Q550NH curtain wall steel material plate weight:
1) Theoretical weight of Q550NH curtain wall steel material plate:
The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate.
2) The actual weight of Q550NH curtain wall steel material plate:
The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. Q550NH curtain wall steel material, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of Q550NH curtain wall steel material, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

Most common Q550NH curtain wall steel material steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled Q550NH curtain wall steel material steel plates.

35SiMn steel chemical elements: C: 0.32-0.40, Si: 1.10-1.40, Mn: 1.10-1.40. The mechanical properties of 35SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 45; impact energy: 47J. 35SiMn steel belongs to alloy quenched and tempered steel with good properties and can be used instead of 40Cr steel. After quenching and tempering, Q550NH curtain wall steel material, 35SiMn steel has high static strength, fatigue strength, wear resistance, good toughness, good hardenability and medium plasticity during cold deformation.
