2507 Stainless Steel Bar S32750 1.4410

Composition and Characteristics

The superior performance of 2507 stainless steel is attributed to its carefully balanced chemical composition, which typically includes:

Chromium (Cr):24-26%

Nickel (Ni):6-8%

Molybdenum (Mo):3-5%

Manganese (Mn):1.2% max

Silicon (Si):0.8% max

Nitrogen (N):0.24-0.32%

Carbon (C):0.03% max

Phosphorus (P):0.035% max

Sulfur (S):0.02% max

This composition gives 2507 stainless steel its unique combination of high strength and excellent corrosion resistance. The high chromium, molybdenum, and nitrogen content enhances the alloy’s resistance to pitting and crevice corrosion, while the duplex structure provides superior mechanical properties, including twice the yield strength of conventional austenitic stainless steels.

Key Properties

2507 stainless steel bar is known for several key properties that make it an exceptional material for use in highly corrosive and high-stress environments:

Exceptional Corrosion Resistance:2507 stainless steel offers outstanding resistance to a wide range of corrosive environments, particularly those rich in chlorides. It is highly resistant to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for use in marine, offshore, and chemical processing applications.

High Strength and Toughness:The duplex microstructure of 2507 stainless steel provides significantly higher tensile and yield strength than standard austenitic stainless steels, allowing for the use of thinner, lighter sections without compromising structural integrity.

Good Weldability:Despite its high strength, 2507 stainless steel can be welded using most standard welding techniques. However, careful control of heat input and interpass temperature is necessary to maintain the duplex structure and avoid embrittlement.

Long-Term Durability:The combination of high strength and excellent corrosion resistance ensures long-lasting performance, even in the most challenging environments, reducing the need for frequent maintenance and replacements.

Non-Magnetic in Annealed Condition:The duplex structure results in a material that is non-magnetic when annealed, which can be advantageous in certain applications where magnetism is undesirable.

Applications of 2507 Stainless Steel Bar

2507 stainless steel bar is widely used in industries that demand materials with superior strength, corrosion resistance, and durability, particularly in highly aggressive environments. Common applications include:

Oil and Gas Industry:2507 stainless steel is extensively used in the oil and gas industry for components such as subsea pipelines, offshore platforms, and pressure vessels, where its high strength and resistance to stress corrosion cracking are critical.

Chemical Processing:The material is ideal for chemical processing equipment, including reactors, heat exchangers, and storage tanks, where exposure to corrosive chemicals and chloride-containing environments is common.

Marine and Coastal Applications:2507 stainless steel bar is used in marine applications such as seawater cooling systems, desalination plants, and shipbuilding due to its excellent resistance to seawater corrosion.

Desalination Plants:The alloy's resistance to chloride-induced corrosion makes it an ideal choice for desalination plants, where components are continuously exposed to highly corrosive seawater.

Pulp and Paper Industry:2507 stainless steel is also used in the pulp and paper industry for equipment like digesters and bleaching towers, where resistance to acidic and chloride-rich environments is required.

Advantages of Choosing 2507 Stainless Steel Bar

When selecting a material for applications requiring the highest levels of strength and corrosion resistance, 2507 stainless steel bar offers several significant advantages:

Unmatched Corrosion Resistance:2507 stainless steel is designed to withstand the harshest environments, offering resistance to stress corrosion cracking, pitting, and crevice corrosion, even in chloride-rich conditions.

Superior Mechanical Properties:The duplex structure of 2507 stainless steel provides twice the yield strength of conventional austenitic stainless steels, allowing for lighter, stronger components without sacrificing performance.

Long-Term Durability:The combination of high strength, toughness, and corrosion resistance ensures that components made from 2507 stainless steel have a long service life, reducing maintenance costs and downtime.

Versatility Across Applications:From oil and gas to marine environments, 2507 stainless steel bar is suitable for a wide range of demanding applications where performance and reliability are paramount.
