ASTM A335 P91 K91560 Alloy Steel Seamless Pipe for High Temperature
What is ASTM A335?
This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for hightemperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.

A335 is often called chrome moly pipe because of the chemical makeup of Mo and Cr. Mo increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel, and inhibits pitting.

Size Inspection
A335 seamless steel pipe is a popular choice for high temperature applications due to several key reasons:
High temperature resistance: A335 seamless steel pipe is designed to withstand temperatures up to 600°C (1112°F), making it an ideal material for high-temperature applications such as steam pipes and heat exchangers.
Corrosion Resistance: A335 seamless steel pipe exhibits good corrosion resistance in corrosive environments, such as those found in chemical processing and the oil and gas industry.
High Strength: A335 seamless steel pipe has high tensile strength and yield strength, making it ideal for high-pressure applications.
Good weldability: A335 seamless steel pipe can be easily welded using traditional methods without preheating or post-weld heat treatment.
Applications
ASTM A335 Alloy Steel P91 is commonly used in power plants, refineries, and other industrial settings where high-temperature and high-pressure conditions are present. It is used in boilers, heat exchangers, and other equipment that requires high-temperature resistance and corrosion resistance.
