In summary, 17-4ph h900 and hardened D2 tool steel have different properties, but 17-4ph h900 is known for its high strength and toughness, potentially making it more resistant to snapping. Heat treatment processes can further increase its resistance to snapping, and the shape and geometry of the material can also play a role. In certain applications, such as aerospace and defense, 17-4ph h900 may be a better choice than hardened D2 tool steel for its high strength and toughness.

Continually breaking a 0.236 dia. pin wrench, tightening a threaded collet-closer in high speed production application. Both ends of 1/2" D2 tool steel, turned down to create pin wrench, one end is bent at 60 degree angle, to allow an awkward reach sometimes necessary. D2 TS is then hardened & tempered. The 0.236 pins snap. Believe using 17-4 ph stainless steel, h900 would eliminate snapping. Can anyone comment?

Related to Would 17-4ph h900 resist snapping better that harded D2 TS?

1. Would 17-4ph h900 be more resistant to snapping compared to hardened D2 tool steel?

It is difficult to make a direct comparison between these two materials as they have different properties. However, 17-4ph h900 is known for its high strength and toughness, which can make it more resistant to snapping than hardened D2 tool steel.

2. Is 17-4ph h900 stronger than hardened D2 tool steel?

Both 17-4ph h900 and hardened D2 tool steel have high strength, but the strength of 17-4ph h900 can vary depending on the heat treatment process. In general, 17-4ph h900 is considered to have a higher strength than hardened D2 tool steel.

3. Can 17-4ph h900 be heat treated to increase its resistance to snapping?

Yes, 17-4ph h900 can undergo heat treatment processes such as precipitation hardening or aging to further increase its strength and toughness, making it more resistant to snapping.

4. Are there any other factors that can affect the snapping resistance of 17-4ph h900 and hardened D2 tool steel?

Yes, the shape and geometry of the material can also play a role in its resistance to snapping. For example, materials with sharp corners or edges may be more susceptible to snapping compared to those with rounded edges.

5. Are there any specific applications where 17-4ph h900 would be a better choice than hardened D2 tool steel in terms of snapping resistance?

It ultimately depends on the specific requirements and conditions of the application. However, 17-4ph h900 is commonly used in aerospace and defense industries for its high strength and toughness, making it a suitable choice for applications where resistance to snapping is crucial.
