The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the SPA-H welded weathering steel sheet production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.
Common specifications for cold-rolled plates: thickness 0.2-4mm, width 600-2000mm, length 1000-6000mm.Commonly used grades: Q19-Q23, Q19F-Q23F, Q29(B)-Q345 A(B); SPCC, SPCD, SPCE, DC01-06.Because rolling at room temperature does not produce iron scale, the cold-rolled sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical and technological properties are better than hot-rolled thin steel sheets SPA-H welded weathering steel sheet. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets."
Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate SPA-H welded weathering steel sheet should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.
The ability to resist plastic deformation and fracture under the action of external load is called SPA-H welded weathering steel sheet strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.
