Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service. Alloy Steel Seamless Pipes (ASME SA335 Grade P5) offered by us are made available in ASME SA335 as well as P1, P5, P9, P11, P12, P91 grades.ASTM A335 Alloy Steel Pipes (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy Steel Pipes for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding.  Sometimes referred to as “P Grade”, chome moly pipe is popular in P-Grades P5, P9, P11, P22, and P91.  The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants,  Grades P5 and P9 are commonly used  in refineries.

A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability.  Moly increases the resistance to softening, restrains grain growth and makes Alloy Steel Pipe less susceptible to embrittlement.  Moly is the most effective single additive that increases high temperature creep strength.  It also enhances the corrosion resistance of steel, and inhibits pitting. Alloy Steel Pipes is the essential constituent of stainless steel.  Any steel with 12% or more Chrome is considered stainless. Alloy Steel Pipes is virtually irreplaceable in resisting oxidation at elevated temperatures.Alloy Steel Pipes raises the tensile, yield, and hardness at room temperatures.  The composition chrome moly alloy steel pipes make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.  We are specialized in offering precision engineered Alloy Steel Pipes, which are used in various engineering applications and can be availed in various grades like ASTM A-335, A-387 GR. P1, P5, P9, P11, P12, P22, P91 etc. A-515/516 GR. 60/70, & IS 2062, IS 2002 etc

What are the benefits and applications of Alloy Steel Pipes?
The main applications of alloy steel pipes is power station, nuclear power plant, high pressure boiler, high temperature superheater and re-heater coil etc. of high temperature pipeline and equipments.
The advantages of alloy steel pipes: 100% recycled, it is suitable for the national strategy of environmental protection, energy-saving and resource-saving. Therefore, the national policy encourages the expansion of the high pressure alloy steel pipe applications.
At present, the proportion of the total alloy steel tube is half of the developed countries. The applications of alloy steel pipe provide a broad space for the industry development. According to the research of the China association of special steel alloy pipe expert group, our country’s high pressure alloy steel pipe material demand grows by an average of up to 10-12%.
How do I choose which alloy steel to use? Selecting the right alloy  for a specific application is vitally important in order to achieve a sustainable solution, while cost aspects must also be taken into consideration. There are several stages when material selection needs to be made:
New applications and equipmentNew processes and process changesExchange of material due to poor performanceExchange of existing material to minimize costTo make the right material selection it is important to get a full picture of the service conditions the steel will face. The first aspects to consider could be material related, for example:
Corrosion resistanceMechanical strengthFabric abilityPhysical propertiesSurface
