Super Duplex Steel Heavy Hex Nuts, Super Duplex Coupling Nuts Exporter, Duplex Steel Hex Head Bolts Supplier in Mumbai India.

Ganpat Industrial Corporation is one of the well-known manufacturing unit and supplier of Duplex Steel (Bolts / Nuts), 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 Duplex Hex Head Nuts 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 Duplex Square 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 Eye Nuts 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.

Duplex Steel Bolts are mainly composed of duplex-grade stainless steel. Due to its superior mechanical qualities, low cost, and resistance to corrosion, Duplex is being utilized to replace most other steel varieties in items like Duplex 2205 Bolts.
Super duplex bolts and nuts offer greater mechanical strength and corrosion resistance than duplex and standard stainless steel grades. High tensile strength and resistance to chloride corrosion are both features of super duplex bolts. PREN, which must be at least 40 for super duplex grades, can be used to quantify the corrosion resistance of super duplex bolts and nuts.
