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.

Inconel600 is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten electrode inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, molten arc inert gas shielded welding, and pulsed arc welding. Welding is the preferred solution. When using manual arc welding, it is recommended to use a shielding gas mixed with various components (Ar+He+H2+CO2).
Welding of Incoloy 825 must be carried out in the annealed condition and cleaned with a stainless steel wire brush to remove stains, dust and various markings. When welding the root of the weld, extreme care must be taken (Argon 99.99) to obtain the best quality of the root weld so that the weld does not produce oxides after the root has been welded. Color from the weld heat-affected zone should be removed with a stainless steel brush while the weld area is not cool.

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.

WPHY 52 Fittings are recommended be heat treated by one or more of the following procedures: annealing (stress relieving), normalizing, normalizing and tempering, quenching and tempering.Made utilizing high-grade crude materials, these ASTM A860 WPHY Pipe Fittings are anti-corrosive and strong.

In applications where higher working pressures are a prerequisite, the use of seamless pipes is justified. Although stronger than welded pipe, the cost is much higher. In addition, in welded products, there is a greater risk of intergranular corrosion in the heat-affected weld zone. The obvious difference between alloy steel welded pipe and seamless product is the transverse seam along the length of the pipe

These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments. A182 Gr F5 Threaded Flanges are mostly used in utility services such as air and water. It is similar to the Slip-On flange, but the bore is threaded. Its greatest advantage is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.

These ASTM A182 alloy steel F12 flanges are corrosion resistant. ASTM A182 alloy steel F12 flanges also have high dimensional accuracy.

A182 alloy steel flanges are not only suitable for high temperature, but also for high pressure or a combination of the two.

The ASTM A320 specification, originally approved in 1948, covers alloy steel and stainless steel bolting materials for low temperature service.

ASTM A182 F5 flanges are a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also facilitates cleaning, inspection or modification.

There is absolutely no risk of intercrystalline corrosion on cooling or welding in Alloy Steel(AS) F12 Slip-on Flanges due to the low carbon content.Alloy Steel F12 Weld Neck Flanges is appropriate to various applications where its different remarkable characteristics are sought-after but a brushed/polished finish is not necessary.

ASTM A193 Grade B7 Heavy Duty Hex Head Bolts are high strength fasteners made from heat treated alloy steel AISI 4140/4142 quenched and tempered.

The ANSI B16.5 Alloy Steel Slip On Flange is a flange type that allows the pipes to slip onto the flange and makes the connection in a precise locations.

Our Alloy Steel Seamless Pipes (IBR) are made of alloy steel with excellent properties. These were developed for energy-related applications involving oil and gas drilling and are therefore subject to the stress of machine parts. In addition, alloy steel pipes are used in domestic, professional or industrial fields.
