Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
The steel rebar for reinforced concrete refers to the straight or coiled steel rebar used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel rebar and deformed steel rebar. The delivery state is straight rebar and coiled round rebar. Due to the effect of the ribs, the deformed steel rebar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel rebars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.
1. For pipelines. Water, gas pipes, steam pipes, and oil and gas trunk lines. 2. Tubes for thermal equipment. Superheating pipes, high temperature and high-pressure boiler pipes for locomotive boilers. 3. For the machinery industry. Aviation structural tubes, automobile axle tubes, tractor structural tubes, etc.
Round bars are divided into three types: hot rolled round bars, forged round bars and cold drawn round bars according to the process section. According to the chemical composition (ie carbon content), it can be divided into low carbon steel round steel, medium carbon steel round steel and high carbon steel round steel. According to the quality of steel, it can be divided into ordinary carbon steel round steel and high-quality carbon steel round steel. According to the use, it can be divided into carbon structural steel and carbon tool steel.
