Every steel is an alloy, but not all steels are labeled ‘alloy steel’.  An alloy steel is a steel that is alloyed with various elements to improve its mechanical properties. A small percentage of alloying elements - typically, no more than 5% - is added to the mix, and these metals can improve corrosion resistance, machinability, and many other properties. Alloy steel has some of its properties better than carbon steel. Alloys such as 9Cr, 4140 and F22 have been designed to withstand these harsh environments.

Useful information about Alloy steel

Alloying elements in Alloy steel
  • Manganese: Used in tandem with small amounts of sulfur and phosphorus, the steel alloy becomes less brittle and easier to hammer.
  • Chromium: A small percentage (0.5% – 2%) can help to harden the alloy; larger percentages (4% – 18%) have the added effect of preventing corrosion.
  • Vanadium: With only .15%, this element can boost strength, heat resistance, and overall grain structure. Mixed together with chromium, the steel alloy becomes much harder, but still retains its formability.
  • Nickel: Up to 5%, this alloying element will improve the steel’s strength. In excess of 12%, it provides impressive corrosion resistance.
  • Tungsten: Boosts heat resistance, so the melting point is higher. Also improves the structural makeup of the steel.
Low alloy steel vs high alloy steel

The Alloying elements make the difference between Low alloy steel and high alloy steel.

Low alloy steels : in which Alloying elements are < 5%

High alloy steels :with more than Alloying elements > 5%

The demand for high strength, good weldability, and higher resistance to atmospheric corrosion is met by a group called the high-strength low-alloy (HSLA) steels. The HSLA steels have low carbon contents (0.05-0.25% C) in order to produce adequate formability and weldability, and they have manganese contents up to 2.0%. Small quantities of chromium, nickel, molybdenum, copper, nitrogen, vanadium, niobium, titanium and zirconium are used in various combinations. HSLA steels are used for oil or gas pipelines, ships, offshore structures, and storage tanks.

Stainless Steels is a high alloy steel which contains at least 10% chromium, with or without other elements. Based on the structures, stainless steels can be grouped into three grades:

Austenitic: Typically contains 18% chromium and 8% nickel and is widely known as 18-8. Nonmagnetic in annealed condition, this grade can only be hardened by cold working.

Ferritic: Contains very little nickel and either 17% chromium or 12% chromium with other elements such as aluminum or titanium. Always magnetic, this grade can be hardened only by cold working.

Martensitic: Typically contains 12% chromium and no nickel. This grade is magnetic and can be hardened by heat treatment.

Commonly used alloying elements are

- Chromium

- Nickel

- Molybdenum

- Manganese

- Vanadium

- Titanium

- Silicon

- Boron

- Aluminium, Cobalt and Tungsten

Use of Alloy Steel

Alloy steel can be used in process area where carbon steel has limitation such as

  • High-temperature services such as Alloy Steel Heater tubes or Alloy Steel Boiler Tubes
  • Low-temperature services such as Cryogenic application
  • Very High presser service such as Steam Header

Here you can see the common alloy steel grade that you will come across.

  • For Alloy Steel Pipes : ASTM A335 Gr P1, P5, P11, P9 Pipe suppliers
  • For Alloy Steel Wrought Fittings: ASTM A234 Gr.WP5, WP9, WP11 Pipe fittings suppliers
  • For Alloy Steel Forged Fittings: ASTM A182 F5, F9, F11 Fittings suppliers

These p5, WP5, and F5 are having similar chemistry so that they can weld together.
