Carbon steel plates are generally defined as flat steel products with carbon as the principal alloying element and only limited amounts of other alloying elements. The main controlled elements typically include carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si), while other elements such as aluminum (Al), chromium (Cr), nickel (Ni), molybdenum (Mo), […]

API 650 is the principal standard for welded, vertical, cylindrical aboveground tanks used to store oil and other liquids at approximately atmospheric pressure. It establishes requirements for tank materials, shell and bottom design, welding, inspection, testing, and fabrication documentation. Its general provisions apply to non-refrigerated service at design temperatures up to 93°C (200°F), while Annex […]

As we know steel pipe and steel plate mechanical performances depends on two aspects: One is the heat treatment type; Another one also the most important factor is the chemical elements effect to these steel material. Common chemical elements in steel pipes and steel plates Common chemical elements in steel is C, Mn, S, P, […]
