9310 Alloy round steel

Alloy Steel Round Bar 9310 is normally used for aerospace, automotive, industrial, and machinery applications.     9310 Steel exhibits good strength, high toughness, hardenability, core strength, and very high fatigue strength.     Furthermore, this material is Vacuum Arc Remelted (VAR), providing a superior consistency throughout the material.

9310 is a premium quality alloy carburizing steel, containing nickel, chromium and molybdenum.  It has a high hardenability, high core hardness and high fatigue strength, all of which make it ideally suited for critical aircraft engine gears, automotive applications, structural components, gears, rods, heat-treatable shafts, high performance helicopter transmission gears, and other components.

Known as (Alloy Steel) 9310, this metal is a mix containing a composition of iron, nickel, chromium, and other elements in a carbon steel.    Its UNS designation is G93106.    It is one alloy steel in a group of many types which all have unique ratios to provide different properties and qualities for design.    This version is especially useful for a wide variety of parts in gears, engines, and other components on planes as well as other industries.    9310 is known to stand out for its high core hardness with great strength, toughness, and ductility.    Those properties on account of its balanced blended therefore make 9310 a material preferred for various aerospace and other engineering applications.    This alloyed steel in particular is excellent for clutch parts, piston pins, shafts, boring bars, and a variety of pinions which must function reliably in various crafts.

The chemistry of this alloy consists of Nickel (Ni), Chromium (Cr), Manganese (Mn), Silicon (Si), Phosphorus (P). Sulfur (S), Molybdenum (Mo), and Carbon (C). There are also specifications to percentage by weight of these elements such as Nickel (3.5%), Chromium (1 to 2%), Manganese (less than 1%), Silicon (less than 1%), Phosphorus (less than 1%).  Sulfur (less than 1%), Molybdenum (less than 1%), and Carbon (less than 1%).  9310 has a density of between 7.7 and 8.3 g/cm3 (or between 0.28 and 0.30 lb/in3).  It has a Rockwell C hardness of 22, a 17.30% elongation at break (in 50 mm), a shear modulus of 0 GPa (or 11600 ksi), and an elastic modulus of 190 to 210 GPa (or 27557 to 30458 ksi).  In addition, this alloy also has a yield strength of 450 MPa (or 65300 psi) and an ultimate tensile strength of 820 MPa (or 119000 psi).  It has a Poisson's ratio of 0.33 and a thermal expansion coefficient (at 20 degrees C or 68 degrees F) of 11.5 µm/m degree C or 6.39 µin/in degree F.
