Is silk fibre as strong as steel thread?

Silk fiber is known for its remarkable tensile strength, which can be comparable to that of steel thread when considering weight. However, steel is generally stronger on a per-weight basis, meaning that while silk can be incredibly strong relative to its size, it does not match the overall strength of steel in practical applications. In specific contexts, such as in the production of lightweight and flexible materials, silk's strength is impressive, but it cannot replace steel in structural uses.
