Mechanical properties of A335 P9 pipes are that they have a minimum Yield Strength of 205 Mpa, they have a minimum Tensile Strength of 415 Mpa and they have a minimum elongation percentage of 30/20 L/T. Having a UNS Designation of S50400, A335 P9 material composition is that of Silicon(max.) 0.50, Molybdenum 0.45 - 0.65, Carbon(max.) 0.15, Chromium 4.00 - 6.00 and Manganese 0.30 - 0.60. A335 P9 surface treatment can be done by shot blasting, phosphating, varnishing, oil-dip and passivation. Testing and inspection of A335 P9 pipes are done by flattening test, surface and dimension test, chemical composition inspection, mechanical properties test, hardness test, bending test, etc.
A335 P9 pipe is just excellent when it comes to using them for flanging or bending and various other similar uses like fusion welding, etc. Important to note is that A335 P9 pipe has been built for high-temperature service. Alloy Steel ASTM A335 P9 pipe uses are many and they are used all over the world in many different kinds of industries such as electric power, chemical, petroleum, boiler, oil, and gas, etc. The reason why A335 P9 pipe has such big demand in various applications is that's why they offer excellent resistance to corrosion, plus they are very resistant to high temperatures, as well as low temperatures.
A335 P9 pipe Thermal Conductivity will vary from a range between 15.1 at 1500 °F to 21 at 800 °F to 23.5 at 70 °F. For example, the thermal conductivity could be 6.4 at 70 °F, 6.5 at 100, 7.3 at 500 and even at 7.3 it could still be 550. At 7.4 it can be at 600, at 7.9 it could be at 850 or it can even be at 900. At 8.1 it can be at 1000 or even at 1050.

ASTM A335 P9 Welded Pipe
Alloy Steel P9 Seamless Pipe and Alloy Steel P9 Pipe are suitable for high-temperature application such as bending, flanging (vanstoning), and similar forming operations, and for fusion welding in the power industry and petrochemical plants. ASME SA 335 Alloy Steel P9 Seamless Pipe is also known as ASTM A335 P9 chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). ASTM A335 gr P9 Pipe (Chrome-Moly, ASME S/A335) is a seamless ferritic Alloy-Steel Pipe for high-temperature service. Molybdenum maintains the strength of Alloy Steel P9 Square Pipe as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly is the most effective single additive that enhances high temperature creep strength of ASTM A335 Grade P9 Alloy Steel Seamless Pipe.

Carbon steel is a large category of steel that encompasses many varying chemical compositions. Each type of carbon steel requires different considerations when welding. For example if you choose Low carbon steel to weld which is typically the most readily welded steel in a room temperature environment. These low carbon steel suitable for welding include C1018, A36, A1011, C1008, and A500. Medium carbon steel such as C1045 typically requires preheat and post-heat treatment to avoid weld cracking. High carbon steel is even more prone to weld cracking than the other two groups of carbon steel. Welding high carbon steel will most likely require very thorough preheating and post-heating processes to avoid this. It could also require special welding filler metals.
ASTM A335 P9 Pipe welding is used extensively for pipe welding, aerospace, aviation, biomedical implants, fabrication of race cars, choppers, etc.
Difference Between Low-Alloy Steel & High-Alloy Steel
Alloy Steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels.
High-Alloy Steel
High-alloy steels are defined by a high percentage of alloying elements. Stainless steel is high-alloy steel which contains at least 12 percent chromium. Stainless steel is devided into three basic types: martensitic, ferritic, and austenitic. Martensitic steels contain the least amount of chromium, and known for high hardenability, and are mainly used for cutlery. Ferritic steels contains 12 to 27 percent nickel chromium alloy and are suitable to use in automobiles and industrial equipment. Austenitic steels contain high levels of nickel, carbon, manganese, or nitrogen and usually have the highest corrosion resistance. Austenitic steels are mainly used to store corrosive liquids and mining, chemical, or pharmacy equipment.
Low-Alloy Steel
Among alloy steels, when Ni, Cr, Mo, and other alloy elements content consist of less than 10.5% are known as low alloy steels. Low-alloy steels have a much lower percentage of alloying elements, usually 1 to 5 percent. These steels have very different strengths and uses depending on the chosen alloy. High-strength low-alloy (HSLA) steels, or microalloyed steels, are designed to provide better mechanical properties and/or greater resistance to atmospheric corrosion than conventional carbonsteels in the normal sense.
Alloy steel can further classify as
- Low alloy steels: in which sum of total Alloying elements is < 5%
- High alloy steels: in which sum of total Alloying elements is > 5%
Uses of Alloy Steel
Use of Alloy Steel is mainly in automobile industry and machinery parts. Alloy steel can be used in process area where carbon steel has limitation, below are few application of alloy steel:
- High-temperature services such as Heater tubes, Alloy Steel Boiler Tubes
- Low-temperature services such as Cryogenic application
- Very High presser service such as Steam Header
- Used in construction of aircrafts and heavy vehicles for crank shafts, camshafts and propellor shafts, etc.
- General Engg and mould basis.
