Low Temperature Tensile Testing

Subodh Material Technologists provides low temperature and sub-zero temperature tensile testing of metals, steels, alloys and engineering materials from +25°C down to −196°C.

Our controlled low-temperature tensile testing capability allows mechanical properties to be evaluated under temperatures representative of demanding low-temperature and cryogenic service conditions.

Testing is performed using controlled specimen temperature, controlled loading conditions and monitored test parameters. Our facility provides temperature control of approximately ±1°C during applicable testing conditions.

What is Low Temperature Tensile Testing?

Low temperature tensile testing evaluates the mechanical behaviour of a material when subjected to tensile loading at temperatures below room temperature.

Material properties can change significantly at low temperatures. Depending on the material, reduced temperature may affect:

• Yield strength

• Tensile strength

• Ductility

• Elongation

• Reduction in area

• Fracture behaviour

• Deformation characteristics

Low-temperature tensile testing therefore helps determine whether a material is suitable for applications where it will experience sub-zero or cryogenic service conditions.

Sub-Zero Tensile Testing from +25°C to −196°C

Subodh Material Technologists provides low-temperature tensile testing across a wide temperature range from +25°C to −196°C. Subodh Labs

The testing system provides controlled specimen temperature and controlled loading conditions so that mechanical properties can be determined at the specified test temperature.

The required temperature is established according to the applicable material specification, test standard and customer requirement.

Low Temperature Tensile Testing as per ISO 6892-3

ISO 6892-3 specifies the method for tensile testing of metallic materials at low temperatures.

Our low-temperature tensile testing capability supports applicable requirements of ISO 6892-3 for determining tensile properties of metallic materials under specified low-temperature conditions. 

Testing parameters are established according to the applicable material standard and agreed test requirement.

Low Temperature Tensile Testing as per IS 1608 Part 3

Testing can also be performed according to applicable requirements of IS 1608 Part 3 for tensile testing of metallic materials at low temperatures. Subodh Labs

The applicable specimen dimensions, strain rate, temperature and evaluation requirements are determined according to the relevant standard and material specification.

Temperature Control During Testing

Accurate specimen temperature is critical during low-temperature tensile testing.

Our facility provides controlled temperature conditions with temperature maintained within approximately ±1°C during applicable testing. Subodh Labs

Controlled temperature helps ensure that the tensile properties measured are representative of the specified test temperature.

The testing setup provides:

• Controlled cooling

• Temperature monitoring

• Stable specimen mounting

• Controlled loading

• Temperature verification

• Continuous monitoring during the test

Mechanical Properties Evaluated

Depending on the applicable standard and material specification, low-temperature tensile testing can be used to determine:

Yield Strength

The stress at which the material begins to undergo the specified level of plastic deformation.

Ultimate Tensile Strength

The maximum tensile stress reached during the tensile test.

Elongation

The percentage increase in gauge length following tensile deformation.

Reduction in Area

The reduction in cross-sectional area of the specimen following fracture.

Other applicable tensile properties can be reported according to the selected test standard.

Materials for Low Temperature Tensile Testing

Low-temperature tensile testing may be required for a wide range of metallic materials, including:

• Carbon steels

• Low-alloy steels

• Stainless steels

• Duplex stainless steels

• Nickel alloys

• Aluminium alloys

• Engineering alloys

• Cryogenic-grade materials

• Welded materials

• Heat-treated materials

• Plates

• Bars

• Forgings

• Pipes and tubes

The suitability of the test method and temperature is determined according to the applicable material specification.

Low Temperature Testing of Welded Materials

Welded materials intended for low-temperature or cryogenic service may require evaluation of their tensile properties at the specified service temperature.

Testing can be performed on applicable welded specimens to evaluate:

• Weld tensile strength

• Yield strength

• Ductility

• Elongation

• Reduction in area

• Low-temperature mechanical performance

Low-temperature tensile testing can complement other weld qualification tests such as impact testing, hardness testing and metallographic examination.

Cryogenic Material Testing

Materials used in cryogenic environments can experience significant changes in mechanical behaviour at very low temperatures.

Low-temperature tensile testing can therefore support material evaluation for applications involving:

• LNG

• Cryogenic storage

• Cryogenic processing

• Low-temperature piping

• Pressure equipment

• Oil & Gas

• Petrochemical applications

• Marine applications

• Energy infrastructure

• Specialized engineering systems

Testing conditions should be selected according to the actual service temperature and applicable material specification.

Low Temperature Tensile Testing Equipment

Our low-temperature tensile testing setup incorporates a controlled temperature environment around the tensile specimen.

Key features include:

• Low-temperature capability down to −196°C

• Controlled specimen temperature

• Temperature monitoring

• Stable specimen mounting

• Controlled loading rate

• Tensile property measurement

• Applicable ISO and IS standard testing

The current facility information specifies a testing range of +25°C to −196°C with approximately ±1°C temperature control. 

Low Temperature Tensile Testing & Impact Testing

Tensile testing and Charpy impact testing provide different information about material behaviour at low temperature.

Tensile testing evaluates properties such as strength and ductility.

Charpy impact testing evaluates impact toughness and energy absorption.

For critical low-temperature applications, both tests may be required depending on the applicable material specification and project requirements.

Metallographic Evaluation After Low Temperature Testing

Where required, metallographic examination can complement low-temperature mechanical testing.

Metallography may be used to investigate:

• Microstructure

• Grain structure

• Phase characteristics

• Weld metal

• Heat affected zone

• Fracture-related features

• Heat-treatment effects

This provides additional information when investigating material behaviour under low-temperature conditions.

Our low-temperature tensile testing services can support:

• Oil & Gas

• LNG

• Cryogenic equipment

• Petrochemical

• Marine

• Power generation

• Pressure vessels

• Pipelines

• Structural engineering

• Aerospace

• Defence

• Research & Development

• Material qualification
