Nickle Alloy Flat Welding Flange UNS S32750 1.4410 Super Duplex F53

Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.

Welding Process:

Required Equipment: A set of manual arc welding equipment, one handle-type angle grinder, one electric air hammer, and one straight edge.
Folding Welding Preparation: 1. Check and adjust the equipment to ensure normal operation; 2. Prepare φ4.0 J402 welding rods, which are preferably dried at 300°C - 350°C for one hour.
Folding Welding Process: 1. Assemble the cone and the large flange according to the drawing requirements, then divide the large flange into 8 equal parts; 2. Welding due to the thicker flange and larger groove, the use of segmental symmetrical, multi-layer welding is adopted.
Folding Welding Quality Requirements: The weld strength must at least match the strength of the base material. The weld surface should be flat and smooth, without defects such as burn-through, porosity, welding leaks, slag inclusion, undercutting, or incomplete welding. The weld reinforcement height should be less than 2mm.
Folding Notes for Attention: 1. When welding the base layer, always use J506 welding rod manual surfacing and welding with a small current. Strictly follow the welding process; 2: After welding each position, use a level to check the deformation of the flange plane; 3: While welding, use the air hammer to strike the weld to eliminate stress.

UNS S32750 / 1.4410 / F53:

Material to UNS S32760 (and the other specifications listed below) is described as a super duplex stainless steel with a

microstructure of 50:50 austenite and ferrite. The steel combines high mechanical strength (typically up to 570 MPa yield strength) and good ductility with outstanding corrosion resistance in marine environments. The alloy is supplied with a PREN (Pitting Resistance Equivalent) at >= 40.0 which guarantees high resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking. Ambient and sub zero (down to minus 50°C) notch ductility is good. These attributes mean that this super duplex steel can be used successfully as an alternative to 300 series stainless steel

(such as type 316), standard 22% Cr duplex steel (such as UNS S31803 / 1.4462 with PREN 33-34) and precipitation hardening stainless steels (typically 17/4PH).
