Stainless steel pipe 304 national standard wall thickness of 0.25mpa, 0.6mpa, 1.0mpa, 1.6mpa, 2.5mpa, 4.0mpa, 6.3mpa, 10.0mpa these kinds of.
The most important elements in 304 are Ni and Cr, but are not limited to these two elements. Industry common judgment that as long as the Ni content is greater than 8%, Cr content is greater than 18%, can be considered as 304 stainless steel. This is also why the industry will call this type of stainless steel 18/8 stainless steel reason.
1, according to the production method of classification: can be divided into seamless pipe (cold-drawn pipe, extruded pipe, cold-rolled pipe), as well as welded pipe (straight-seam welded pipe, spiral welded pipe, gas-shielded welded pipe, arc welded pipe, resistance welded pipe).
2, according to the cross-section shape classification: can be divided into round steel pipe, and rectangular pipe and so on.
3, according to the wall thickness classification: can be divided into thin-walled steel pipe, thick-walled steel pipe.
4, according to the use of classification: can be divided into civil tube divided into round tube, rectangular tube, flower tube, generally used for decoration, construction, structure and so on.
5, according to steel pipe specifications: can be divided into large-type steel, medium-type steel, small-type steel and so on.
6, at present, the commonly used stainless steel pipe materials are: TP304, TP304L, TP321, TP321H, TP316, TP316L, TP316Ti, TP310S, TP317L, TP347H and so on.
