Molybdenum Feature
The A335 pipes has a high level of Chromium and Molybdenum presence
in it. While Molybdenum increases the overall strength, resistance,
elasticity, hardenability and overall quality, moly ensures that
the material is more resistant to softening, restrains the growth
of grains and lessens the chances of embrittlement. It is the
single additive that is responsible for the increase in high
temperature resistance and it also improves the corrosion
resistance to steel
ASTM A335 Feature
High-temperature resistance: ASTM A335 seamless steel pipe is
designed to withstand high temperatures up to 600°C (1112°F),
making it an ideal material for high-temperature applications such
as steam pipelines and heat exchangers.
Corrosion resistance: ASTM A335 seamless steel pipe exhibits good
corrosion resistance in aggressive environments, such as those
found in chemical processing and oil and gas industries.
High strength: ASTM A335 seamless steel pipe has high tensile
strength and yield strength, making it ideal for use in
high-pressure applications. Good weldability: ASTM A335 seamless
steel pipe can be easily welded using traditional methods, with no
need for preheating or post-weld heat treatment.
Uniform properties: ASTM A335 seamless steel pipe is produced using
a consistent manufacturing process, ensuring that each pipe has
uniform properties and quality.
Cost-effective: Despite its superior properties, ASTM A335 seamless
steel pipe remains an affordable option for high-temperature
applications.

Corrision resisitance
Alloy Steel Grade P11 is an ideal material for industrial
applications that require corrosion resistance, particularly in
hostile and marine environments. In addition to low carbon, sulfur,
and phosphorus content, this alloy steel grade has Chromium,
Molybdenum, and Manganese which give it superior corrosion
protection compared to other stainless steel alloys. Grade P11 is
extensively used in the production of pipes and tubes, valve parts,
and flanges.
Heat Resistance
Alloy Steel Grade P11 stands out due to its incredible heat
resistance. It provides the user with better protection against
ultra-high temperature stress and strain, wears, and oxidation than
traditional carbon steel. Furthermore, it is well suited for
cryogenic temperatures and has excellent toughness at both subzero
and elevated temperature conditions.
