The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A514 grade K alloy steel plate is suitable for the length required by the construction of steel pipes.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In A514 grade K alloy steel plate, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
With our own engineers, metallurgists and CAD draftsmen, we can provide total support from design through to machined casting. OEM precision casting investment A514 grade K alloy steel plate casting auto parts, customized investment casting auto parts, custom precision casting automobile parts, truck casting iron fitting parts. Precision Casting: Tooling making → Wax pattern → Shall making → Chemical analysis → Pouring → Measurement & inspection → Heat Treatment → Processing → Finished product.
