A high quality chrome molybdenum alloy steel plate intended
specifically for use in weldable carbon steel pressure vessels at
elevated temperatures. Added molybdenum gives the material greater
temperature tensile strength and the chromium provides improved
Weldable carbon steel plates for pressure vessels and boilers used
in elevated temperatures. The material benefits from added chromium
and molybdenum which gives the steel greater corrosion resistance
and resistance to heat. A/SA387 Grade 9 is used by fabricators who
serve the oil, gas and petrochemical industry.
A pressure vessel grade steel for use in elevated temperature
service, ASTM A387/ASME SA387 Grade 11 Class 2 is used in a variety
of industries and is highly effective, particularly in the oil, gas
and petrochemical industry, where liquids and gases are often
stored at higher temperatures.
The higher levels of chromium also provide excellent corrosion and
oxidation resistance, which is a must in sour gas applications.
Engineered for use in elevated temperature service, ASTM A387/ASME
SA387 Grade 12 is a chrome molybdenum carbon alloy steel for use in
weldable pressure vessels and industrial boilers.
The material benefits from added chromium which provides excellent
corrosion and oxidation resistance making it ideal for sour service
applications in the oil and gas industry.
We supply A/SA387 Grade 22 Class 2 plates to fabricators serving
the oil, gas and petrochemical industry. These industries require a
pressure vessel grade steel which works well in elevated
temperatures and our material serves this purpose well. And with
good corrosion and oxidation resistance, A/SA387 Grade 22 Class 2
plates are a good option.
Where resistance to high temperature and good anti-corrosion
characteristics are required, A/SA387 Grade 91 Class 2 carbon alloy
steel plate is a material to consider. It is a pressure vessel
grade steel which is used commonly by fabricators who supply the
oil and gas industry.
Due to the materials excellent corrosion resistant properties,
A/SA387 Grade 91 is also an option for use in sour service
environments. The material has good weld-ability and with its heat
resistant qualities, the material is a highly versatile steel which
can be used in numerous applications.
