UNS S32750 F53 Duplex Stainless Steel / Alloy Light Rod Steel Pipe Steel Plate

High strength and hardness duplex stainless steel rod UNS S32750/F53 alloy light rod steel pipe steel plate

Introduction to S32750 Bidirectional Stainless Steel

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. ‌
