To know more about Alloy Steel ASTM A 182-F Flanges Manufacturer ASTM A182 is a standard specification for forged or rolled alloy and stainless steel materials, used for manufacturing pipe flanges, forged fittings, valves, fasteners and parts for high-temperature service applications. Boltport manufactures forged bolts, nuts, studs and other fasteners to ASTM A182 specification. Alloy Steel ASTM A 182-F Flanges specification covers requirements such as chemical composition, mechanical properties, heat treatment, welding repairs and other supplementary requirements for forged or rolled alloy and stainless steel materials used in pressure system.

According to the Alloy Steel ASTM A 182-F Flanges Manufacturer, ASTM A182 is a widely recognized specification for forged or rolled alloy and stainless steel pipe flanges, fittings, valves, and other components. ASTM A182 material is mainly used in high-temperature and high-pressure applications. This standardized specification, developed by the American Society for Testing and Materials (ASTM), outlines the mechanical and chemical properties required for the manufacturing of these critical components. In this blog post, we will delve into the features, applications, and benefits of ASTM A182, highlighting its significance in various industries.

Grades of ASTM A182 Materials

ASTM A182 covers a wide range of grades for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves. The grades of ASTM A182 material are designated by a combination of letters and numbers. Here are some of the commonly used grades:

• ASTM A182-F1: Low alloy steel is typically used for low-temperature service.
• ASTM A182-F5: Chromium-molybdenum alloy steel with enhanced high-temperature strength. Suitable for elevated temperature applications.
• ASTM A182-F9: Chromium-molybdenum alloy steel with improved creep resistance and resistance to high-temperature corrosion. Often used in refineries and power plants.
• ASTM A182-F11: Low alloy steel with enhanced creep resistance. Available in three classes: Class 1, Class 2, and Class 3.
• ASTM A182-F22:  Chromium-molybdenum alloy steel with excellent creep strength and resistance to oxidation and corrosion.
• ASTM A182-F91:  High strength, low alloy steel with good toughness and high-temperature strength. Suitable for power generation and petrochemical applications.
• ASTM A182-F304: Austenitic stainless steel with 18% chromium and 8% nickel. It is the most commonly used stainless steel grade.
• ASTM A182-F316: Austenitic stainless steel with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. It offers improved corrosion resistance compared to F304.
• ASTM A182-F321: Titanium-stabilized austenitic stainless steel with a similar composition to F304 but with added titanium for enhanced resistance to intergranular corrosion.
• ASTM A182-F347: Niobium-stabilized austenitic stainless steel with improved resistance to sensitization and intergranular corrosion.
• ASTM A182-F51 (Duplex Stainless Steel): A dual-phase stainless steel with a balanced combination of ferrite and austenite phases. It offers high strength and improved resistance to stress corrosion cracking.
• ASTM A182-F53 (Super Duplex Stainless Steel): A highly alloyed stainless steel with excellent corrosion resistance and high strength.
• ASTM A182-F55 (Super Duplex Stainless Steel): A super duplex stainless steel grade with enhanced resistance to corrosion and high mechanical strength.

The full form of ASTM is the American Society for Testing and Materials. It is an internationally recognized body. They are widely familiar as most oil and gas professionals must have referred to some of their standards. Founded in 1902, ASTM International develops and delivers voluntary consensus standards for improving product quality. These ASTM standards also make products safer and improve international standardization which in turn facilitates trade. In the year 2001, ASTM changed its name to ASTM International.

The standards developed and published by the ASTM include a wide range of materials, products, systems, and services. There are currently 12,575+ ASTM standards that are operating globally. The organization has its headquarters in West Conshohocken, Pennsylvania.

ASTM Standards

More than thirty thousand ASTM members from 140+ countries join together to provide their technical expertise for the development of ASTM standards used worldwide. The standards developed by the American Society for Testing and Materials serve more than 150 global industries. Some of the areas where ASTM standards are predominant are:
