China Factory Stainless Steel Insert Fittings For PP-R Male Female Fitting
1)stainless steel 201 Chromium 15%, nickel 5%. High manganese content, very bright surface with dark bright.
VS Brass Insert
1). stainless steel is lighter The density of stainless steel is 7.93g/cm3, and that of brass is 8.89g/cm3. 2).better strength and toughness The tensile strength of stainless steel σb (MPa) ≥ 520, elongation δ5 (%) ≥ 40, H65 brass tensile strength
σb (MPa): ≥ 390, elongation δ10 (%): ≥ 10, 3). stainless steel insert is environmentally friendly Stainless steel insert only needs to polish, brass inserts need to be electroplated with nickel and chromium , the coating is unstable and easy to peel off;Brass inserts will release heavy metal during application and cause secondary pollution.
