The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. RINA FH32 ship hulls steel plates Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.
A516 Gr65 steel is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard. A516 Gr65 plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. Our RINA FH32 ship hulls steel plates pressure vessel plate has good dimensional tolerance and surface quality.
The main applications of normalizing are as follows:① For low carbon steel, RINA FH32 ship hulls steel plates. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. RINA FH32 ship hulls steel plates, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.
