Corrosion Resistant 2507 Duplex Stainless Steel Bar F53 Black Rod Seamless Pipe

Product Specification

Corrosion Resistant 2507 Duplex Stainless Steel Bar F53 Black Rod Seamless Pipe Cutting.

F53 is a duplex stainless steel, also known as UNS S32750 or 1.4410. This stainless steel has excellent corrosion resistance and strength due to its high content of elements such as chromium, nickel, molybdenum, and nitrogen. F53 stainless steel belongs to super duplex stainless steel, which combines the beneficial properties of ferritic steel and austenitic steel, with high corrosion resistance, high strength and hardness, as well as good fatigue resistance and stress corrosion cracking resistance. Its main components include chromium, nickel, molybdenum, and nitrogen, among which the addition of molybdenum and nitrogen significantly improves the corrosion resistance and stress corrosion cracking resistance of stainless steel. ‌

The main chemical components of F53 stainless steel include:

Carbon (C): not exceeding 0.030%
Silicon (Si): not exceeding 0.80%
Manganese (Mn): not exceeding 1.20%
Phosphorus (P): not exceeding 0.035%
Sulfur (S): not exceeding 0.020%
Chromium (Cr): 24.00~26.00%
Nickel (Ni): 6.00~8.00%
Molybdenum (Mo): 3.00~5.00%
Nitrogen (N): 0.24~0.32%
Copper (Cu): not exceeding 0.5%

The precise balance of these elements in F53 stainless steel endows it with outstanding performance.

The advantages of F53 stainless steel mainly include high strength and hardness, excellent corrosion resistance, good welding performance, stress corrosion cracking resistance, good surface quality, superior mechanical properties, good processing performance, and wide application. ‌

F53 stainless steel is a ferritic austenitic (duplex) stainless steel, and this duplex structure endows it with a series of unique advantages:

High strength and hardness: F53 stainless steel, due to its dual phase structure, has high strength and hardness, making it exhibit excellent durability in high temperature and high pressure environments.

Corrosion resistance: F53 stainless steel has excellent corrosion resistance and can resist corrosion from various chemical media, including acids, alkalis, chlorides, and seawater.

Stress corrosion cracking resistance: F53 stainless steel has good resistance to stress corrosion cracking and can maintain its integrity in high stress and corrosive environments.

Good welding performance: F53 stainless steel has good welding performance and can be welded through conventional methods such as arc welding and TIG welding.

Impurity control: Strictly control the impurity content during the manufacturing process to ensure the uniformity and purity of the material.
Superior mechanical performance: The high strength, good ductility, and strong toughness of F53 stainless steel strip make it very suitable for situations that require high load and strength.

Strong corrosion resistance: F53 stainless steel strip has extremely strong corrosion resistance and can be used for a long time in harsh environments without rusting or corrosion.

Good processing performance: F53 stainless steel strip has excellent processing performance, easy to cut, weld, form, etc., and is not prone to surface damage such as scratches and bumps.

Widely used: F53 stainless steel has a wide range of applications, including the manufacturing of high-precision instrument components and key components for large equipment. It is widely used in industries such as ships, offshore oil and gas platforms, chemical, petroleum, and food.
