In order to improve its mechanical properties, steel is alloyed with a variety of elements in total amounts of 1.0% to 50% by weight to produce alloy steel. Alloy Steel, in addition to carbon, also contains substantial amounts of elements like nickel, tungsten, molybdenum, chromium, silicon, manganese, vanadium and small quantities of a few commonly used elements such as sulphur, silicon and phosphorous. The addition of these alloying elements complements the steel with increased strength, chemical resistance and hardness. Trio Steel is a leading brand in the market of Steel products and exports and one of our known products include ASTM A691 GRADE 91 Alloy Steel Pipe. The most useful properties of ASTM A691 GRADE 91 Alloy Steel Pipe, which make them efficient include features like enhanced strength, toughness, hardness, hardenability, wear resistance, corrosion resistance and hot hardness and our product has been manufactured to provide them all. Certification: ISO 9001, ISO 14001 & OHSAS 18001
Trio Steel is a leading manufacturer, stockiest and exporter of ASTM A691 GRADE 91 Alloy Steel Pipe and it’s many variants.
