Sustained-load cracking – how quickly do the cracks grow?

Very slowly, as extensive research by Luxfer and outside laboratories has shown.
No scientific evidence supports rumors and claims of “fast crack growth.”
Cracks typically take eight or more years to grow large enough to cause a cylinder leak.
Because SLC growth is so slow, properly trained inspectors have adequate opportunity to detect cracks during the normal requalification process.
