2507 is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of a variety of ferritic steels and austenitic steels. Due to its high chromium and high molybdenum content, it has excellent resistance to corrosion. Pitting corrosion properties, while crevice corrosion and homogeneous corrosion.
Alloy 2507 (UNS S32750) consists of 25% chromium, 4% molybdenum and 7% nickel. It has strong strength and corrosion resistance and is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient.

2507 stainless steelis used in the oil and gas industry; offshore Shipotian oil platforms (water treatment and water supply systems, fire protection systems, sprinkler systems, water stabilization systems, petrochemical equipment, desalination (desalination) equipment and high-pressure pipes, seawater pipes in equipment ); the simultaneous presence of mechanical and structural components that require high strength and high corrosion resistance; combustion (waste) gas purification equipment.
2507 stainless steelhas been widely used in the petroleum, chemical industry, marine, and pharmaceutical fields. For example, it is used to manufacture oil well pipelines, chemical equipment, offshore platforms, ships and storage tanks, etc. In addition, it can be used to manufacture food processing equipment, bearings automotive parts, etc.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
