1. As a leading Incoloy pipe & tube supplier, DINGSCO produces and manufactures Incoloy 800H valve stem to match the pipes & tubes.
2. INCOLOY® alloy 800H (UNS N08810) had been known for some time that higher carbon alloy 800 had higher creep and rupture properties than low-carbon material. For that reason, Special Metals had melted to a carbon range of 0.05 to 0.10% except for special orders where customers specified a lower carbon content.
3. Incoloy 800H valve stem is a kind of pipe fittings manufactured by forming Incoloy 800H welded pipes. In the pipeline system, the stem has the function of changing the direction of the pipeline. Its important role determines that it is one of our best-selling fitting products.
