Round steel

Classification by steel quality According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel. (1) Ordinary carbon structural steel, also known as ordinary carbon steel, has wide restrictions on carbon content, performance range and content of phosphorus, sulfur and other residual elements. In China and some countries, it is divided into three categories according to the guaranteed conditions of delivery: Class A steel (Class A steel) is steel that guarantees mechanical properties. Type B steels (Type B steels) are steels with guaranteed chemical composition. Special steel (C-type steel) is a steel that guarantees both mechanical properties and chemical composition, and is often used to manufacture more important structural parts. China produces and uses the most A3 steel with a carbon content of about 0.20% (Class A No. 3 steel), which is mainly used for engineering structures.


What is the function of stainless steel pipe?

Steel pipe purchasing skills

How to choose the steel pipe 1. The color and luster are generally uniform, the inner and outer walls are smooth and flat, and there are no defects such as bubbles, depressions and impurities that affect the surface performance. 2. It depends on whether the logo on the product is complete. The steel pipe must have the manufacturer's name or trademark, production date, product name, specification size, implementation standard number, etc., and the steel pipe must have the product name, nominal outer diameter, pipe series S, etc. , the handwriting should be clear, and check whether the logo is consistent with the actual. 3. You should buy pipes and fittings of the same brand. Since the raw materials of products of different brands may be different, there will be unfavorable factors for the welding of pipes and fittings, and long-term use will cause leakage at the weld. 4. Good steel pipes have high strength rather than being broken, so the quality of steel pipes cannot be judged by whether they can be broken. Because the impact resistance of steel pipes is better than that of real steel pipes, steel pipes are easier to smash, and those that cannot be smashed are often steel pipes.
