Randhir Metal is one of the well-known manufacturing unit and supplier of Duplex Steel S31803 / S32205 (Bolts / Nuts), which always react more sensitively towards precipitation. Duplex S31803 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 Duplex S32205 Hex Head Nuts is further cooling down to 300 Degree C and should be undertaken as quickly as possible. Duplex S31803 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 Duplex S32205 Square Nuts, depending on the seam geometry, the thickness of the steel and the welding process. Therefore Duplex S31803 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 S32205 Eye Nuts is subsequent heat treatment, so-called solution annealing. For Duplex S31803 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 S32205 T-Nuts as rapidly as possible is advisable.
