Val-Met has the capability to carry out Material   testing  to meet & qualify  the requirements. Some of the tests being carried out in association with NABL approved laboratories,

(A) DESTRUCTIVE TESTING 

(B) NON- DESTRUCTIVE TESTING

(A) Destructive Testing

  •  Mechanical Testing 

(a) Tensile test at room temperature(ASTM E8M)

(b) Tensile test at elevated temperature(same)

(c) Stress rupture test in elevated temperature

(d) Bend Test(ASTM E8M)

 (B)  NON- DESTRUCTIVE TESTING

With qualified and experienced inspectors (ASNT qualified), the following non-destructive tests can be done in-house. 

  • Ultrasonic Test

Test Method: Pulse echo contact method.

Instrument: Ultrasonic Flaw Detector, calibrated.

Probes: Dual Crystal probes and special probes.

Specifications: AMS 2630B/2632 and ASTM Standards

                              Size: Above 12.5mm(0.5inch)

Reference blocks:  Manufactured in-house (1.2 mm FBH, 2 mm FBH etc) Flat Bottom Hole

The testing is done in-house with ASNT Level - II qualified inspectors for Plates, Rods, Forgings and Castings. 

Acceptance: Class AA, Class A

  •  Liquid Dye Penetrant Test.

The testing can be done in-house with ASNT Level - II qualified inspectors for primary product forms, Castings, Forgings and Machined Components.
