What is the function of stainless steel pipe?

The heat treatment of stainless steel pipes is generally to reduce the grain boundary area, reduce hardness and toughness, and make the metal pipe more durable. For what happened, it is necessary to analyze the whole process of its thermal history. Heat treatment is generally in the latter step, and the temperature should not be too high.

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.

What is carbon steel what is carbon steel?

1. Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
