NXF DIN ISO UNI ASME Standard S32205 S31803 S32760 S32750 M6-M36 Duplex Stainless Steel fastener Hexagon Nut
Product Description
Duplex stainless steel S32205 Chromium, nitrogen, molybdenum content is high, this kind of steel has a good corrosion performance. The biphase structure contributes to high strength and high resistance to stress corrosion cracking. Duplex stainless steel also has good weldability. Excellent corrosion resistance, high resistance to stress corrosion cracking and corrosion fatigue; High mechanical strength, good wear and fatigue resistance; Low thermal expansion.
The hexagon nut is used with bolts and screws to connect and tighten the parts. Among them, type I hexagon nuts are the most widely used, and C-class nuts are used for machines, equipment or structures with rough surfaces and low precision requirements. Class A and Class B nuts are used on machines, equipment or structures with relatively smooth surfaces and high precision requirements. The thickness m of type II hexagon nuts is thicker, and it is mostly used in occasions where installation and disassembly are often required. The thickness of the hexagonal thin nut m is thin, and it is mostly used in cases where the surface space of the connected parts is limited.
