NXF DIN ISO UNI ASME Standard S32205 DUPLEX UNS S31803 M6-M36 Duplex Stainless Steel fastener Hexagon Bolt
Product Description
Duplex stainless steel S32205 DUPLEX UNS S31803 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.
Hexagon head bolt is a common mechanical connection. Its hexagonal head is easy to tighten or disassemble with a wrench. Usually made of carbon steel, stainless steel and other materials, with good strength and corrosion resistance. Its specifications are diverse, and the corresponding size can be selected according to different needs. Widely used in construction, machinery manufacturing, automotive and many other fields, by threading and nut coordination, can firmly connect parts, in ensuring structural stability plays a key role.
