Chrome Moly Tubing


Chrome Moly Tubing is High Quality Mechanical Steel tubing, which is in Form of Cold Drawn. Crome-Moly Tubing is manufactured under MIL-T- 6736 B (AMS-T-6736A), AMS-6371 and AMS-6360 standards. These tubing are heat treatable, though Hardenable easily machined. Tensile strength after heat treatment 860 N/mm2. Welded areas require heat treatment after welding to retain strength. Chrome Moly tubing are also known as Alloy tubing. General Abbreviations of chrome moly tubing are chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY ASTM A213 are often called as chrome moly tubing because of the chemical contain of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel and Chromium (or chrome) is the essential constituent of stainless steel. The composition chrome moly alloy steel Tubing 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. Advantages:

  • Consistent Workability
  • Preferred Fabrication
  • Higher than Standard Mechanical Properties
  • Indian Drawn 4130 steel tubing

Chrome moly pipe under ASTM & ASME specification A/SA 213 T1, T2, T11, T12, T15, T22, T91, T92, T122 are used for power industries whereas ASTM/ASME A/SA 213 T5, T9 are used for petrochemical industries
