Weathering steel, often referred to as COR-TEN steel, is a remarkable material celebrated for its ability to form a protective, rust-like patina when exposed to the elements. This natural layer shields the steel from further corrosion, making it a top choice for outdoor applications such as bridges, buildings, and sculptures. While its durability and aesthetic … Read more
P-Numbers, A-Numbers, and F-Numbers in Welding In welding, efficiency, safety, and quality are paramount. To achieve these, welding professionals rely on standardized systems to classify materials, filler metals, and welding processes. Among the most critical classification systems are P-Numbers, A-Numbers, and F-Numbers. These numbering systems, primarily defined by the American Society of Mechanical Engineers (ASME), … Read more
Ferrite Percentage to Ferrite Number Calculator Understanding Ferrite Content: How to Convert Ferrite Percentage to Ferrite Number Ferrite content is a critical factor in stainless steel welding, influencing the weld’s resistance to corrosion, hot cracking, and embrittlement. Welders often need to measure or specify ferrite content, either as a ferrite percentage or a ferrite number … Read more
