Export sales of malleable steel pipe fittings declined in 2022

Pipe fittings are crucial components used to connect, control, or change the direction and flow of f

Malleable cast iron is white cast iron that has been annealed. An annealing heat treatment transforms the brittle structure as the first cast into the malleable form.

First, the main factors affecting the treatment effectMary pipe pieces dealing with the right amount because of its range of metamorphism element requires very narrow, and thus more difficult to stabilize than ductile iron. This requires that the relevant process factors must strive to do less volatility. Treatment effect of malleable iron pipe fittings larger process factors are mainly the following aspects.
