L80-13Cr
is a special type of alloy steel with excellent resistance to chemical
corrosion. It is mainly used to prevent various forms of corrosion, including
oxidation, electrochemical corrosion, and chemical erosion. In many cases, it
can withstand a variety of harmful acids and alkalis. It has good wear
resistance and hardness, good cold and hot working properties, relatively low
cost, and a long service life, making it popular in many industries.
Moreover,
this material can be used in any environment where excellent corrosion
resistance is required, such as chemical plants, power plants, and water
treatment stations. Because of its excellent properties, the value of this
material is constantly increasing. In summary, L75-ISCR is a very practical
corrosion-resistant product.
China has
been engaged in research and development of 13Cr martensitic stainless steel
oil and casing tubes resistant to CO2 and H2S corrosion for several years.
Currently, Baosteel and Tianjin Pipe have developed a series of 13Cr and super
13Cr products, which have been applied in major oil fields such as Tarim,
Xinjiang, Xi'an Changqing, and Shengli, and have also been exported to the
United States, Canada, and other countries.
At present,
13Cr martensitic stainless steel has been basically domesticated in China and
has partially replaced imported products. Due to the higher alloy element
content and manufacturing costs of duplex stainless steel and nickel-based
alloys, Chinese steel pipe enterprises can, based on their existing experience
and technological accumulation in ordinary 13Cr, continuously improve smelting,
pipe rolling, and heat treatment processes through laboratory alloying research
to develop high-chromium martensitic stainless steel oil and casing tubes with
excellent comprehensive properties.
With fast
delivery and high quality, we help customers reduce costs and increase
efficiency. Our vision is to build an international petroleum pipeline
equipment enterprise through integrity and innovation. We welcome leaders and
friends from all sectors to visit and cooperate for mutual development.
