Sachiya Steel International is one of the Leading Manufacturer And Exporter of High Quality Stainless Steel 347H Socket Weld Fittings, which applies to both quench – annealed and welded material. In certain applications, e.g. suction rolls in paper mills, the resistance of Stainless Steel 347H Forged Socket Weld Elbow to corrosion fatigue has a crucial bearing on its service life. Laboratory tests have shown that Stainless Steel 347H Forged Socket Weld Tee has far better fatigue strength under corrosive conditions. The force requirement for bending is about twice as high for Stainless Steel 347H Forged Socket Weld Cap, but when the proof strength is exceeded, the plastic deformation takes place just as easily in austenitic stainless steels.
However, under service conditions where the risk of stress corrosion cracking starts to increase for example where the temperature of Stainless Steel 347H Forged Socket Weld Cross is nearly 150 Degree C (300 Degree F) in oxygen – bearing environment, and heat treatment is recommended even after moderate cold bending. The mechanical machining of Stainless Steel 347H Forged Socket Weld Union always requires an adjustment of cutting data and machining method to give satisfactory results.
When turning is undertaken with carbide – tipped tools, the cutting speed should be reduced by 20 % for finish machining and 60 % for rough machining compared to the cutting speeds applied for Stainless Steel 347H Forged Socket Weld Plug.
