Looking for ASTM A182 F22 Class 3, ASME SA-182 F22 Class 3 or 2.25Cr-1Mo alloy steel round bars?
WTE PowerSteel is a European supplier and stockholder of ASTM A182 F22 Class 3 chromium-molybdenum alloy steel for demanding high-temperature and high-pressure applications. We supply certified round bars with full material traceability, EN 10204 3.1 certification and fast worldwide delivery.
ASTM A182 F22 Class 3 is a 2.25Cr-1Mo low-alloy steel developed for pressure-containing components operating under elevated temperatures, high internal pressure and demanding mechanical loading.
Compared with F22 Class 1, F22 Class 3 is supplied with higher specified tensile and yield strength. This makes it particularly suitable for critical forged and machined components used in power generation, petrochemical processing, refineries, oil and gas production and high-pressure equipment.
We supply both full-length bars and precision cut-to-length pieces according to customer requirements.
ASTM A182 F22 Class 3 provides an excellent combination of high mechanical strength, elevated-temperature stability, pressure resistance, toughness and machinability.
The chromium and molybdenum additions improve hardenability, oxidation resistance and long-term mechanical performance under demanding operating conditions.
ASTM A182 F22 Class 3 is widely used for components exposed to high pressure, elevated temperatures and severe mechanical loading.
Typical applications include:
Our customers use ASTM A182 F22 Class 3 in:
We supply:
Available diameters, lengths and heat-treatment conditions upon request.
ASTM A182 F22 Class 3 material is supplied in accordance with:
ASTM A182 covers forged or rolled alloy-steel components intended primarily for high-temperature pressure systems, including flanges, forged fittings, valves and similar pressure-containing parts.
When round bars are supplied for the manufacture of finished ASTM A182 components, the required manufacturing route, heat treatment, mechanical testing, inspection and certification must be specified according to the applicable standard and customer requirements.
ASTM A182 F22 is a chromium-molybdenum low-alloy steel containing nominally:
The exact chemical composition must comply with the applicable edition of ASTM A182 or ASME SA-182 and must be confirmed by the material inspection certificate.
ASTM A182 F22 Class 3 is differentiated from lower-strength F22 classes by its increased specified mechanical properties.
Typical minimum room-temperature mechanical requirements for Class 3 include:
The applicable mechanical properties depend on the specification edition, product form, section thickness, heat treatment, testing orientation and customer-specific requirements.
All required values must be verified against the applicable ASTM or ASME standard and the individual material certificate.
ASTM A182 F22 Class 3 is supplied in an appropriate heat-treated condition to achieve the required combination of strength, toughness, hardness and high-temperature stability.
Depending on the dimensions, product form and manufacturing route, heat treatment may include:
Correct heat treatment is essential for obtaining the required Class 3 mechanical properties.
Material can be supplied with:
All additional testing and documentation requirements must be specified at the enquiry or order stage.
This material is also known as:
ASTM A182 F22 is frequently compared with European chromium-molybdenum grades such as:
However, ASTM A182 F22 Class 3 and EN 1.7380 / 10CrMo9-10 must not automatically be considered fully interchangeable.
The applicable product standard, chemical composition, mechanical properties, heat treatment, dimensions, manufacturing route and inspection requirements must be reviewed before any material substitution.
WTE PowerSteel specializes in supplying alloy steels, heat-resistant steels and special materials for demanding high-temperature and high-pressure applications.
Our advantages include:
Whether you require a single cut piece, a complete bar or material for serial production, our team will help you select the correct material condition, dimensions and inspection requirements.
ASTM A182 F22 Class 3 is a high-strength chromium-molybdenum low-alloy steel intended primarily for forged or rolled pressure-containing components used at elevated temperatures.
It contains approximately 2.25% chromium and 1% molybdenum and is commonly used for flanges, valves, fittings, wellhead equipment and other high-pressure components.
F22 identifies a chromium-molybdenum alloy-steel grade covered by ASTM A182 and ASME SA-182.
The letter “F” identifies a grade intended for forged products, while the grade number identifies the applicable alloy composition and specification requirements.
Class 3 identifies a higher-strength mechanical-property condition within ASTM A182 Grade F22.
F22 Class 3 requires higher specified tensile and yield strength than F22 Class 1. The alloy composition is based on the same 2.25Cr-1Mo steel family, but the required heat treatment and mechanical properties differ.
The principal difference is the required mechanical strength.
F22 Class 3 is heat treated to achieve higher tensile and yield properties than F22 Class 1. This makes Class 3 suitable for components requiring increased mechanical performance under high pressure or severe loading.
The required class must always be clearly stated in the purchase order and inspection certificate.
ASTM A182 F22 and EN 1.7380 / 10CrMo9-10 belong to a similar chromium-molybdenum alloy family and are often presented as comparable grades.
They are not necessarily direct or universally interchangeable equivalents. Their chemical limits, mechanical requirements, heat treatment, product standards and certification requirements must be compared for the specific application.
No. They are comparable 2.25Cr-1Mo alloy steels, but they are specified under different material and product standards.
ASTM A182 F22 Class 3 is primarily intended for forged pressure components, while 10CrMo9-10 may be supplied under different European product standards and with different mechanical-property requirements.
Yes. F22 is specifically intended for elevated-temperature service and is widely used in high-temperature pressure systems.
The actual permissible operating temperature depends on the component design, wall thickness, applied stress, applicable design code, heat treatment and required service life.
Yes. ASTM A182 F22 Class 3 is widely used for high-pressure flanges, valves, fittings, wellhead equipment and other pressure-containing components.
Suitability for a specific pressure and temperature must be evaluated according to the applicable component and design code.
Yes. F22 can be welded using qualified welding procedures.
Because it is a hardenable chromium-molybdenum alloy steel, controlled preheating, suitable filler material, controlled interpass temperature and post-weld heat treatment may be required.
Yes. ASTM A182 F22 Class 3 has good machinability when suitable cutting tools and machining conditions are used.
Sawing, turning, milling, drilling, boring and threading are commonly performed on this material.
Yes. WTE PowerSteel supplies selected dimensions of ASTM A182 F22 Class 3 round bars and cut-to-length pieces from European and international sources.
Please contact us for current stock availability, available diameters, lengths, heat-treatment conditions and certification details.
