Stress corrosion cracking tests
– Static : 3 or 4 points bending device, Constant load tensile tests, C-ring device tests and other loading methods such as U-bends
– Dynamic : slow-strain-rate tensile tests
ASTM G30, G36, G38, G39, G40 standards
Corrosion fatigue tests
– Rotary bending
– 4PB fatigue test
All tests can be performed under H2S pressure.
Corrosion fatigue tests in seawater
Hydraulic assist power machines with capacity of +/- 25kN, tensile-compression equipped with a 4 points bending device with a capacity of 10kN. Titanium chambers for chloride-containing media, temperature from 15°C to 80°C, dissolved oxygen control from low to saturated values, possibility to polarize specimens.
Corrosion fatigue tests in corrosive atmosphere
A unique tool enabling fatigue cycles in an accelerated corrosion test!
Performances : 0-15 kN ; 0-5 Hz, with or without cycle
Hydrogen embrittlement tests for the automotive industry
Mechanical testing at constant load, incremental step load or on pre-stressed specimens in corrosive environments (atmospheric or immersion) or under hydrogen charging to assess the sensitivity to hydrogen embrittlement of very high strength steels. Possibility of measuring hydrogen concentrations and determining its activity.
VDA standards: 238-201, 238-202, 238-203
