Complete Range of Chemical And Mechanical Properties of Alloy Steel Pipes
What is an Alloy Steel?
Alloy steels contain alloying elements (e.g. manganese, silicon, nickel, titanium, copper, chromium, and aluminum) in varying proportions in order to manipulate the steel’s properties, such as its hardenability, corrosion resistance, strength, formability, weldability or ductility. The difference is somewhat uniform, but to make it distinguishable, all steel alloyed with higher than 8% of its weight of elements other than carbon and alloy is considered high-alloy steel. Alloyed steels are harder, more durable and more resistant to corrosion. Alloy steels with carbon levels of medium to elevated rates are difficult to weld. However, if the carbon levels are reduced to 1% to 3%, such alloy metals can achieve greater formability and weldability, thus, improved strength.
Applications of Alloy Steel
Alloy steel seamless pipes are widely used for low and medium pressure fluid transportation pipeline, casing tube, boiler pipe, petroleum and natural gas industry, chemistry industry, power generation industry, transformers, agriculture, bearings, general engineering, automotive, hydraulics, railway, mining, construction, aerospace, medical, defense and electric motors. Alloy steels grade P91 is mainly used for power industry. For welded construction, the ASME Boiler and Pressure Vessel Code limits the carbon content to less than 0.35%. Alloy steel is ideally suited for applications that require higher strength, improved toughness or better wear resistance than standard carbon steel grades. Alloy Steels are used in boiler construction because they are inexpensive, readily available, easily formed and welded to the desired shape and, within the broad limits, are oxidation- and corrosion-resistant enough to provide satisfactory service for many years to many industries. Alloy Steel is used across a range of highly demanding applications within the aerospace and power (nuclear) industries. Alloy Steel is also found in applications where its response to magnetism is important, in transformers and electric motors for example.

Heat Treatment of Alloy Steel Pipes
- Pipe may be either hot finished or cold drawn with the finishing treatment as required.
- Grade P2 and P12 — the steel shall be made by coarse grain melting practice. Specific limits, if any, on grain size or deoxidation practice shall be a matter of agreement between the manufacturer and purchaser.
- All pipes of grades except P5c, P23, P91, P92, P122, and P911 shall be reheated and furnished in the full-annealed, isothermal annealed, or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature for Grades P5, P5b, P9, P21, and P22 shall be 1250°F [675°C], the minimum tempering temperature for Grades P1, P2, P11, P12, and P15 shall be 1200°F [650°C].
- NOTE – It is recommended that the temperature for tempering should be at least 100°F [50°C] above the intended service temperature; consequently, the purchaser should advise the manufacturer if the service temperature is to be over 1100°F [600°C].
- Pipe of Grades P1, P2, and P12, either hot finished or cold drawn, may be given a final heat treatment at 1200°F [650°C] to 1300°F [705°C] instead of heat treatments as specified above.
- All pipe of Grades P5c shall be given a final heat treatment in the range from 1325°F [715°C] to 1375°F [745°C].
- NOTE – Certain of the ferritic steels covered by this specification will harden if cooled rapidly from above their critical temperature. Some will air harden, that is, become hardened to an undesirable degree when cooled in air from high temperatures. Therefore, operations involving heating such steels above their critical temperatures, such as welding, flanging and hot bending, should be followed by suitable heat treatment.
- Grades P92 and P911 shall be normalized at 1900°F [1040°C] minimum and tempered at 1350°F [730°C] minimum as a final heat treatment.
- Grade P122 shall be normalized at 1900°F [1040°C] minimum, and tempered at 1350°F [730°C] minimum as a final heat treatment.
- Grade P23 shall be normalized at 1900°F [1040°C] minimum with air cooling or accelerated cooling and tempered at 1350°F [730°C] minimum as a final heat treatment.
- Except when Supplementary Requirement S7 is specified by the purchaser, Grade P91 shall be normalized at 1900°F [1040°C] minimum, and tempered at 1350°F [730°C] minimum as a final heat treatment. Alternatively, liquid quenching and tempering is allowed for thicknesses above 3 inch when mutually agreed upon between the manufacturer and the purchaser. In this case the pipe shall be quenched from 1900°F [1040°C] minimum and tempered at 1350°F [730°C] minimum as final heat treatment.
Solution Treatment For Alloy-based Steel Pipe
Heating an alloy to a proper temperature, preserve it at this temperature long enough to cause or more constituents to change into a solid solution, then cooling it at rapid rate to hold these constituents in solution. There are various of cast and wrought nickel-based alloys that can achieve different required performances through solution treatment or by precipitation age hardening. Characteristics as room temperature and elevated temperature mechanical strength, corrosion resistance and oxidation resistance will be significantly enhanced by this heat treatment. Many nickel-based alloys develop their desired properties solely through the solution treatment, like Hastelloy and nickel alloy steel pipe. During solution treatment, the carbide and various alloying elements are dissolved uniformly in the austenite. Cooling rapidly will make carbon and alloy elements too late to precipitate, and obtain the heat treatment process of single austenite tissue. The solution treatment can uniform internal structure and chemical compostion. It can also restore the corrosion resistance for Hastelloy and nickel alloy steel pipe.
