Stainless Steel 304H Pipes

Silver Tubes is a known manufacturing house of Stainless Steel 310H Pipes, which are the most susceptible of the austenitic stainless steels to stress corrosion cracking (SCC) in halides because of their relatively low nickel content. Stainless Steel 310H Seamless Pipes have been used very successfully in fresh waters containing low levels of chloride ion. Environments which source SCC in Stainless Steel 310H Welded Pipes are theexistence of halide ions (usually chloride), residual tensile pressures, and temp over about 120 Degree F (49 Degree C). Stainless Steel 310H EFW Pipes has excellent corrosion resistance in a wide variety of environments and when in contact with different corrosive media. Stainless Steel 310H ERW Pipes has good resistance to oxidation in intermittent service up to 870 Degree C and in continuous service to 925 Degree C.

Pitting and crevice corrosion in Type 310H Pipes can occur in environments containing chlorides, whereas stress corrosion cracking can occur at temperatures over 60 Degree C. Generally, chloride is considered to be the limit for Grade 310H Pipes, particularly if crevices are present. Higher levels of chloride in SS 310H Pipes might cause crevice corrosion and pitting. Stresses may result from cold deformation of 310H Stainless Steel Pipes during forming or by roller expanding tubes into tube sheets or by welding operations which produce stresses from the thermal cycles used. Stress levels in Alloy 310H Pipes may be reduced by annealing or stress relieving heat treatments following cold deformation, thereby reducing sensitivity to halide SCC.
