ASTM A213 Grade T5 Seamless Alloy Steel Pipe

ALLOY pipe

ASTM A213 is the standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Grade : T2, T5, T5b, T5c, T9, T11, T12, T17, T21, T22, T23, T24, T36, T91, T92, T122, and T911. The tubing sizes and thickness usually furnished to this specification are 1/8″(3.2 mm) in inside diameter to 5″(127 mm) in outside diameter and 0.015″ to 0.500″(0.4-12.7 mm) in minimum or average wall thickness. ASTM A213 tubes of custom-diameter may be furnished, provided such tubes comply with all other requirements of the standard specification.

ALLOYING ELEMENTS

The addition of Molybdenum (“Moly”) increases the strength of the steel and its elastic limit, enhance the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement and prevents pitting.

Chromium, a key element also for stainless steel alloys, prevents steel oxidation at elevated temperatures and increases the resistance of steel to corrosion. It enhances the tensile, yield, and hardness properties of low-alloy pipes at room temperatures.
Other alloying elements, present in various degrees in pipes of all grades are:

  • Aluminum: decreases oxygen from steelmaking
  • Boron: used to produce fine grain size and enhance steel hardness
  • Cobalt: used to enhance the steel’s heat and wear-resistance
  • Manganese: gives better steel hardenability
  • Nickel: Enhances toughness, hardenability and impact strength at low temperatures
  • Silicon: decreases oxygen, enhances hardenability and toughness
  • Titanium: prevents precipitation of chromium carbide
  • Tungsten: refines steel grain size and enhance the steel hardness, especially at high temperatures
  • Vanadium: gives steel enhanced fatigue resistance

As mentioned, low-alloy steels have a total amount of alloying elements below 5%; high alloy steel has a higher percentage of these elements.
