Services For Fastener Testing
Testing Methods for Various Materials
Infinita Lab offers a wide range of fastener testing services for various metal fastener types. We have highly experienced personnel in materials engineering, metallographic testing, chemical analysis, materials testing, and metrology. Our fastener testing services are certified and carried out in accordance with NAS, NASM, SAE, ASTM, and other industry standards.
Metallographic Testing
Many macrostructure and microstructure analyses are carried out, including:
- Microscopic analysis
- Carburization of Grain Size or Decarburization
- Metal Plate Thickness
Furthermore available are surface contamination, alpha case, thread examination, microstructure, macro-etch, grain flow, and root cause failure analysis.
Mechanical Testing
Infinita Lab can identify your materials’ mechanical characteristics, including their hardness, load capacity, and fastener tensile strength.
- Hardness Evaluation
- Magnetic Transparency
- Shear Yield by two times Testing for Strength Wedge & Axial Tensile Proof Load
- Tension Tiredness test
- Strip Cone Test
- Flattening
- Testing the creep
- Test for Stress Rupture
- Stress durability and hydrogen embrittlement
- Testing of Washers
- No-Cost Height Test
- Test for Compression Interlocking
- Test for Locking Washers by Twist
Fasteners of all sizes can be tested using equipment, which includes tensile machines with capacities ranging from 100 to 600,000 lbs.
Chemical Analysis
Many chemical services are offered for element and impurity analysis, material composition disclosure, and material identification.
- Spectrometric ICP (ICP-AES, ICP-MS)
- AES Evaluation
- FTIR Evaluation
- Determination of Carbon, Sulfur, Nitrogen, Oxygen, and Hydrogen
- Identification of the Positive Material (PMI)
- Testing With Salt Spray
Testing Without Disruption: Tensile Strength
- Without compromising your fastening, we will locate surface-breaking discontinuities.
- Examination of Magnetic Particles
- Testing using Liquid Penetrant
- X-ray inspection and ultrasonic testing (Radiography)
Dialogue Inspection
Fastener features, such as: are subject to dimensional inspection in compliance with NAS, MS, and ANSI specifications.
.
- Threads inside
- outside threads
The metrology division’s inspectors use optical, Smartscope, and CMM inspection techniques. Because the Smartscope may be programmed for repeat measurements, an inspection of large-quantity orders is accurate and quick.
Error Analysis
To ascertain the underlying reason for failed fasteners, our materials engineers conduct in-depth failure studies. A Failure Analysis Report serves as a record of all work and outcomes for you.
