The company received new orders from Peru customer for more than 900 tons of ASTM A36 steel plates sa573 gr 65 carbon-manganese-silicon steel plates. These A36 steel plates will be used in the "Belt and Road" project - a mining conveyor project in Peru. This is our long-cooperated customer, who purchased thousand tons of A36 steel plates from us every year. And make our sa573 gr 65 carbon-manganese-silicon steel plates A36 steel plates well known in local.
The common delivery status of sa573 gr 65 carbon-manganese-silicon steel plates, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. sa573 gr 65 carbon-manganese-silicon steel plates, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265.
