09CuPCrNi-A weathering steel: excellent performance, widely used

concept

Cupcrni-a weathering steel, also known as corrosion resistant steel or Corten steel, is A low alloy steel series between ordinary steel and stainless steel. By adding niobium, molybdenum, phosphorus, titanium and other weather-resistant elements into the steel material, a dense oxide layer is formed between the rust layer and the substrate. This dense oxide film can prevent atmospheric oxygen and water from penetrating into the steel matrix, thereby slowing the development of corrosion into the steel material, giving the steel excellent weather resistance and corrosion resistance. Mechanical property

09CuPCrNi-A weathering steel has excellent mechanical properties, mainly including the following aspects:

Yield strength: about 275MPa, showing good pressure resistance.

Tensile strength: about 390MPa, can withstand a large tensile force without breaking.

Elongation: about 31%, showing good plastic deformation ability.

Hardness: about 150HB, with certain wear resistance and scratch resistance.

Scope of application

09CuPCrNi-A weathering steel is widely used in many fields because of its unique properties:

Bridge construction: In bridge construction, 09CuPCrNi-A weathering steel is favored for its excellent weather resistance and corrosion resistance. It can maintain stable performance in harsh climatic conditions for a long time, greatly extending the service life of the bridge. At the same time, its good mechanical properties and welding properties also make the construction process of the bridge more convenient and safe.

Transportation infrastructure: In the construction of transportation infrastructure such as railways and roads, 09CuPCrNi-A weathering steel also plays an important role. Its weather resistance and corrosion resistance ensure that the infrastructure is not vulnerable to damage during long-term use, reducing maintenance costs. At the same time, its good plasticity and machinability also make it able to meet a variety of complex construction needs.

Construction industry: 09CuPCrNi-A weathering steel is also widely used in the construction industry, such as for the manufacture of external walls, roofs and other structural parts. Its excellent weather resistance allows the building to maintain its beauty and practicality in the outdoor environment for a long time.

Marine engineering: In Marine engineering, 09CuPCrNi-A weathering steel can be used to manufacture offshore platforms, ships and other equipment. Its corrosion resistance enables the equipment to operate stably in the Marine environment for a long time.

Petrochemical: In the petrochemical industry, 09CuPCrNi-A weathering steel can be used to manufacture storage tanks, pipelines and other equipment. Its excellent corrosion resistance ensures that the equipment is not easily damaged in harsh chemical environments.
