Metal Failure Analysis Services

GRG Test has accumulated many years of experience in the field of metal failure analysis and is familiar with the testing of various metal performance. Through comprehensive analysis and detection methods, we can analyze the failure causes of metal materials, which can provide scientific basis for improper design, material defects, casting defects, welding defects, heat treatment defects, etc. in scientific research and production; besides, we can also test the microstructure, mechanical properties and analyze the compositions of materials, and predict and monitor the use effect of products for you, thus providing basic basis for material selection and use.

Service Introduction

With the rapid development of industrial production, the requirements for the quality of metal components have got higher and higher, but early failure of products still occurs. Therefore, enterprises need to carry out failure analysis to find out the causes of failure, and put forward effective improvement measures to ensure the safe operation of projects.

Test Cycle:

10 to 15 working days, emergency services are available

Product Scope:

Metal-related products such as auto parts, precision components, mold manufacturing, casting, forging and welding, heat treatment and surface protection.

Test Items:

(I) Common failure modes:

Fracture (ductile fracture, brittle fracture, fatigue fracture, stress corrosion fracture, etc.)

Corrosion (chemical corrosion, electrochemical corrosion)

Others (wear, functional failure, etc.)

(II) Including but not limited to the following frequently tested items:

Test Items	Test Method and Standard	Sample Requirements
Fracture analysis	Internal standards	The fracture cannot be abraded
Average grain size of metal	Internal standards	/

Micrograph evaluation of non-metal inclusion	Internal standards	/

Metallographic analysis	Internal standards	/

Composition analysis	Direct-reading spectrometer, ICP, etc.	100g

Tensile property	ASTME8/E8M-13 ISO 6892-1998 GB/T 228.1-2010	1. Generally, the sample length shall be ≥ 200mm; ； 2. If the sample length is < 200mm, the samples of a smaller proportion can be adopted to test, which shall require the customer to confirm first;





Bending property	ASTM E290-2009 GB/T 232-2010 ISO 7438:2005	The width is ≥20mm, The length is related to the thickness and shall be greater than 200mm





Hardness	Brinell hardness, Rockwell hardness, Vickers hardness	Different hardnesses require different sizes, it should confirm specifically
Analysis of corrosion products and trace foreign matters on the surface	Adopt internal method	/

Failure recurrence/verification	Adopt internal method	Depend on the specific test items
