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
