High Yield Flanges
We also offer higher yield variants of carbon steel flanges like F52, F60, F65, and F70 (all per A694).
These are heat treated carbon steel with a higher yield strength than common A105 flanges with a 35K yield strength minimum.
If your application calls for low temperature service, consider A350 LF2 carbon flanges (with Charpy V-Notch Impact Tests at -50°F) or the superior LF3 (CVNs at -150°F)
Why Use High Yield Carbon Steel Flanges?
The yield strength is a characteristic of steel in which the material in question can withstand deformation. The point of stress in relation to said material in which plasticity deformation occurs is known as the yield point. This point is the maximum allowable load bearing occurrence upon which the steel material should be subjected. Yielding is a gradual failure measure which occurs over a period of time and in which case deformation is observable.
A carbon steel heat treated variant with an increased yield strength (the point at which metal undergoes deformation) are most commonly used in applications of higher pressure and temperature, with flanges usually being class 600# and higher.
They are also less brittle compared to mild steel and have a slightly higher carbon content to make this possible. Their overall resistance to wear is their most important quality in applications which require a longer life service.
As mentioned previously, the specifications A694 and MSS-SP44 govern the details of this category of metals ranging from grades F42 to F70.
Our High Yield A694 flanges are often normalized to maintain a superior grain structure.

Frequently Asked Questions (FAQs)
High-yield flanges are specialized components crafted from high-strength, low-alloy steel. This unique material composition provides them with a significantly higher yield strength compared to standard carbon steel flanges.
Yield strength refers to the material's ability to withstand force without permanent deformation, making high-yield flanges an essential choice for demanding industrial applications.
High-yield flanges offer several notable benefits, making them a preferred choice in many engineering and industrial settings. They are significantly stronger and lighter than traditional carbon steel flanges.
This combination of strength and reduced weight allows for more efficient designs, particularly in systems that must handle high pressures, extreme temperatures, or persistent vibrations. Additionally, their robust material properties often result in better durability and reliability, reducing the need for frequent replacements or maintenance in critical operations.
High-yield flanges are ideal for applications requiring exceptional strength, lightweight components, and resistance to challenging conditions.
They are commonly used in industries such as oil and gas, petrochemical processing, and power generation, where systems are exposed to high pressure, elevated temperatures, or continuous vibrations. For projects requiring stringent safety and performance standards, high-yield flanges are often indispensable.
While high-yield flanges provide significant advantages, their higher cost compared to standard carbon steel flanges can be a limiting factor. They are not recommended for use in applications where the operating conditions are moderate or where cost-efficiency is a primary concern.
For instance, if a system operates under low pressure and temperature and is not subject to excessive vibration, the additional strength of high-yield flanges may not justify the expense.
High-yield flanges are available in a variety of types to suit different industrial needs. Common options include slip-on flanges, which are easy to install and align; threaded flanges, which allow for quick assembly without welding; weld neck flanges, designed for high-stress applications and providing superior stress distribution; and socket weld flanges, ideal for small-diameter, high-pressure piping systems.
Each type serves a specific purpose, ensuring the right fit for various engineering challenges.
