Metal Materials Mechanical Performance Testing

CTI metal materials mechanical performance testing can provide a series of tests to identify and test the service performance and process performance of metal material products. Through CTI Metal materials mechanical performance testing, it can help customers to evaluate the mechanical performance of materials and identify the weakness (service limit) of materials.

◉ Service Background

1. Through mechanical performance testing, we can master its service performance and achieve the best economy;

2. Mechanical performance is the main basis for the design and material selection of mechanical parts, which provides guidance for customers to optimize design and scheme;

3. Evaluate whether the materials meet the corresponding standard requirements and protect the interests of customers in trade;

4. Quality control of production process;

5. Research and development of new materials.

◉ Service Content

1. Test categories and items

Tensile test	Tensile strength, yield strength, specified plastic elongation strength, elongation, reduction of area, elastic modulus, N value, R value, Poisson's ratio (provide cross-sectional area of sample), etc.
Impact test	Absorbed energy, lateral expansion value, shear section rate
Bending test	After the bending test, observe whether there are cracks on the bending outer surface of the sample
Compression test	Compression strength
Test of pipe process performance	Flattening test, flaring test and curling test
Fastener performance test	Failure torque, hydrogen embrittlement test, tensile strength of screws and bolts,
Hardness test	Rockwell hardness, brinell hardness, vickers hardness and micro vickers hardness, knoop hardness and gradient hardness

2. Adaptive range of product

It is suitable for metal materials and their products, including:

Iron and steel materials: carbon steel, stainless steel, heat-resistant steel, alloy steel, cast iron, etc.

Non-ferrous metals: aluminum and aluminum alloys, copper and copper alloys, etc.

Special metal materials: functional alloys, metal matrix composites, etc.

Other metal products: profiles, plates, wires, pipes, fasteners, castings, auto parts, mechanical equipment and parts, etc.

3. Routine sample requirements

Tensile test	1. round bar sample: d≥10mm, length L≥200mm 2. Rectangular sample: ≥2*200mm(L minimum 120mm, for American standard L≥100mm) 3 Tubular specimen: L≥200mm for tube arc specimen, L≥300mm for whole tube specimen, and OD≤30mm, which can be stretched for whole tube
Impact test	Sample size: 55mm×10mm×10mm, pattern surface roughness (Ra) should be no more than 5um
Bending test	Strip specimen: thickness greater than 2mm, L≥150mm
Compression test	Ф20*80mm
Flattening test	Metal pipe with outer diameter ≤600mm and wall thickness ≤15%; 50mm≤ metal pipe length ≤100mm
Flaring test	Generally, L≥100mm is required, and it is estimated that L≥1.5OD will be used according to different changes of pipe outer diameter.
Curling test	OD≤100mm and t ≤ 10mm; Tube length L≥3D (minimum 1.5D)
Fastener performance test	3≤ screw diameter < ＜M39
Vickers and Micro Vickers Hardness, Knowles Hardness	Thickness is better than 0.5mm
Brinell hardness	The length, width and thickness of the sample are all greater than 10mm. It is suggested that the two parallel surfaces with surface roughness Ra not greater than 1.6μm should be quite parallel, and the larger the indentation diameter requires the thicker the sample.
Rockwell hardness	The thickness of the specimen is better than 3.3mm and the width is better than 5 mm. It is suggested that the surface roughness Ra of the specimen should not be greater than 1.6 μm.
