Testing Capabilities

Please review the optimum test sample size/condition section of each test listed below.  We are able to obtain several different tests from one sample. 
Please contact us for further details.

ALL SAMPLES MUST HAVE LONGITUDINAL ROLLING DIRECTION CLEARLY MARKED

Testing is performed utilizing optical emission spectroscopy equipment that provides the following elements:

STEEL (CARBON, ALLOYS, TOOL STEELS, CAST IRON):
     C, Mn, P, S, Si, Cu, Ni, Cr, Mo, V, Al, Nb, Ti, B, Ca

STAINLESS:
     C, Mn, P, S, Si, Cu, Ni, Cr, Mo

ALUMINUM (ALLOYS):
     Mn, P, Si, Cu, Ni, Cr, V, Ti, B, Ca, Mg, Zn, Pb, Ga

We are capable of testing small parts and small diameter wire

(*Optimum test sample size/condition: 3" x 3" or larger with flat, clean surface )

Tests are performed to ASTM, JIS, or DIN standards. We also offer BAKE HARDENABLE testing.
Test reports include (where applicable): Yield, Tensile, Elongation, n-value, r-value, YPE and Rockwell hardness.

*Optimum test sample size/condition:

Sheet: 12" x 12" (flat, unmarred sample with clean edges)
Tube: 12" minimum in length
Finished or formed part: Please contact us for details.

Tests performed to scales: HRBW - HRC - HRFW - Superficial (HR45TW - HR30TW - HR15TW)

(*Optimum test sample size/condition: 4" x 4" or larger with flat, clean surface )

Testing on Zinc or Aluminum Coated material is performed using the Weigh-Strip-Weigh method.

(*Optimum test sample size/condition: 6" x 6" or larger with flat, clean surface )

Measurement of the surface irregularities in the surface texture reporting Peak and Ra.

(*Optimum test sample size/condition: 6" x 6" or larger with flat, clean surface )

Evaluation of the ductility of sheet materials.

(*Optimum test sample size/condition: 12" x 12" or larger with flat, clean surface )

Quantifies the coating adhesion to the steel. Coating loss is determined by visual comparisons to designated charts.

(*Optimum test sample size/condition: 12" x 12" or larger with flat, clean surface )

Determines whether the metal has sufficient ductility to withstand bending without fracturing.  This test can also be used to determine whether the coating has sufficient adhesion to withstand bending without flaking or peeling.

(*Optimum test sample size/condition: 12" x 12" or larger with flat, clean surface )

Metallographic Testing

Case DepthDecarburized Gear ToothNon-metallic InclusionsSurface Discontinuity
Hot RolledGrain SizeFracture Surface
Section, Mount, and Polish
Metallographic preparation of a specimen for micrography.  The process involves: sectioning of the specimen in the area of interest to fit in a mount of a certain size, molding the specimen in a mounting medium, rough grinding the mounted specimen to obtain a plane surface, and fine polishing to a mirror-like finish for viewing at very high magnifications.  A chemical etchant is typically applied to reveal microstructural characteristics.
Micrography
An inverted microscope is used to view mounted and polished specimens at very high magnifications.  This is done to analyze such things as: microstructures, grain size, non-metallic inclusion content, surface discontinuities, case depth, and depth of decarburization.  Micrography is typically used as part of failure analysis.
Macrography
Visual and low magnification observations are made to examine specimens for such things as: surface conditions, fracture surfaces (fracture modes), small markings, and thread inspection.  Macrography is typically used as part of failure analysis.
Failure Analysis
Failure analysis uses metallurgical techniques to determine the causes of part and material failures.  This process can involve all of the testing described above.
Technical Report
A technical report is typically associated with a failure analysis process.  It details the steps performed and routinely includes several photographs.  A technical report includes a conclusion detailing the findings.
