What Are The Components Of Stainless Steel Pipe Fittings?

Stainless Steel Weld Fittings has a good application in many industries, so what are the components of stainless steel pipe fittings?

1. The mass fraction of silicon in cast steel is 0.2%-0.45%, and this content range has little effect on mechanical properties. Silicon needs to have a certain content to ensure the deoxidation of steel. Therefore, silicon is a beneficial element in steel.

2. The performance of carbon steel mainly depends on the carbon content. As the carbon content in steel increases, the strength and hardness of steel increase, and the plasticity and toughness decrease.

3. Sulfur is a harmful element in steel, mainly present in steel in the form of iron. It forms a eutectic with iron, and its melting point is 989 degrees, which is much lower than the melting point of steel. During the solidification of steel, sulfides often precipitate at the grain boundaries of steel. Due to the low strength and brittleness of steel, the mechanical properties of steel are greatly reduced, and hot brittleness is easily generated at high temperatures. If the molten steel is not deoxidized and contains more FEC, the sulfide forms a ternary eutectic with iron and Fe, with a low melting point (about 940 degrees) and greater harm. Sulfur also has an adverse effect on the weldability of steel. Therefore, sulfur should be removed as much as possible during the steelmaking process.

4. Phosphorus is also a harmful impurity in steel. The smaller the better, the mass fraction is required to be less than 0.06%.

5. The mass fraction of manganese in cast stainless steel pipe fittings is 0.5% to 0.8%, and its function is deoxidation and desulfurization.
