Alloy steel grades are carefully selected to fit any customer-specified application since they do differ in featured properties and strength.
Different alloy steel products are made out of a variety of alloy steel grades. Many industrial manufacturers and engineers mainly use these metals since they do fit for a lot of uses in various major industries like aerospace, automotive, and other machinery.
Alloy steel grades are mostly tempered and quenched to achieve toughness and high strength.
Forte Precision Metals does provide a unique information about each alloy steel grades and their specification when it comes to their nature, capacity, and suited applications.
Please see the alloy steel grades table below.
|4120||has good tough strength properties||used for forging applications as forged valve bodies and pumps|
|4125||a chromium-molybdenum alloy steel, displays good strength and toughness properties||automotive and engineering gear, engine construction – steering knuckles, forged crankshafts, etc.|
|4130||readily machineable, weldable and ductile, has tough strength||commercial and military aircraft, machine tools, automotive, hydraulic tools, aerospace, auto racing|
|4135||low-alloy steel, capable of being heat treated and has reasonable toughness||forged shafts, fixtures, collars, jigs, spindles|
|4140||provides good hardness penetration, wear resistant, tough and ductile||highly stressed parts, or components subjected to severe wear|
|4142||medium-carbon steel, readily heated and has tough strength||die holders, forged gears, collets, spindles, arbors, flanges, axles, clutch parts, etc.|
|4145||a chromium-molybdenum low alloy steel, readily forged, welded, and machined||drill collars, shafts, forged gears, rolls for paper mills, tool holders, and pump shafts|
|4150||low-alloy steel, has good atmospheric corrosion resistance and strength||forgings in the aerospace, gas, and oil industries, forged gears, shafts, and spindles|
|4340||nickel-chromium molybdenum alloy, has high toughness and fatigue strength||commercial and military aircraft, machine tool applications, automotive systems, forged steel crankshafts|
|52100||high carbon, chromium alloy steel||for highly stressed parts like aircraft bearing|
|6150||fine grained carbon-chromium alloy steel, highly abrasion resistant||gear and engine construction, forged crankshafts, connecting rods, pump and gear shafts, spindles and steering knuckles|
|8620||most widely used carburizing alloy, has high core strength||forged camshafts, gears, and fasteners|
|8740||nickel-chromium low alloy steel, has tough strength properties||high-strength forged fasteners|
|9310||low alloy steel, has good hardenability and fatigue strength||crankshafts, heavy-duty gear shafts, gears in truck and aircraft construction|
