Summary
Three kinds of steel, 0.40% carbon steel, Cr-Mo case hardening steel and 304 stainless steel, are hydrostatically extruded at high temperatures up to 1300°C.
Above 900 °C, carbon steel and alloy steel can be extruded at high extrusion ratio. Surface roughness of product becomes small with higher extrusion ratio and it becomes minimum at a temperature depending on pressure medium and lubricant. Surface quality and dimensional accuracy of the extruded products are comparable with those by cold extrusion.
