Introduction
AzinForge Company, with the largest ring rolling machine in Iran, is able to produce industrial rings up to 5000 mm in diameter, 18 tons in weight, and 1500 mm in height. Industrial rings have diverse and important applications in various industries and are used in various industries including oil and gas, petrochemicals, power plants, mines, cement, etc. Alloy steel refers to steel in which, in addition to iron and carbon, other alloying elements such as manganese, nickel, chromium and molybdenum have been added. In this article, we will examine industrial rings made of alloy steel.

Industrial rings
Alloy steel is one of the most widely used materials in the manufacture of industrial rings due to its high strength, hardness, flexibility, and sometimes high resistance to corrosion.
Stages of industrial ring production
1- Initial forming: Steel ingots are converted into the initial form (preform) of the desired rings.
2- Rolling with a ring rolling machine: The raw materials on which the initial forming has been performed are transferred to the ring rolling machine and are formed into the desired shape according to the drawing.

3- Heat Treatment: AzinForge Company, utilizing various heat treatment equipment, including wagon and box furnaces, quench pools, is able to perform various heat treatments on parts, including the following:
- Annealing: Performed to reduce internal stress and soften the steel.
- Hardening/Quench and Temper: Steel is heated to high temperatures and then rapidly cooled to increase hardness.
- Normalizing: This process involves heating the steel to a temperature above the phase transformation temperature and then cooling it in air. The purpose of normalizing is to improve mechanical properties such as strength and hardness, as well as to create a fine-grained and uniform structure. Normalizing is used in particular to eliminate the effects of previous operations such as hot or cold working, and to achieve a homogeneous metallurgical structure.
- Tempering: After hardening, the part is heated to temperatures below the phase transformation temperature and then slowly cooled to achieve the right balance between hardness and toughness.
4- Machining: The rings are carefully machined according to the relevant part drawing to achieve accurate dimensions and a suitable surface.

Method of producing high-pressure rings
1- Forging
In the forging method, the metal piece is first heated and then shaped under the pressure of a die. This process creates a compact and resistant grain structure and is the best choice for producing high-pressure industrial rings.
Advantages:
High strength against pressure and impact
Excellent resistance to cracking and fatigue
Precise machining capability after forging
2- Ring Rolling
In this method, the metal is heated and rolled between two rollers to form a ring shape.
Ring rolling is mostly used for large rings with a diameter of more than 5000 mm.
Features:
Even stress distribution
Reduction in material waste
Smoother surface than traditional forging
3- Machining
For rings with small dimensions or low pressure, cutting and machining of steel billets may be used. Although this method is more economical, it has lower final strength.
Applications of industrial rings
Forged rings and high-pressure steel are used in various industrial sectors, including:
- Oil and gas industries: in flange connections, valves, gas transmission lines
- Petrochemical and refinery: for steam and high-pressure systems
- Power plants: in turbine and boiler equipment
- Hydraulic systems: in cylinders and high-pressure connections
- Food and pharmaceutical industries: with corrosion-resistant stainless steel materials
Final words
Industrial steel rings play a key role in improving the performance and efficiency of industrial machinery and equipment. Given the appropriate physical and chemical properties of these rings, their correct selection can help increase productivity and reduce maintenance costs. For this reason, it will be of great importance to pay attention to modern technologies in the design and production of these rings in the future.
