304 stainless steel tube quality and performance

304 stainless steel tube quality and performance is determined according to need, different needs, have a different element content. The higher the carbon content of carbon, the higher the hardness, but the worse its plasticity and toughness.


Sulfur is a harmful debris in steel, high sulfur steel in high temperature pressure processing, easy to crack, usually called hot brittle. Phosphorus can make steel plasticity and toughness decreased significantly, especially in the low temperature is more serious, this phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus to be strictly controlled.

But on the other hand, in the low-carbon steel contains high sulfur and phosphorus, can make it easy to cut, to improve the machinability of steel is beneficial. Manganese can improve the strength of fertilizer pipe, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, high manganese content of high alloy steel (high manganese steel) has good wear resistance and other Physical performance.

Silicon can improve the hardness of steel, but the plasticity and toughness decreased, electrical steel contains a certain amount of silicon, can improve the soft magnetic properties. 304 seamless tube inner surface mechanical polishing with rotation and linear polishing. 304 seamless tube heat resistance is high temperature, both anti-oxidation or resistance to gas medium corrosion performance that is thermal stability, while at high temperatures, there is sufficient strength that is strong heat.
