310 Ss Pipe

310 ss pipe

Stainless steel pipe is divided into stainless steel seamless pipe and stainless steel welded pipe (welded pipe) two categories, according to the different manufacturing process can be divided into: Hot rolling, extrusion, cold drawing and cold rolling these basic types, according to the section shape can be divided into round pipe and shaped pipe, widely used is round steel pipe, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other shaped stainless steel pipe.

For the steel pipe under fluid pressure to carry out hydraulic tests to test its pressure resistance and quality, under the specified pressure does not leak, wet or expansion qualified, some steel pipe also according to the standard or the requirements of the demander flange test, flaring test, flattening test.

Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid tube blank perforated into a tube, and then made of hot rolled, cold rolled or cold drawn. The specifications of the seamless steel pipe are expressed by the outer diameter * the wall thickness of millimeters.

Chemical composition

Chemical composition of 310S (%) :

Ni nickel: 19.00-22.00

Cr Chromium: 24.00-26.00Si silicon < = 1.50

A surname = 2.00

C carbon = 0.08

sulfur = 0.030

P p p = 0.035

310s is austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance, because of the higher percentage of chromium and nickel, 310s has much better creep strength, can continue to operate at high temperatures, with good high temperature resistance.

Density: 8.0g/cm ³, mechanical properties after solution treatment: yield strength ≥205, tensile strength ≥520, elongation ≥40, hardness test: HBS≤187,HRB≤90,HV≤200

Stainless steel pipe is a grade of stainless steel produced according to ASTM standards in the United States. 304 stainless steel pipe is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe. 304 contains 19% chromium and 9% nickel.
