Commonly Metal Stamping Tooling Materials And Uses

Uses: Commonly used as materials for shaft parts.

Mechanical properties: good mechanical processing performance and strength hardness, quenching and tempering treatment, quenching temperature 820°~850°, return water temperature 600°~650°, HRC40°.

Uses: It is often used for the block (insert) of engineering molds or continuous molds and punches for punching small holes. Many tools such as ordinary milling cutters, drills, wire taps, etc. are also suitable.

Mechanical properties: high hardness, good wear resistance, complicated heat treatment process. Hardness HRC62°~64°.

Uses: Male molds, female molds and molds with higher requirements, such as stripping of continuous molds of stainless steel shrapnel, etc.

Uses: Stripping, up and down pads, splints with higher requirements, female and male molds with lower requirements.

Mechanical properties: heat treatment quenching temperature 760°, return water temperature 140°~250°, hardness HRC50°~58°.

Uses: Commonly used in male and female molds of higher density molds.

Mechanical properties: Hardness and wear resistance are better than SKD, and the deformation coefficient is less than SKD. The heat treatment quenching temperature is 980°~1050°, the return water temperature is 180°~250°, and the hardness is HRC55°~62°.

Uses: Stripping, underlaying, female and male molds with lower requirements.

Mechanical properties: heat treatment quenching temperature 950°~980°, return water temperature 180°~250°, hardness HRC50°~56°.

The electrical processing performance is good, the mechanical processing performance is poor, and no heat treatment is required after processing. Due to the compact internal molecular structure of the material, the polishing performance is good.

Uses: upper and lower mold seat feet, heightening boards, supporting boards, lower backing boards, splints.

Gray cast iron (pig iron), commonly used grades of gray cast iron HT30~54.

Uses: Mould base, general machine bed.
