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. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

The main components of ASTM A335 grade P91 are also molybdenum (Moly) and chromium (Chrome). These elements provide pipes with specific properties such as enhanced corrosion resistance and increased overall strength, creep resistance and wear resistance.

These ASTM A182 alloy steel F5 F9 F11 F12 F22 F91 pipe fittings are corrosion resistant. ASTM A182 alloy steel F5 F9 F11 F12 F22 F91 fittings also have high dimensional accuracy.

There are different types of fittings such as bends, tees, crosses, reducers, caps and the WPHY 52 Elbow.In sour service wells, when hydrogen sulphide gas reacts with water, the hydrogen molecule gets deposited either on the pipes or fittings.

It has chemical composition, such as nickel, nickel-chromium, molybdenum, chromium-molybdenum steels etc.

The composition of A335 P91 material contains carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium, nitrogen, nickel, aluminum, niobium, titanium and zirconium. There are two kinds of seamless pipes and welded pipes. Seamless pipe is drawn from a single raw material billet, while ASTM A335 Gr P91 Welded Pipe is welded from strip or sheet. Welding can be helical or longitudinal from one end to the other to produce the tube. The minimum yield strength of the pipe is 415MPa and the minimum tensile strength is 585MPa.

We can supply chrome molybdenum alloy flanges sorted by alloy grade, size and pressure.

Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.

Alloy steel pipes and tubing are the best choice for stress corrosion cracking (SSC). These also apply to environments where the problem is pitting and crevice corrosion. These tubes and tubes are available within machining allowances and tolerances.

The manufacturing process of A860 WPHY 52 includes heat treatment.

800H can resist corrosion of many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.

The a182 f9 material contains a certain amount of chromium and molybdenum, both of which contribute to a longer service life and therefore longer life.

The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation.

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.

The carbon content of 4140 alloy steel pipe is 0.38-0.43%, the manganese content is 0.75-1.00%, the phosphorus content is 0.04%, the sulfur content is 0.04%, the silicon content is 0.15-0.35%, the chromium content is 0.8-1.10%, and the molybdenum content is 0.8-1.10%. is 0.15-0.25 % maximum in its composition. The material can be heat treated to anneal and normalize in air, or quench and temper in polymer or oil.

ASTM 182 is used for pressure systems, including flanges, fittings, and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.

Chromium (or chromium) in A335 is an essential element in stainless steel production. Steel products are defined as stainless steels with 12% or more chromium added. Chromium is widely used due to its excellent heat resistance properties and is irreplaceable in terms of resistance to oxidation in high temperature applications.
