ASTM A335 P92 Pipe Suppliers, SA335 P92, P92 Pipe stockist, ASTM A335 Gr P92 Pipe, ASTM A335 P92 Alloy Steel Pipe Manufacturer in India
A335 P92 pipes are primarily used in many industries that call for high-temperature service. ASME B36.10M pipes are obtainable in various thicknesses, sizes, grades and specifications and they can also be tailor-made to meet specifications of clients. ASTM A335 P92 ASME B36.10M range of pipes can be obtained right here at our website. These pipes are used in many different industries such as heavy engineering, shipbuilding, oil & gas, power plants, etc. These ranges of pipes have the best features to offer such as anti-corrosiveness, durability, precision design, lightweight, dimensional accuracy, longer service life and so much more.
The UNS Designation of A335 P92 is K92460. Because of their material composition, A335 P92 pipes are ideal for fusion welding, flanging, bending and similar types of forming operations. The material of A335 P92 pipes has to conform to hardness requirements, tensile property and composition. A335 P92 material composition is that of Chromium 8.50–9.50, Manganese 0.30–0.60, Ni (max) 0.4, B 0.001-0.006, Carbon 0.07–0.13, Silicon 0.50 max, Molybdenum 0.30–0.60, Cb 0.04-0.09, V 0.15-0.25, Phosphorus (max) 0.02, W 1.5-2.00, N 0.03-0.07, Ti (max) 0.01, Al (max) 0.02, Sulfur(max) 0.01 and Zr (max) 0.01.
A335 P92 pipe allowable stress is very high as these pipes are high-pressure seamless boiler pipes. To confirm their stress worthiness, A335 P92 pipes undergo various kinds of mechanical tests such as bend or hardness test, flattening test, transverse or longitudinal tension test. The length of each and every A335 P92 pipe is also subjected to hydrostatic testing. Plus, A335 P92 pipes also undergo other tests such as Mechanical Properties Test, Surface and Dimension Test, Chemical Composition Inspection and No-destructive Test, so as to ensure they meet the required stress standards.
In ASTM A335 P92 Pipe Molybdenum (MO) increases strength, hardenability, hardness, and toughness, as well as creep resistance and strength at elevated temperatures. SA335 P92 is categorized by alloy or alloy percentage. It improves AISI P92 ERW Pipes & ASTM A335 Alloy Steel P92 EFW Pipe machinability and resistance to corrosion and it intensifies the effects of other alloying elements. In hot-work steels and high-speed steels, it increases red-hardness properties of ASTM A335 Grade P92 Pipes.

ASTM A335 P92 Seamless Pipe
Alloy Steel P92 Pipe and P92 Seamless 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. ASTM A335 gr P92 Pipe (Chorme-Moly ASME S/A335) is a seamless ferritic Alloy-Steel Pipe for high temperature service. ASME SA 335 Alloy Steel P92 Seamless Pipe is also known as ASTM A335 P92 chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum Maintains the strength of P92 Square Pipe as well as the elastic limit, impact qualities, resistance to wear, and hardenability. Moly is the most effective single additive that enhances high temperature creep strength of ASTM A335 Grade P92 Alloy Steel Seamless Pipe.
Long Lengths High-Pressure P92 Boiler Pipe & ASTM A335 Alloy Steel P92 Seamless Pipe are available in hot rolled condition up to 22.5m. Seamless ferritic alloy steel P92 pipe can be supplied to meet special surface requirements and/or close diameter and wall thickness tolerances.

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 C1008, C1018, A36, A1011 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 P92 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.
