Characteristic
304L Stainless Steel Pipe 18Cr-8Ni-low carbon As a low C 304 steel, in the general state, its corrosion resistance is similar to that of 304 steel, but after welding or stress relieving, its resistance to grain boundary corrosion is excellent; in the absence of heat treatment, it also maintains good corrosion resistance, and the use of the temperature - 196 ℃ ~ 800 ℃. It is used in the chemical, coal and petroleum industries where high resistance to grain boundary corrosion is required, as well as in field and open-air machines, heat-resistant parts for building materials and parts that are difficult to heat-treat.
Smooth inner wall of the pipe, low resistance to water transmission, can withstand high water flow rate erosion, solid solution treatment, the mechanical properties of the weld channel and the matrix, corrosion resistance is basically the same, deep processing performance is excellent.
18Cr-8Ni As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties; good hot workability such as stamping, bending, etc., no heat treatment hardening phenomenon (non-magnetic, use temperature -196℃~800℃).
