Description

ASME SA213 T11 Seamless Alloy Tube 1.25Cr-0.5Mo Chrome Moly for Boiler Superheater Power Plant

ASME SA213 T11 corresponds to ASTM A213 T11. It is a low-alloy chromium-molybdenum steel seamless pipe, belonging to the category of ferritic heat-resistant steel. This material is manufactured according to ASME SA213 / ASTM A213 standards and is specifically designed for high-temperature pressure equipment such as boilers, superheaters, and heat exchangers.
SA213 T11 is suitable for medium- and high-pressure boilers and high-temperature pipelines in petrochemical industries with metal operating temperatures ≤ 550°C. Through the alloying design of chromium and molybdenum, it exhibits excellent heat resistance, oxidation resistance, and good weldability below 550°C.

Chemical Composition
Element Content Range (%) Metallurgical Function
C (Carbon) 0.05 – 0.15 Ensures high-temperature strength and creep limit; upper limit controlled to maintain weldability
Si (Silicon) 0.50 – 1.00 Deoxidation; improves high-temperature oxidation resistance
Mn (Manganese) 0.30 – 0.60 Strengthens matrix; improves hot workability
P (Phosphorus) ≤ 0.025 Strictly controlled to minimize embrittlement
S (Sulfur) ≤ 0.025 Reduces hot cracking risk
Cr (Chromium) 1.00 – 1.50 Forms Cr₂O₃ protective scale for oxidation resistance up to 550°C; synergizes with Mo to enhance hot strength
Mo (Molybdenum) 0.44 – 0.65 Solid-solution strengthening; inhibits temper embrittlement; significantly improves creep resistance

Mechanical Properties
Parameter Standard Requirement (Min.) Typical Value
Tensile Strength (Rm) ≥ 415 MPa 460 – 580 MPa
Yield Strength (Rp0.2) ≥ 205 MPa 275 – 360 MPa
Elongation (50mm gage length) ≥ 30% 35% – 40%
Hardness ≤ 163 HBW / ≤ 85 HRB 140 – 160 HBW
High-Temperature Yield Strength (550°C) — Approx. 205 MPa

Physical Properties (Reference Values)
Parameter Value Unit
Density ~7.85 g/cm³
Elastic Modulus (20°C) ~210 GPa
Thermal Conductivity ~42 W/(m·K)
Coefficient of Linear Expansion (20–400°C) ~12.5 ×10⁻⁶/°C

Application

  • Power Industry: Superheaters, reheaters, water-cooled walls, and other heating surface tube systems in power plant boilers (including supercritical and subcritical units)
  • Petrochemical Industry: High-temperature and high-pressure piping systems and process pipelines
  • Boiler Manufacturing: Water-cooled wall tubes, economizer tubes, and steam pipes
  • Heat Exchangers: High-temperature heat exchanger tube bundles
