A335 P22 pipes are Seamless ferritic Alloy Steel Pipes. A335 P22 pipe specification are many and all of these can be found right here at our website. A335 P22 pipe is sort of chrome moly pipes and these pipes have been listed in ASTM A335. The Heat Treatment required for A335 P22 pipes are full or isothermal anneal and for subcritical annealing or tempering, the temperature range is 675 degrees Celsius (1250 degrees Fahrenheit.) Mechanical properties of A335 P22 pipes are that they have a minimal Elongation Percentage of 30/20. Their minimum Tensile Strength is 415 Mpa and the minimum Yield Strength is 205 Mpa.
A335 P22 pipes are used in various industries, where hygiene is of the utmost importance. ASTM A335 P22 pipe applications, because of their being cost-effective, their high resistance to corrosion, high temperature strength and their tensile strength, they are very popular in many industries, such as paper, power generation, engineering, textile, powder, sugar, nuclear, petrochemical, dairy, water treatment plants, etc. A335 P1 seamless pipe is best for fusion welding, bending, flanging, and various other operations of a similar nature. A335 P22 pipes are used in many applications, where the use of high temperature is involved.
An important factor to note about P22 material composition & welding procedure is that A335 is referred to as chrome moly pipe and the reason for this is because it contains Molybdenum (Mo), as well as Chromium (Cr). Molybdenum plays a major role in A335 P22 pipes, as it makes the pipe's resistance to wear, increases its impact qualities, increases the hardenability of the pipes, increases the elastic limit and it also increases the steel strength. The welding procedures for P22 material could be that of fusion welding, GTAW, ER80S-B6, ER80S-B2, ER90S-B9, etc.
Small and medium diameters ASTM A335 Grade P22 Pipes are produced in continuous, multiple-roll mills that progressively bend the incoming, unheated strip into a circular cross-section prior to welding along the longitudinal seam. High Pressure Alloy Steel P22 Boiler Pipe may subsequently be cold-drawn through dies to achieve precise dimensions and finish. Small bore/diameter SA335 P22 Pipe that has been produced by electric resistance welding (ERW) without drawing or annealing. Our selection of ASTM A335 P22 Pipe, ASTM A335 P22 Welded Pipe, and ASTM A335 Alloy Steel P22 EFW Pipe includes hollow sections, black and galvanized gas/water pipe, scaffolding tube, and large diameter pipe. Large diameters (400-1,600mm) AISI P22 ERW Pipes are made from a plate which is welded in an ‘O’ shape before being mechanically or hydraulically expanded.

ASTM A335 P22 Seamless Pipe
P22 Seamless Pipe and Alloy Steel P22 Pipe are suitable for high temperature application such as flanging (vanstoning), bending, and similar forming operations, and for fusion welding in the petrochemical plants and power industry. ASTM A335 gr P22 Pipe (ASME S/A335, Chrome-Moly) is a seamless ferritic Alloy Steel Pipe for high-temperature service. ASME SA 335 Alloy Steel P22 Seamless Pipe is also known as ASTM A335 P22 chrome moly pipe because of the chemical makeup of Chromium (Cr) and Molybdenum (Mo). Molybdenum maintains the strength of P22 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 P22 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 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 P22 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.
