ASTM A350 Lf2 Flanges Manufacturing Process

Flange Forging

Compared to cast flanges, forged flanges typically contain less ASTM A350 Lf2 and are less likely to corrode. Forgings have superior mechanical qualities, a thicker structure, and a more streamlined shape.

Heat Treatment

The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds. The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds.

Forging Rolling

Roll forging is a forging technique that shapes a metal object by using opposing rolls. Although roll forging employs rolls to accomplish the desired material deformation, it is categorized as a metal forging procedure rather than a rolling procedure.

Rust Prevention

For steel flanges, conventional rust protection treatments include hot dip galvanizing, electro galvanizing (cold), varnish paint coating, black paint coating, black phosphating treatment, yellow (golden) paint coating, etc.
