304l stainless steel seamless pipe The corrosion resistance of stainless steel seamless tubes depends on the alloying elements contained in the steel.Chromium is the basic element to make stainless steel corrosion resistance, when the amount of chromium in steel reaches about 12%, chromium and oxygen in the corrosive medium, forming a very thin oxide film on the surface of the steel (self-passivation film), can prevent further corrosion of the steel matrix.In addition to chromium, stainless steel seamless tube commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet various USES of stainless steel structure and performance requirements.

First, stainless steel seamless tube wall thickness, it is more economic and practical, the thinner the wall thickness, its processing costs will rise substantially;
Secondly, the process of stainless steel seamless tube determines its limited performance, the general precision of seamless steel tube is low: uneven wall thickness, tube inner surface brightness is low, fixed length cost is high, and the inner surface and pitting, black spots is not easy to remove;
Third, stainless steel seamless pipe detection and shaping must be offline processing.Therefore, it shows its superiority in high pressure, high strength and mechanical structure material.
