Titan Evo L19 Head stud kit Evo 7+ 7Bolt

19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.
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.
