Spot Sales of L80-13Cr Oil Tubes and Casing

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.
