Alloy steel specification, Standard and identification

Alloy Steel pipe contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous.

Q&A

Our team of experienced sales specialists proudly partners with gas and chemical processors, power generation plants, oil refineries, and related industries to offer piping components and value-added services.

The most important and desired changes in alloy steel are:

Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. These metals are added to produce specific properties that are not found in regular carbon steel. The elements are added in varying proportions (or combinations) making the material take on different aspects such as increased hardness, increased corrosion resistance, increased strength, improved formability (ductility); the weldability can also change.

  • Increased hardenability.
  • Increased corrosion resistance.
  • Retention of hardness and strength.

Nearly all alloy steels require heat treatment in order to bring out their best properties.

Alloying Elements & Their Effects

  • Chromium – Adds hardness. Increased toughness and wear resistance.
  • Cobalt – Used in making cutting tools; improved Hot Hardness (or Red Hardness).
  • Manganese – Increases surface hardness. Improves resistance to strain, hammering & shocks.
  • Molybdenum – Increases strength. Improves resistance to shock and heat.
  • Nickel – Increases strength & toughness. Improves corrosion resistance.
  • Tungsten – Adds hardness and improves grain structure. Provides improved heat resistance.
  • Vanadium – Increases strength, toughness and shock resistance. Improved corrosion resistance.
  • Chromium-Vanadium – Greatly improved tensile strength. It is hard but easy to bend and cut.
