Round steel is a widely used metal material, mainly made of carbon structural steel. It usually has a circular cross-section, and can be made into materials of different shapes, such as cylinders, square columns, hexagonal columns, etc., through different processing methods during processing. According to the production process classification: divided into three types: hot rolling, forging and cold drawing; Hot-rolled round steel: the metal billet is passed through the gap (various shapes) of a pair of rotating rollers, and the

As an important material in shipbuilding and repair, marine steel plates have unique characteristics and advantages. Its high strength, corrosion resistance, good plasticity and weldability make it an indispensable material in the shipping industry. The characteristics of marine steel plates will be introduced in detail below. First, marine steel plates have high strength. As ships are subjected to huge winds and waves and complex water environments in the sea, the hull needs to withstand huge forces and impacts. Therefore, marine

Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly blunt edges. Flat steel can be finished steel, or it can be used as a blank for welded pipes and a thin plate blank for rolled thin plates. Main uses: Flat steel can be used as finished products to make hoops, tools and mechanical parts, and used as frame structural parts and escalators in buildings. Advantages 1. Flat steel is rolled

Hot-dip galvanized pipes are galvanized to improve the corrosion resistance of steel pipes. Hot-dip galvanized pipes are made by reacting molten metal with the iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution

Medium carbon steel is a carbon steel with a carbon content of 0.25% to 0.60%. It includes most high-quality carbon structural steels and some ordinary carbon structural steels. This type of steel is mostly used to make various mechanical parts, and some are used to make engineering structural parts. Medium carbon steel has good hot processing and cutting performance, but poor welding performance. The strength and hardness are higher than those of low carbon steel, but the plasticity and toughness

The full name of aluminized plate is “hot-dip aluminized steel plate”, which is similar to hot-dip galvanized steel plate in terms of manufacturing process. But its heat resistance is better than galvanized steel plate. Aluminum plate has the following 5 characteristics: 1. High temperature resistance: Due to the specific combination of the steel plate base material and the coating structure, an iron-aluminum alloy is formed, which makes the aluminum plate have excellent high temperature resistance. At 450℃, extremely high reflectivity
