The standard provisions in piping, mechanical properties, physical properties, the use of performance and process performance indicators, corresponding to the different steel grades. Performance metrics vary greatly. Mechanical properties: Tensile strength, yield intensity, elongation, hardness, impact energy; physical properties mainly refer to the grain size.
Includes use and process performance: anti-crush Test, flattening, flaring test, anti-H2S and CO2 corrosion test resistance.
What’s Burning? Name: Burn-in definition: The sintering temperature is too high or the sintering time is longer, the performance of the final product deterioration. Application areas: Mechanical Engineering (2) Powder Metallurgy (two people), powder metallurgy process and equipment over-burning, over-burning products over the firing temperature is called combustion. High sintering temperatures and sintering time are too long (or) resulting in a deterioration in the final performance of the Sintered product. Product combustion easy deformation, size requirements, blank or glaze and so on. Porcelain body fluid (glass phase) increases, grain boundaries become wider, prone to abnormal growth of crystals, crystal uneven, strength and density decreased. If the heating temperature close to the melting point, so that the grain boundary oxidation or even melting, resulting in the ability of metal plastic deformation completely disappear, if incineration will cancel the blank. Led combustion is due to the sintering temperature is too high, holding time too long
