Steel plate is flat-rolled steel delivered as individual plates (not coil) for fabrication where thickness stability, flatness, and verified mechanical properties must remain consistent through cutting, forming, welding, and inspection. In project packages, steel plate is often treated as a starting material for downstream manufacturing, where the process route and plate category can matter as […]

Differences of ASTM A53 B and ASTM A106 B. ASTM A53 B covers ERW, Seamless and Galvanized steel pipe. A106 B covers only seamless steel pipe for high temperature service.

Heat treatment methods for carbon and alloy steel pipe includes normalizing, annealing, tempering, quenching. It will improve the material performances.

BS EN 10204:2004 is British Standard that related to different types of inspection documents for steel metal products. There are 4 types for EN 102024, 2.1, 2.2, 3.1 and 3.2, the later two types are the mostly used in steel pipe and plates products, so here we will mainly introduce the major differences between two […]
