Pressure Vessel Plate - Carbon Steel Plate

Mainly detecting the content of carbon, silicon, manganese, phosphorus, and sulfur. Some carbon steels also contain a certain amount of elements such as copper, chromium, nickel, molybdenum, vanadium, etc. Carbon is the main factor determining the strength of steel plates, that is, the strength of steel plates increases with the increase of carbon content. The carbon content of carbon steel plates ranges from 0.16 to 0.33%. Manganese and silicon also have the effect of improving materials and increasing strength. Silicon: 0.10-0.55%, manganese: 0.4-1.6%. Some standards do not require silicon or manganese for ordinary boiler plates, with copper below 0.30%. Other standards such as Japan and Russia do not have copper content requirements. Some high-quality steel products contain chromium (below 0.25%), nickel (below 0.30%), molybdenum (below 0.10%), and vanadium (below 0.03%). The chemical composition of each level of boiler steel plate is shown in the product standards provided in Table 6-7-3.
