    can you laser cut carbon fiber

    Is this okay? Drop power (start ~300W), boost speed (try 8m/min), enable pulse (2000Hz/<50% duty) + max air assist (8Bar, nozzle close!) – kills charring/delamination/smoke.

    Corossion Fatigue

    The increase in surface roughness after corrosion depends on several factors, including the type of corrosion, the corrosive agent, the duration of corrosion, and the material properties. Generally, corrosion leads to an increase in surface roughness, with the specific percentage increase...

    Carbon Content

    According to the A515/A515M standard, the maximum allowable carbon content for Grade 70 plate is 0.35%, with no specified minimum carbon content. Although the carbon content of the plate is as low as approximately 0.049%, with other elements meeting the requirements, determining compliance with...

    How to work-harden Stainless Steel

    For 316 stainless steel, its yield strength is typically lower, around 200 MPa. To increase the yield strength of 316 stainless steel to at least 400 MPa, more complex treatment methods may be required, or another type of stainless steel may be a better choice. 301 stainless steel in the "1/2...

    Hard milling for tooling

    "440C stainless steel, while superior in hardness, is generally more difficult to machine, whereas 420 stainless steel typically offers better machinability due to its improved cutting performance and grindability. For applications like small split cavity molds, 420 stainless steel may be easier...

    How can you compare with metals' ductility and malleability?

    Maybe ,you should focus on several key properties: 1.Yield Strength: This is crucial to determine how much force the material can withstand before it begins to deform permanently. Inconel 625 typically has higher yield strength compared to stainless steel and carbon steel. 2.Work Hardening...
