Q295GNH steel chemical composition: C: 0.14～0.19, Si: ≤0.30, Mn: 1.00～1.30, P: ≤0.025, S: ≤0.025, Cr: 0.80～1.10 Q295GNH mechanical properties: Tensile strength σb (MPa): 880-1180 Yield strength σ0.2 (MPa): 635 Elongation δ5(%): 9 Reduction of area ψ(%): 35 Impact toughness value αku (J/cm2): 34

Large-thickness hot rolled 09CUPTIRE-A, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

Affected by the weak futures performance and weak spot follow-up, the steel billet price is temporarily stable. The overall growth trend of China's hot rolled 09CUPTIRE-A is slowing down, and the demand in the north is lower than that in the south. Under the background of economic recovery, the demand toughness still exists, the resource inventory is tight, and the actual willingness of the spot merchants to let the price is not obvious. The price of hot rolled 09CUPTIRE-A is expected to be adjusted and operated stably.
