What Are UNS S31803 Bolts Used For?

UNS S31803 Bolts are a form of threaded fasteners which have an external male thread. Generally, similar to screws, an Alloy S31803 Bolt tends to use a wide variety of head designs. The heads of these bolts have been designed  in such a way that it engages with the tool used to tighten them. Some stainless steel S31803 hex Bolt heads instead are able to lock the bolt in place, which would mean that this bolt does not move and a tool is only required for the nut end. Common kinds of bolt heads include hex, slotted hex washer, as well as the socket cap. The duplex grade stainless steel UNS S31803 Hex Head Bolt is available with a hexagonal head and threaded body. Many times the section that comes immediately under head may or may not be threaded depending on the bolt which has been selected.

UNS S31803 Bolts

The ASTM A182 specification covers standards meant for high tensile strength stainless steel bolting such as duplex grade UNS S31803 Hex Bolts. This specified stainless steel duplex grade ASTM A182 S31803 Threaded Rod is used for special purpose applications such as pressure vessels. Several grades of precipitation- hardened as well as duplex or ferritic- austenitic stainless steel classes have been covered by the ASTM A1082 specification. Selection of the stainless steel grade will be dependent upon the products design, service conditions, mechanical properties as well as characteristics related to the application.

For instance, the UNS S31803 Bolt is well suited for use in those applications which require a combination of properties such as high tensile strength, along with enhanced resistance to corrosion as well as ability to function at a wide range of temperatures between  300°C to about - 50 °C.

Stainless steel grade UNS S31803 is highly resistant to intergranular corrosion due to its lower content of carbon which prevents the formation of carbide precipitation on the grain boundary . In comparison to the other austenitic stainless grades such as alloy 316, the duplex grade UNS S31803   ASTM A1082 Bolts tends to exhibit better corrosion resistance properties with a higher level of resistance to stress corrosion cracking  in comparison to either alloy 304 or alloy 316 stainless grades. Pitting corrosion and crevice corrosion of the ASTM A1082 specification Alloy S31803 Fasteners is higher than that of stainless steel alloy 316. Due to its higher resistance to corrosion the alloy grade UNS S31803 is able to demonstrate better fatigue strength in corrosive media containing  environments than that of other typically used austenitic stainless steel specifications.

UNS S31803 Fasteners also referred to as 1.4462 or  F51 has good weldability properties which are similar to that of other stainless steel grades. the Low rate of thermal expansion in the ASTM A1082 duplex grade S31803 Bolts  reduces residual stresses after the performance of welding operation. Most manufacturers recommend using duplex welding electrodes similar to that of the parent steel i.e. UNS S31083 while welding UNS S31803 Fasteners. Electric arc welding processes tend to be  well suited for welding although oxyacetylene welding is not recommended by suppliers due to the possibility of carbon pick up in the weld area of the UNS S31803 Hex Head Bolt. Whilst a post weld annealing treatment is not a requirement for many applications, performing this treatment will give the UNS S31803 Bolt optimum corrosion resistance in severe application conditions.

 Bolting such as the ASTM A1082 UNS S31803 supplied according to this specification needs to conform to the requirements as mentioned in Specification A962/A962M as well. These requirements as covered by the specification include finish, thread dimensions, marking, certification, test methods, terminology, testing, optional supplementary requirements, and others.

Hence, these stainless steel Duplex Bolts S31803 can be successfully used as an alternative to most conventionally used stainless steel specifications across various applications where properties such as higher strength and resistance to SCC or stress corrosion cracking is required. The UNS S31803 Bolting is widely used in industries like the power generation, marine, brewing,  petrochemical and chemical engineering industries. Typical applications of the alloy include bolts for equipment’s like  bushes, flanges, shafts and fasteners.
