Steel plate base material (raw material) inspection is a crucial step in ensuring the quality and performance of steel products. This process involves a range of inspection methods, each with its own reference standards and key considerations. In this article, we will explore the advantages of steel plate base material (raw material) inspection, focusing specifically on the Q355B grade, and discussing various inspection techniques and their associated standards. Visual Inspection Firstly, let’s consider the visual inspection method. This involves a thorough examination of the steel plate’s surface for any visible defects or irregularities. Visual inspection is a quick and cost-effective way to identify potential issues, such as cracks, scratches, or discoloration. While it may not provide quantitative data, it serves as a valuable initial screening tool. Mechanical Testing Mechanical testing is another important aspect of steel plate base material (raw material) inspection. Tensile testing, for instance, measures the […]

Q235B and S235J0: Key Differences, Welding Considerations, Chinese Steel Mills’ Production and Advantages Q235B and S235J0 are two widely used structural steel grades, each with its unique characteristics and applications. Understanding the differences between these two grades, along with the production capabilities and advantages of Chinese steel mills, is crucial for making informed decisions in engineering projects. This article aims to delve into these distinctions, referencing their respective standards, highlighting welding considerations, and discussing the production and advantages of Chinese steel mills. Q235B and S235J0: Reference and Properties Q235B, according to the Chinese standard GB/T 700, is a carbon structural steel known for its strength and ductility. It is widely used in various structural applications in China and other Asian countries. On the other hand, S235J0, defined by the European Norm EN 10025, is a structural steel grade commonly found in European projects. Both grades have similar yield strengths but […]
Stainless Steel – Fabrication: An Insight into the Material and Key Considerations During Fabrication Stainless steel, known for its corrosion resistance and durability, is a crucial material in the fabrication industry. Its unique properties make it suitable for a wide range of applications, from industrial equipment to architectural structures. In this article, we will delve into the nature of stainless steel, explore its fabrication process, and highlight the key considerations during the process. What is Stainless Steel? Stainless steel is an alloy of iron with a minimum of 10.5% chromium. The chromium content forms a thin, invisible, corrosion-resistant layer on the steel’s surface, protecting it from oxidizing and rusting. In addition to chromium, stainless steel may also contain other elements such as nickel, molybdenum, titanium, and nitrogen, which further enhance its properties. Stainless steel is classified into several types based on its composition and properties. The most common types include […]
