The main varieties of hot-rolled steel plates are ordinary carbon steel, low alloy steel, container plate, weathering steel, pipeline steel, hot-rolled steel strip for automobiles, ship plate, gas cylinder steel, boiler and pressure vessel plate, Q235NH steel structure. Hot-rolled steel strips are processed into different finishing lines to become steel plate, flat coil and slit steel strip products. Our hot-rolled steel plates are widely used in automobiles, machinery, ships, bridges, construction, pressure vessels, pipeline transportation, automotive industry.

The price of common carbon plate is relatively low compared with other kinds of steel Q235NH steel structure, and it can be used in a wide range of occasions, such as construction, machinery manufacturing, etc. Therefore, carbon plate is favored by users all over the world. And because of its large demand, fast circulation, the steel suppliers and exporters would like to keep huge carbon plate stocks, and thus the delivery is very quick. We also have large quantity stock for carbon plates. And we provide further processing for the carbon plate.

Hydrogen (H) is the most harmful element in general steel such as Q235NH steel structure. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
