Monel is widely used in many fields, especially marine and chemical processing.
Monel is a kind of corrosion-resistant alloy with the largest amount, the most extensive use and excellent comprehensive properties, bearing excellent corrosion resistance in hydrofluoric acid and fluorine medium as well as in hot concentrated alkali solution.
Nickel aluminum bronze is mainly composed of nickel and ferromanganese.
With excellent corrosion resistance, nickel aluminum bronze acts as an important material for marine propellers, pumps, valves and underwater fasteners, being widely used in seawater desalination, petrochemical industry, ocean engineering, coal chemical industry, pharmacy and pulp & paper making industry.
JST has manufacturer of Nickel 200 and Nickel 201 valves, these material valves are primarily selected for use in high temperature and or corrosive environments.
Nickel 200 is commercially pure (99.6%) wrought nickel. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content and low vapor pressure.
Being able to withstand ultra-high pressure from 0.0013 MPa to 1000 MPa and ultra-high temperature from – 269 to 1430 ℃, stainless steel valves are widely used to control the flow of fluids such as air, water, steam, corrosive medium, mud, oil, liquid metal and radioactive medium.
Super austenitic stainless steel valves have great resistance against pitting and crevice corrosion of chloride owe to its super austenitic stainless steel has high molybdenum content (>6%) and nitrogen additions.
This steel features high corrosion resistance rivaling nickel-based alloy at a significantly lower cost.
With excellent chemical properties and high corrosion resistance, tantalum valves do not react to hydrochloric acid, concentrated nitric acid and aqua regia under cold and hot conditions, and will not be corroded by concentrated sulfuric acid below 150°C temperature.
Tantalum valve is used more and more widely because of its little corrosion and long life in strong corrosive environment.
Titanium and titanium alloys are non-ferrous high chemical activity metals. Titanium materials have oxide films, good stability and self-passivation ability in strong corrosion environment, so titanium valves can resistance a variety of harsh corrosion conditions.
