Sachiya Steel International is one of the leading Manufacturer and Exporter of Duplex Steel S31803 Tube to Male Fittings, which has some exceptional features to offer such as fine finish, high tensile potency, rust – resistant, etc. These Duplex Steel S31803 Tube Fittings demonstrates exceptional fatigue potency, in addition to exceptional resistance to stress corrosion cracking, crevice, erosion, general corrosion and pitting in severe atmospheres. The construction of our Duplex Steel S32205 Compression Fittings contains of austenite pools enclosed by an incessant ferrite stage. These Duplex Steel S31803 Ferrule Fittings is about twice over the yield potency of customary austenitic stainless steel grades.
Our Duplex Steel S32205 Double Ferrule Fittings soaring temperature power is parallel to SS 430 in the array of 950 Deg C to 1150 Deg C. Meanwhile, these Duplex Steel S31803 Male Connector Fittings are also being offered in different sizes and shapes to our customers. Due to the possibility that other undesired metallic phases could arise in our Duplex Steel S32205 Male Connector Fittings, so further cooling down to 300 Degree C should be undertaken as quickly as possible.
These Duplex Steel S31803 Double Ferrule Tube Fittings can be welded according to the processes generally used for highly alloyed steels, i.e. the following procedures or combinations can always be used: submerged arc welding, TIG process, plasma welding, metal – active gas process, laser beam welding, and electron beam welding.
