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:
| content | C | Si | Mn | P | S | Cr | Ni | Mo | N | Cu | other elements |
| ≤0.03% | ≤0.80% | ≤1.20% | ≤0.035% | ≤0.020% | 24.00%~26.00% | 6.00%~8.00% | 3.00%~5.00% | 0.24%~0.32% | ≤0.50% | margin |
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%

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.
