Mechanical Lab In Cleveland, OH

Tensile Testing:

Our specialty. Round tensiles include the basic sizes of .500, .350, & .250 on metallic or non-metallic materials. We can also machine subsize to about 3/4” in length, hardness range to 55 HRC, and test from room temperature to 1600°F. Flat tensiles are Waterjet cut which is a fast, effective method that does not compromise metals commonly affected by heat sensitivity. Typically the standard size (.500″) is fabricated per ASTM E8, ASTM A370 (steel), or ASTM B557 (aluminum) from the raw material. Other specimen configurations (.750, .250″, DIN, JIS, 80mm, etc.) are utilized. Samples can be pulled up to 400K.

Fastener Testing:

Includes two specialty tests: Rotational Capacity (Rocaps) to 2” diameter and Stress Durability (Hydrogen Embrittlement). Other routine tests performed to common test methods (ASTM, SAE, ISO, IFI, NASM, DIN, etc.) comprise of: Wedge/Axial Tensile, Proofload, Cone Strip, Shear (Single or Double), Torque Test, Drive Test, 24 Hour Heat Treat w/Hardness, Decarb, Grain Size, Salt Spray, and Chemistry (OES & Leco). TTML can perform tests up to a 2 1/2″ (64 mm) bolt.

Charpy Tests:

A charpy test includes 3 coupons which measure Energy in ft-lbs or Joules as needed. Test temperature is important factor. Tensile Testing’s can test from +212 to -320°F (+100 to -195°C)

Tubes and Pipes:

Full section or machine and test. Other testing includes: Flattening, Flaring, Reverse Flattening, and Crush

Fracture Toughness:

We can test to ASTM E399. The Fracture block is notched with a slot ending in drilled hole, (Chevron or Straight through Notches available), measured, pre-cracked, and tested. The value is denoted as KIC or KQ and is expressed in the units of ksi√in or MPa√m.

Bend Test:

Guided Bend, Semi-Guided Bend, Free Bend, Bend and Flatten, and the Wrap Around. Some of the bend test methods utilized include ASTM E190 and E290, ASME Section IX, and AWS D1.1. Adhesion or Coating Bends are also performed.

Customer Testing Capabilities

Properties evaluated include proofload, breaking strength, shear, compression, loading strength, torsional, bending, hardness, etc. Sample materials previously tested include: buckles, shackles, eyebolts, tiedowns, ramps, hitches, ropes, hooks, chains, etc.

400,00 lbs Capacity:

Tensile Testing can test the following products: Cable, Cargo Rings, Chains, Clevises, Eyebolts, Fasteners, Full Thickness Plate, Hoist Rings, Rebar, Shackles, Tow Hooks, Tubes, Turnbuckles, Wire TTML can perform tests up to a 2 1/2″ (64 mm) bolt.

Hardness:

Brinell (HB) (ASTM E10) Brinell Testing includes the Portable King Tester which allows testing large samples in-house or at your facility.

Rockwell (HR) (ASTM E18) The Rockwell Scales include: HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK
Superficial scales used when material is very thin include: HR15T, HR30T, HR45T, HR15N, HR30N, HR45N
Knoop (HK) (ASTM E384) Applied forces range from 1 to 1000 gf
Vickers (HV) (ASTM E92) Applied forces range from 10 gf to 30 kgf

Hydrogen Embrittlement:

Tensile Testing Metallurgical Laboratory tests notch bars (1a.1 or 1a.2) in accordance with ASTM F519 that have been plated or phosphated by hanging for 200 hours or until they break. We also supply the test bars. Other tests performed to verify hydrogen embrittlement are:
Stress Durability on Fasteners
Leco Hydrogen (Chemistry)

Cup Testing:

Two of the common Cup tests are the Olsen Cup test which is conducted on metallic sheet materials with thicknesses up to 0.125″ intended for forming applications, and sthe Erichsen Cup test which is used in Europe. The main differences between the two are the diameters of the penetrator and the dies.

Stress Rupture:

There are 3 types of test specimens we fabricate that are typically used: Smooth Bar, Notch Bar, Combination (Smooth & Notch) Bar. We also make specimens for Creep testing.
Three common test methods used for Stress Rupture are: USCAR 7 Deembrittlement Verification Test, ASTM F606, and NASM 1312-5.

Surface Roughness/Finish:

Tensile Testing uses the contact method (ASME B46.1) for Surface Roughness or Surface Finish where an instrument called a profilometer is used to drag a measurement stylus across the surface to determine the most common profile roughness parameter, Ra.

Weld Testing:

Tensile Testing routinely performs tests on welded plates and tubes in accordance with ASME & AWS for Procedure Qualification Record (PQR) and Welding Procedure Specifications (WPS).
Common Tests on welds: Tensile Tests, Bend Tests, PQR, Charpy Tests, Macro Etch, Penetration, Hardness Surveys, Post Weld Heat Treat
If NDT work is needed prior to cutting the plate, Tensile Testing has strategic partnerships with local accredited NDT labs for X-Ray (RT), Ultrasonic Testing (UT), Magnetic Particle (MT), and Visual Inspection (VT) that allows us to expedite your testing.
