Duplex Fasteners Specification

Ganpat Industrial Corporation is one of the well-known manufacturing unit and supplier of Duplex Fasteners, which always react more sensitively towards precipitation. Duplex Hex Head Bolts should be ensured that the temperature range between 950 Degree C and 700 Degree C is traversed in no more than two minutes. Due to the possibility that other undesired metallic phases could arise, these DSS Hex Bolt is further cooling down to 300 Degree C and should be undertaken as quickly as possible. Duplex Square Bolts are also easy to weld according to the usual rules for welding stainless steels. Extremely low and extremely high heat input should be avoided in these Super Duplex Stainless Steel Bolt Nuts, depending on the seam geometry, the thickness of the steel and the welding process. Therefore Duplex Eye Bolts is necessary to monitor inter – pass temperature and the heat input during the welding process. The safest way to a balanced ferrite / austenite ratio in the weld seam of these Duplex Steel Stud Bolt is subsequent heat treatment, so-called solution annealing. For Duplex T-Bolts, holding times of 2 minutes to 3 minutes for each mm of wall thickness at temperatures around 1080 Degree C are sufficient to achieve a balanced austenite / ferrite ratio. After annealing, cooling of these Duplex T-Nuts as rapidly as possible is advisable.
