What‘s The Feature Of Stainless Steel Rod/Bar?

One of the primary advantages of stainless steel bars is their excellent corrosion resistance. Stainless steel contains a minimum of 10.5% chromium, which forms a passive oxide layer on the surface, protecting it from corrosion and making it resistant to oxidation, rust, and staining. This corrosion resistance allows stainless steel bars to withstand exposure to a wide range of corrosive environments, including acids, alkaline solutions, saltwater, and atmospheric conditions.

Stainless steel bars exhibit high strength and durability, making them suitable for applications requiring structural integrity and load-bearing capacity. The addition of alloying elements such as nickel, molybdenum, and titanium enhances the strength and toughness of stainless steel bars, enabling them to withstand heavy loads, impact, and harsh operating conditions.

Stainless steel bars offer excellent heat resistance, allowing them to maintain their mechanical properties and structural integrity even at high temperatures. They can withstand both high and low temperature extremes without significant deformation, scaling, or loss of strength, making them suitable for applications involving heat treatment, elevated temperatures, and thermal cycles.

What Services Does Gnee Provide?

Gnee can provide the following measurement services for stainless steel:

Dimensional Measurement: Measure dimensional parameters such as length, width and thickness by measuring instruments to ensure that the stainless steel is qualified and meets the design requirements.
Surface Measurement: Measure parameters such as flatness, bumpiness and surface roughness of the stainless steel surface to help ensure that the quality and surface condition of the stainless steel meets the requirements.
Thickness Measurement: Use thickness gauges to accurately measure the thickness of the stainless steel to ensure it meets the design requirements.
Material Measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the stainless steel to ensure that the quality and properties of the stainless steel meet the requirements.

Gnee stainless steel can provide testing and the following third-party inspection services. These third-party testing services provide independent and objective verification of stainless steel’s compliance with relevant standards and regulations.

Mechanical Property Testing: Used to determine whether the strength, toughness, ductility and other mechanical properties of stainless steel meet the specified requirements.
Chemical Composition Analysis: Quantitative determination of elements on stainless steel samples through spectral analysis, atomic absorption spectroscopy, inductive coupling and other technologies.
Corrosion Performance Test: Common corrosion performance test methods include salt spray corrosion test, acid-base corrosion test and electrochemical corrosion test.
Tensile Strength Test: Through the tensile test, the parameters such as yield strength, tensile strength and breaking strength of stainless steel during the tensile process are measured.
Non-Destructive Testing: Non-destructive testing is used to evaluate hidden defects, cracks and looseness in stainless steel materials. Common methods include ultrasonic testing, magnetic particle testing, eddy current testing, and radiographic testing.
Pressure Test: By exposing stainless steel products to a specific pressure, it is tested whether there are problems such as leakage or deformation to ensure that its pressure resistance meets the requirements.
Surface Quality Test: Used to evaluate the surface flatness, smoothness and oxide layer of stainless steel products.
Welding Performance Test: Check the appearance, mechanical properties and metallographic microstructure of the weld to ensure that the quality of the stainless steel welded joint meets the requirements.
Metallographic Inspection: Through metallographic inspection, the structure, grain size, non-metallic inclusions, etc. of stainless steel are checked to evaluate its quality and performance.
