It is expected that the price of low alloy steel plate q345 will remain stable

The steel such as low alloy steel plate q345 delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Mechanical properties of 45# high quality carbon structural steel: tensile strength σb (MPA): ≥ 600 (61), yield strength σs (MPA): ≥ 355 (36), elongation δ5 (%): ≥ 16, reduction of area ψ (%): ≥ 40, impact energy Akv (J): ≥ 39, impact toughness αkv (J / cm2): ≥ 49 (5), hardness: unheated ≤ 229HB; annealed steel ≤ 197HB. low alloy steel plate q345, 45# steel is used to manufacture parts with high strength requirements.

At present, there is no obvious release of market demand, the terminal is basically purchased on demand, and the transaction volume is not obvious. However, the current market inventory resources of low alloy steel plate q345 are relatively small, business sales pressure is not big, coupled with cost support, so the willingness to stand out is strong. However, after the continuous rise in the early stage, the market's fear of heights has increased, and the operation is still dominated by shipment, and the space for low alloy steel plate q345 price rise is limited. Overall, it is expected that low alloy steel plate q345 prices will be strong tomorrow.
