Chromium Molybdenum Alloy Steel or Chromium Molybdenum, CrMo is an alloy steel used for high temperature and high pressure service. Chromium molybdenum is used in power generation and petrochemical industries for its tensile strength, corrosion resistance and high temperature strength. Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

ASTM A194 2h nuts are available in nominal sizes ranging from ?” to 4″. These products are made with heavy duty hex nuts with different proof load stresses for regular nuts and zinc plated nuts. A194 2h coupling nut with 175ksi plain nut and 150ksi zinc plated nut. Fasteners of this grade of material also have high hardness.

Different types of ASTM A182 F5 forged fittings include threaded flanges, slip flanges, weld neck flanges, socket weld flanges, blind flanges and lap flanges.

These are said to be specifications for alloy flanges for high pressure and service. The 3% carbon content of these flanges provides a lot of room for improved weldability, which also increases their overall strength.

A335 P22 is a seamless tube made of ferritic alloy stainless steel. Chemically, the alloy of SA335 P22 material contains trace amounts of carbon, manganese, sulfur, silicon and phosphorus. The main additives in the alloy are molybdenum and chromium, which give stainless steel excellent mechanical properties. Tensile strength, corrosion resistance, hardness and other properties are enhanced and improved. Molybdenum reduces the brittleness caused by the addition of chromium.

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 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 carbon content in the Sa182 F9 flange is lower, so the weldability of this alloy is much better. Generally, higher carbon content in alloys promotes intergranular corrosion, especially during high heat treatments such as welding.

The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

ASTM A194 specification covers carbon, alloy and stainless steel nuts for high pressure and/or high temperature service. American National Standard Heavy Duty Hex Series (ANSI B 18.2.2) shall be used unless otherwise specified. Nuts no more than 1 inch in nominal size shall conform to UNC Series Class 2B.

Low alloy steel ASTM A182 F11 flanges typically have a total alloy content of 1.5% – 5%. Its common alloying elements are manganese, chromium, silicon, nickel, molybdenum and vanadium. It may contain up to four or five different quantities of these alloys. At the same time, the increased strength of the alloy steel F11 flange may require higher forming pressures. Annealing of SA 182 Gr F11 steel flanges is accomplished by water quenching by thorough immersion at 1725¡ãF – 1850¡ãF (941¡ãC – 1010¡ãC) and can only be hardened by cold work.

The alloying elements of A335 also impart higher corrosion resistance to the steel pipe. This also makes it the first choice for chemical companies.

Alloy steel pipes are common in applications involving automobiles, kitchenware, and industrial equipment. Typically, superalloy steel boiler tubes are used in applications with ambient temperatures exceeding 500¡ãC. For example, hollow and thin-walled alloy steel drill pipes must be able to resist pressure differences that manifest between the inside and the outside of these alloy steel seamless pipes.

In order to improve the thermal efficiency of the reheat steam pipeline of the power plant, the reheat temperature can be designed to be 621¡ãC, that is, the supercritical temperature. The United States first developed ASTM A335 P92 alloy steel in the late 1980s to meet the heat resistance requirements of this high temperature power plant. Alloy Steel P92 is an improved version of ASTM A335 P91 alloy with deliberate additions of tungsten, vanadium, niobium, reduced molybdenum content to fine-tune the ferrite/austenite ratio, and carefully controlled boron and nitrogen content.
