Ding Testing Inspection: Carbon/Sulfur Element Analysis, Ensuring the Quality Foundation of Industrial Materials

Carbon/Sulfur element analysis is a crucial material analysis technique used to accurately determine the carbon and sulfur content in metal materials, which is essential for ensuring material performance and quality control. Ding Testing Inspection's carbon/sulfur element analysis precisely controls the carbon and sulfur content in metal materials, safeguarding the high standards of industrial manufacturing quality.

Service Introduction

Carbon/Sulfur element analysis involves qualitative and quantitative analysis of the tested material to determine the presence of C/S elements and the content of each element, assessing whether they meet standard requirements. Carbon plays a significant role in the properties of steel; as carbon content increases, the hardness and strength of steel increase, while its toughness and plasticity decrease. Conversely, as carbon content decreases, hardness and strength decrease, while toughness and plasticity increase. Carbon/sulfur analysis instruments are a common type of measuring instrument in enterprise physical and chemical analysis rooms, used for quantitative analysis of carbon and sulfur element content in metals and non-metals.

Industry Pain Points

- Ensuring the precise determination of carbon and sulfur content in metal materials
- Assessing the impact of these elements on the performance of metal materials
- Evaluating the performance of metal materials under specific environmental conditions

Service Scope

Ding Testing Inspection's service scope is extensive, covering carbon/sulfur element analysis, including but not limited to:
- Determining the presence of C/S elements and the content of each element in the sample
- Judging whether the sample meets standard requirements
- Providing quantitative analysis of carbon and sulfur element content in metals and non-metals

Sampling Requirements

- Surface oil, dirt, oxides, coatings, plating, phosphating layers, and carburized nitride layers should all be cleaned with a grinding wheel or sandpaper before being made into shavings or small pieces (each piece less than 0.3g).
- Block samples: Discard the surface and take the internal material as the test sample. Harder materials can be cut into 2-3mm thick slices with a wire saw, then cleaned with a sand belt or grinding wheel, and cut into pieces.
- Sheet samples: Clean the surface and cut into small pieces.
- Thin tube samples: Flatten the tube, hammer it flat, clean the surface with a sand belt or grinding wheel, and then cut into small pieces. Alternatively, flatten the tube, grind both sides with a grinding wheel to make two flat pieces, then clean and cut into pieces.
- Wire samples: Straighten, clean the surface with a sand belt or grinding wheel, and cut into pieces.
- Cast iron samples: Take internal samples for testing to avoid surface sampling. Smaller samples are usually milled to remove 1-2mm from the surface, while larger block samples can be sawed to remove 2-3mm slices from the interior, cleaned with a sand belt or grinding wheel, and cut into pieces.
