Sustained-load cracking – which types of cylinders are most susceptible to SLC-related ruptures?

  • Any type of cylinder manufactured from 6351 alloy could conceivably develop a sustained-load crack over time if subjected to certain conditions.
  • However, a cylinder is more likely to rupture in applications where pressure is higher and where overfilling and abuse occur more often.
  • Historically, the applications most susceptible to SLC-related rupture are scuba and SCBA (life support).
