Flowforming is an advanced cold forming process, used to manufacture dimensionally precise, seamless metal components in rounded shapes. The technology offers a number of advantages, including very high precision, the ability to use very thin walls or even variable thickness walls, refined grain structure and uniformly oriented texture that helps create higher yield and tensile strengths, and working with pre-hardened metals in ways that eliminate further grinding, machining, et. al. See flowforming animations.
On the materials side, Inconel 718 is a precipitation hardenable nickel-based steel alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F. This alloy also has excellent weldability.
If you’re building mortar tubes that have to be light enough to carry, while containing and channeling the controlled explosions that send mortar bombs on their way, the attributes of flowforming and Inconel 718 make them an attractive combination. The US Marines certainly think so…
