Chemical Analysis:
Optimum size is 1" x 1" x 1/2" of metallic material for analysis. Smaller sizes, chips, fines, drillings, etc. may require a melt preparation of at least 45 grams sample material weight (Kelmelt charge added).

Mechanical Properties:
Optimum sizes by test method are-

Tensiles:
Flats (sheet/ plate) 12" x12" x thickness (tube/ pipe) 8" length, minimum of 1" of diameter

Bar (round/ hex stock) 8" length

Finished Part Should have 6" of flat surface or enough stock to allow 0.252 diameter tensile

Full Size (tube/ pipe) 18" length, full diameter (wire) minimum 24" length (fasteners) as shipped

Charpy:
Enough stock per piece for (3) specimens - 1/2" x 1/2" x 2" each

Hardness:
Minimum 1" x 1" x thickness or actual part (or segment of part.)

Salt Spray/ Humidity:
Standard panels or actual as shipped piece(s)

Failure Analysis:
Actual failure section and/or assembly (if possible). Note: Do NOT clean the segment(s), ship as failed. Place in zip lock bag, if possible. Do not have mating faces touching during transit.

Tensile Testing Metallurgical Laboratory has many unique sample preparation techniques and processes. We can make and test a wide variety of sub-size, standard and macro size specimens.

All preparation and testing is performed in accordance with customer requirements utilizing the most current specification revisions (ASTM, AMS, ASME).

Please contact Cindy Tesmer, Ken Kasnyik, Jeff Smith, or Jim Bartholomew with any questions regarding sample size.
