nuclear power station applications. P36 steel represents an advanced austenitic stainless steel grade with high nickel content that delivers exceptional performance in corrosive and high-temperature environments typical of nuclear power generation facilities.

As a leading manufacturer in the steel tube industry, FUSHUN STEEL TUBE produces P36 pipes that comply with ASME SA335 standards and are equivalent to WB36CN1 specification, making them ideal for carbon and alloy products in nuclear station island and conventional island applications. Our P36 seamless pipes are engineered to provide excellent corrosion resistance, superior mechanical properties, and outstanding performance in nuclear reactor environments.

The P36 grade offers exceptional resistance to stress corrosion cracking, excellent weldability, and superior high-temperature strength retention, making it the preferred choice for critical nuclear power station components where corrosion resistance and reliability are paramount.

Primary Applications:

  • Nuclear reactor primary coolant system piping
  • Steam generator tubes and heat exchanger applications
  • Nuclear fuel handling systems
  • Reactor pressure vessel internal components
  • Primary and secondary loop piping systems
  • Nuclear waste processing equipment
  • High-temperature steam lines in nuclear facilities

P36 Chemical Composition

FUSHUN STEEL TUBE’s P36 seamless pipes are manufactured with precise chemical composition control to ensure optimal performance in nuclear applications. The P36 austenitic steel composition meets ASME SA335 specifications with high nickel content for superior corrosion resistance:

Element Composition % Purpose
Carbon (C) 0.08 max Strength and carbide formation
Manganese (Mn) 2.00 max Austenite stabilizer
Phosphorus (P) 0.045 max Controlled impurity
Sulfur (S) 0.030 max Controlled impurity
Silicon (Si) 0.75 max Deoxidization and strength
Chromium (Cr) 18.0 – 20.0 Corrosion resistance
Nickel (Ni) 32.0 – 37.0 Austenite stability & corrosion resistance
Molybdenum (Mo) 0.5 max Enhanced corrosion resistance
Titanium (Ti) 0.15 – 0.60 Carbide stabilization

The high nickel content (32.0-37.0%) combined with chromium (18.0-20.0%) in P36 steel provides exceptional corrosion resistance and austenitic stability essential for nuclear power station applications.
