Introduction of ASME SA335 P11 Alloy Steel Seamless Pipes

The UNS designation for this P11 grade is K11597. The main components of P11 pipes are carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum. The main components are chromium and molybdenum, and it has excellent strength, wear resistance, hardenability, and corrosion resistance.

Alloy Steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "Alloy Steel " refers to low-alloy steels. Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "Alloy Steel " is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.

The following is a range of improved properties in Alloy steels (as compared to) Carbon steel : strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. to achieve some of these improved properties the metal may require heat treating.

Advantages of ASME SA335 P11 Alloy Steel Seamless Pipe

  • High Temperature Resistance: With chromium and molybdenum as key alloying elements, P11 pipes can withstand high temperatures without losing strength, which is critical for applications like steam boilers and other high-temperature equipment.
  • Corrosion Resistance: The chromium content enhances the pipe's resistance to oxidation and corrosion, extending its lifespan even in harsh environments.
  • Mechanical Strength: The combination of chemical elements provides a balance of strength and flexibility, reducing the risk of failure under stress.

ASTM A335 P11 Pipe is part of ASTM A335. The pipe must be suitable not only for fusion but also for forming operations such as bending and flanging. Steel materials have chemical composition, tensile properties, and hardness requirements. Each length of pipe must be hydrostatically tested. Additionally, each pipe must be inspected using non-destructive testing methods in accordance with required practices. Various mechanical testing requirements for pipes are presented, namely transverse or longitudinal tensile tests, flattening tests, and hardness or bending tests. Order numbers are located on both ends of each box. Heat number, dimensions, weight, bundles or as per your request.

ASME SA335 P11 Seamless Pipes

Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service

This specification2 covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high temperature 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.

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as “P Grade”, Chrome Moly Pipe is popular in Stainless Steel Tubes P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.

A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum 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. Chromium (or chrome) is the essential constituent of Stainless Steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile, yield, and P11 Material Hardness value at room temperatures. The composition chrome moly Alloy Steel pipe and Alloy Steel Tubes make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.
