AI Thread Summary
A2 Tool Steel can be heat treated to improve its strength, but achieving a yield strength of 700 MPa without plastic deformation may be challenging. The yield strength of A2 is typically around 1300 MPa, suggesting that it should theoretically withstand the required stress. However, tempering at higher temperatures, such as 100 degrees Celsius, does not significantly enhance its strength. Proper heat treatment methods must be carefully considered to meet specific performance requirements. Ultimately, achieving the desired mechanical properties will depend on the heat treatment process used.

Hi everyone,

I have a part that's made of A2 Tool Steel (unknown HRC). It needs to be able to withstand a bending force, stress of approx. 700 MPa, without plastically deforming. Is there a method to heat treat it to be able to withstand that stress?

TIA...

Isn't the yield strength of A2 tool steel like 1300MPa? This isn't enough?. Tempering it say 100 degrees more barely increases the strength.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
