Tấm Uns S32750
UNS S32750 sheet is a super duplex stainless steel material with outstanding strength and excellent corrosion resistance. Crôm cao của nó, molypden, and nitrogen content make it highly resistant to chloride and seawater corrosion.
Because of its superior mechanical and corrosion-resistant properties, UNS S32750 is widely used in oil and gas, kỹ thuật hàng hải, xử lý hóa chất, and high-performance industrial systems where standard stainless steels are not sufficient.
- Sự miêu tả
UNS S32750 sheet is a super duplex stainless steel material with very high strength and excellent corrosion resistance. It is commonly known as 2507 super duplex stainless steel and is widely used in harsh industrial environments where ordinary stainless steels cannot provide sufficient performance.
The microstructure of UNS S32750 combines:
- Austenitic stainless steel characteristics
- Ferritic stainless steel characteristics
This dual-phase structure gives the material both high mechanical strength and strong corrosion resistance.
Chemical Composition of UNS S32750
UNS S32750 contains high levels of chromium, molypden, và nitơ, which significantly improve corrosion resistance.
