Duplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel whose structure is a balance of ferritic and austenitic.

2304 Duplex Stainless Steel PlateDuplex 2304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless metal whose shape is a stability of ferritic and austenitic. It has common corrosion resistance comparable or higher than Alloys 304L and 316L however with yield energy almost double that of austenitic stainless steels.

Hastelloy C-4 Seamless PipeHastelloy C-4 alloy is a nickel-chromium-molybdenum alloy with outstanding high-temperature stability as evidenced by high ductility and corrosion resistance even after aging in the 1200 to 1900°F (649 to 1038°C) range. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.

Duplex 2304 is two-phase, ferritic, austenitic which contain chromium 23%,nickel 4%, molybdenum-free duplex stainless steel. Itscorrosion resistance properties are similar to 316L stainless steel. Furthemore it has mechanical properties twice to 304L stainless steel/316Lstainless steel grades. And this becomes helpful for the manufacturers to save weight especially for properly designed pressure vessel applications.

Duplex 2507 Stainless Steel PlateAlloy 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion.

We make use of hundred percent pure raw materials for manufacturing Duplex S31803 Coils that results in the production of high quality of goods. Duplex 31803 Coils has a huge number of applications in various industries. These coils are used in the manufacturing of the piping and tubing in the oils and gas exploration industries and are also used in the manufacturing of food processing equipment.

Duplex stainless steel tube has good welding performance, compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat affected zone of ferritic stainless steel, because of the severe coarsing grain and the plastic toughness is greatly reduced, nor like austenitic stainless steel, is more sensitive to welding hot crack.Because of its special advantages, duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, papermaking machinery and other industrial fields.

HASTELLOY C-4 alloy has exceptional resistance to wide variety of chemical process environments.
