For A335 steel pipe, the addition of molybdenum (“Moly”) increases the strength and elastic limit of the steel, and enhances the wear resistance, impact quality and hardenability of the steel. It also improves softening resistance, makes chrome steel less brittle and prevents pitting corrosion. Chromium is also a key element in stainless steel alloys, preventing oxidation of the steel at high temperatures and improving the corrosion resistance of the steel. It improves the tensile, yield and hardness properties of low alloy pipes at room temperature.

When moving high-temperature or corrosive media through Chrome Alloy Pipe from one process to the next, flanges capable of withstanding harsh environments are critical

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.

Alloy steel seamless pipes are used in applications that require high precision for ease of installation and accuracy of operation and application. Different types are used for different mechanical benefits. Most applications require a lot of welding, so welding alloy steel pipes is good for them. Some are low in strength but high in corrosion resistance, and some are also high in strength. We offer high strength low alloy steel pipes in various grades and sizes.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.

The A182 F9 Alloy Steel Blind Flanges are used to close a connection opposed to all other flanges which extend the pipeline. Alloy Steel ASTM A182 F9 Flanges is connected to the pipe by welding the pipe to the neck of the pipe flange. However, the inside diameter of ASTM A182 F9 Alloy Steel Flanges is being designed to match the inner diameter of the pipe.

Alloy steels are used in boiler construction because they are inexpensive, readily available, easy to form and weld into desired shapes, and, in a wide range, have sufficient resistance to oxidation and corrosion to provide many industries with years of satisfaction service. Alloy steels are used in a range of demanding applications in the aerospace and power (nuclear) industries. Alloy steels are also found in applications where their response to magnetism is important, such as in transformers and electric motors.
