Stainless steel with high nickel, high molybdenum, copper, and nitrogen, and the microstructure of matrix metal is typical of 100% Austenite is called Super Austenite stainless steel.
Because super austenitic stainless steel is high in nickel and molybdenum and contains copper and nitrogen, it is easy to melt. Easy to bend, cracking, and so on, so super austenitic stainless steel is the stainless steel production process requirement of the highest, the most difficult variety, it is the concentrated embodiment of steel technology.
Normally, Weidouli can supply super austenitic alloy include 904L, 254SMO, AL-6XN & Alloy 20.
904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is a proprietary material imported from France H-S.
254SMO (UNS S31254) is a high corrosion resistant austenitic stainless steel with high nickel, high chromium, high molybdenum alloy design, and provides excellent corrosion resistance in severe corrosion environments such as high-temperature seawater.
AL-6XN is a typical 6 molybdenum (high molybdenum content 6.3%) super austenitic stainless steel.
Alloy 20 is stainless steel with extremely high corrosion resistance to sulfuric acid.
Upward discharge valves
Design Features
The gasket is placed in the concave groove of the valve body, the gasket can keep the elasticity for a long time and the sealing is reliable.
Integral forging valve core design, with better strength.
Enlarge the size of the stem and connection rod made the valves more stable and firm.
Waist drum structure valve bodies have good streamline, it can increase flow capacity and reduce medium deposition.
Spring-loaded packing design provides more reliable sealing and realizes packing seal online adjustment
Valve core have guide device to protect the stem from deviation
