China made SA633 grade D carbon steel plate sheet price per kg

The main raw material of SA633 grade D carbon steel plate sheet, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.

The carbon content of No. 55 steel is 0.55%, and the heat treatment is mostly used for quenching and tempering. The carbon content of No. 55 steel is large, and the hardness after quenching is higher (about HRC63). SA633 grade D carbon steel plate sheet, High-quality carbon structural steel 55# is a high-strength medium-carbon steel with high surface hardness and strength after treatment, but poor plasticity and toughness, medium cutting performance, poor weldability and hardenability, and water quenching can form cracks propensity.

Management information and high efficiency. Because of the rapid flow of SA633 grade D carbon steel plate sheet goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

Flat SA633 grade D carbon steel plate sheet steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other SA633 grade D carbon steel plate sheet welding process requirements.
