Chemical Composition of 1.7225 Steel

The reliable performance of 1.7225 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:

• Carbon (C): 0.38 – 0.45%
• Chromium (Cr): 0.90 – 1.20%
• Molybdenum (Mo): 0.15 – 0.30%
• Manganese (Mn): 0.60 – 0.90%
• Silicon (Si): 0.10 – 0.40%

Functioning and Reasoning of Chemical Elements

• Chromium (Cr) & Molybdenum (Mo): This combination is the core of 1.7225 steel. Chromium enhances the steel’s hardenability and corrosion resistance. Molybdenum adds to its strength, toughness, and resistance to wear. Together, these elements give the steel the ability to be hardened uniformly through large sections.
• Manganese (Mn): Manganese increases the steel’s hardenability and tensile strength. It also helps to prevent hot shortness during hot working, ensuring the material can be easily formed.

Hardness, Properties, and Applications of 1.7225

Hardness

In its normalized or as-rolled condition, 1.7225 steel typically has a hardness of around 217 HB. It can be hardened and tempered to achieve a working hardness in the range of 28-32 HRC, or even higher depending on the application.

Properties

• High Strength & Toughness: It provides an excellent balance of these two properties, making it ideal for components that must withstand both high stress and impact.
• Good Fatigue Resistance: It holds up well under repeated stress cycles, which is critical for dynamic components.
• Excellent Machinability: In its annealed condition, it can be easily machined into complex shapes.
• Good Weldability: It can be welded using standard procedures, but pre- and post-weld heat treatments are recommended for critical applications to prevent cracking.

Applications

1.7225 alloy steel is a versatile grade used for a wide range of engineering and structural components. Key applications include:

• Shafts and Axles
• Gears and Pinions
• Connecting Rods
• Drill Collars
• Couplings and Spindles
• Bolts and Nuts for high-stress applications

1.7225 Steel FAQ Section

Q1: Is 1.7225 considered a tool steel?

A: No, 1.7225 is a medium carbon alloy steel, not a tool steel. While it can be used for some tooling applications, it lacks the high wear resistance of dedicated tool steels.

Q2: Can 1.7225 steel be used in high-temperature applications?

A: 1.7225 steel is primarily used for ambient and moderately elevated temperature applications. For hot work, a specific hot work steel would be required.

Q3: Is 1.7225 steel easy to weld?

A: 1.7225 steel can be welded, but due to its high hardenability, it is susceptible to cracking, so preheating and post-weld heat treatment are often necessary for
