Recently, our company has completed the production of a batch of S30408 stainless steel plates, which will be loaded and shipped to Indonesia. This customer from Indonesia is an old customer of ours. Due to construction needs, he purchased 100 tons of S30408 stainless steel plates from us.
In order to ensure that our customers can receive stainless steel plates that meet their requirements, we will conduct strict inspections on each batch of goods before shipment. The usual inspections include thickness testing, length measurement, chemical composition analysis and surface quality inspection.
S30408 material is equivalent to 06Cr19Ni10 material under our national standard (GB/T24511-2017), which is a commonly used stainless steel material. S30408 is the name of the material with material 304 and material serial number 08 in the UNS numbering system.
1. Chemical composition analysis
In order to ensure that the composition of the material meets international standards, we conduct a comprehensive spectral analysis. Chemical composition testing includes the detection of key elements such as chromium (Cr), nickel (Ni), carbon (C), and manganese (Mn) to ensure that the composition ratio is accurate.

2. Length measurement:
Use tools such as micrometers and tape measures to accurately measure the length of stainless steel plates.
3.Thickness test:
We used a high-precision thickness gauge to carefully inspect the thickness of each stainless steel plate. According to the S30408 standard, we ensure that the thickness of each plate is within the tolerance range to meet the customer's strict requirements for dimensional accuracy.
4. Surface quality inspection
Visually inspect or use a magnifying glass to observe the surface of the stainless steel plate to ensure that it has no scratches, cracks, rust, contamination or other surface defects.
After completing all inspections, we will immediately arrange for shipment. To ensure that the plates are not damaged during long-distance transportation, we use professional protective packaging materials and install protective film on each stainless steel plate. In addition, the goods are clearly marked, and each batch has a corresponding production number, test report and transportation information to ensure that customers can quickly check the products after receiving them.
