Ubique Alloys Pvt. Ltd is a renowned manufacturing and trading firm of Alloy Steel 4340 Fasteners, which is used in Coastal balustrading, Boat fittings, Chemical transportation containers, Heat exchangers, Mining screens, Nuts and bolts, Springs, Medical implants, etc. In general, media that do not corrode Alloy Steel 4340 Washers will not attack these molybdenum-containing grades. For example, steel cylinders and tanks are manufactured in Alloy Steel 4340 Screws, have proved to offer exceptional resistance in acidic and hard water areas. The austenitic structure also gives this Alloy Steel 4340 Nuts excellent toughness, even down to cryogenic temperatures. Used in constructions, making of home appliance and electronics, these Alloy Steel 4340 Bolts are known for their rich features such as ability to bear high mechanical stress, thermal stability, accurate dimension, sturdy construction, seamless finish and resistance to corrosion.
Annealing for Alloy Steel 4340 Stud Bolts is carried out between 1850 Degree F / 2050 Degree F (1010 Degree C / 1120 Degree C) followed by a water quench, when a hardness will be obtained. Where condensation of sulfur-bearing gases occurs, these AS 4340 Fasteners are much more resistant than other types of steels. Annealing for Alloy Steel 4340 Flat Washers is essential to restore ductility and to lower hardness for subsequent forming operations. Alloy Steel 4340 Hex Head Screws has excellent resistance to inter-granular corrosion in the as-welded condition.
