 Supply specifications: 

 Thickness of 4.5mm-100mm, width 1500mm-4020mm, length 3000mm-18000mm, the largest single steel weighing 25 tons. Can also be negotiated custom processing non-standard goods cut to length steel plate. 

 Origin: Anshan Iron and Steel, Wuyang Iron and Steel, Wuhan Iron and Steel, Baosteel, the new steel and other 

 Steel surface hardness: 

 Hot-rolled: ≤ 255HB; 

 The direction of the flaw detection and thickness of the performance: 

 Can produce additional testing requirements and Z15-Z35 tear-resistant steel plate (thickness direction performance), in accordance with standards such as ASTM, A770 steel plate Z to performance. 

 Chemical composition (%): 

 C :0.47-0 .54; si :0.17-0 .37; Mn :0.50-0 .80; Cr :0.80-1 .10; Ni: ≤ 0.03; V :0.10-0 .20; P: ≤ 0.025; S: ≤ 0.025; Cu: ≤ 0.025. 

 Uses and characteristics: 

 Compared with silicon, when the plastic is similar, with a high tensile strength and yield of steel hardenability, temper brittleness. To withstand high stress and temperature 300-350 ℃ about spring. Such as the governor spring, automotive machine steam seal springs, butterfly springs of high pressure water pump, condenser support spring and crusher spring. 

 Delivery status: 

 Normalizing and tempering, tempering, debugging, controlled rolling and cooling
