SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the Q310GNH hot rolled steel angles, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel's mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of Q310GNH hot rolled steel angles, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of Q310GNH hot rolled steel angles steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.
