Why does L19 material require special handling?
Like most high-strength quench and temper steels, L19 requires special care to avoid hydrogen embrittlement or stress corrosion. The material is easily contaminated and subject to stress corrosion. The parts must be kept well-oiled at all times and not exposed to moisture. Wearing gloves while handing L19 parts is a good precaution.
