Analyses the problems in the process of h
    Carbon, nitrogen can be expanded and the stability of austenite, so as to improve the high temperature strength of heat resistant steel.Are too many in steel containing chromium, manganese, can significantly improve the solubility of nitroge...

Analyses the problems in the process of h
    Nickel and manganese can be formed and the stability of austenite.Nickel can improve high temperature strength of austenitic steel and improve the carburizing resistance.Although manganese can form generation of nickel austenite, but the dam...

Analyses the problems in the process of h
    Besides using sand casting, casting method can also be used for precision casting process to obtain a smooth surface, size precision products.For synthetic ammonia and ethylene cracking in high temperature furnace tube often adopt the method...

Analyses the problems in the process of h
    Heat resistant steel and stainless acid-resistant steel are crossed each other on the using range, some characteristics of stainless steel with heat resistant steel, can be used as both stainless acid-resistant steel, also can be used as hea...

How to improve the quality of the surface
    Layering thickness of as influenced by the surface quality, precision casting surface quality of the product along with the peak, with the decrease of the thickness of layered surface quality began to decline, reduced to roughness.Reason ana...
