Product Features



In Terofox Valves, we understand that standard materials are not suitable for every application. We also know that our customers need a wide range of options that can satisfy their every demand, that’s why we offer our Special Alloy Valves, mainly used for different degrees of corrosion resistance. 

Material Code Applications
Austenitic Stainless Steel  
Alloy 20 -        Superior resistance to stress-corrosion,
preventing cracking in boiling at 20% to 40% sulfuric acid.
Super Austenitic Stainless Steel  
254 SMO -        High resistance to pitting, crevice and general corrosion.
-        Very high resistance to chloride stress corrosion cracking.
Nickel based Alloy  
Monel 400 -       Good resistance against corrosion by acids and oxygen makes Monel suitable for the chemical industry.
Hastelloy C -       Effective survival under high-temperature.
-       Can outlast a moderately to severely corrosive environment.
Duplex Stainless Steel  
2205/4A -        2205 is a duplex stainless steel designed to combine improved resistance to stress corrosion cracking, pitting, crevice corrosion and stronger when compared with other stainless alloys.
Super Duplex Stainless Steel  
2507/5A -       Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. 
Titanium  
Grade 2 -       Titanium Grade 2 is used commonly in applications that require welding because of its strong weldability properties. Titanium Grade 2 is light weight and highly corrosion resistant.
