Durable
Mantle’s tool steels have the durability needed for volume production and challenging plastics.
Mantle printed mold inserts have undergone over 1.65 million cycles in production, and counting
H13 has a hardness of over 50 HRC after heat treatment
420 has a hardness of over 50 HRC after heat treatment with excellent corrosion resistance

“We took a printed block of steel, cut away 75% of it, and were able to hold a 0.0007” tolerance.”

STABLE
Mantle’s tool steels remain stable during standard toolmaking operations like machining and EDM.
Little to no movement with machining, grinding, and other operations
No residual stresses after sintering
H13 TOOL STEEL
H13 is the workhorse of production-grade tools and can be hardened greater than 50 Rockwell C.
| Hardness (HRC) | 42 |
| Ultimate tensile strength (MPa) | 1,700 |

CASE STUDY
1.65 MILLION CYCLES AND COUNTING:
TESSY PLASTICS RUNS MANTLE’S METAL 3D PRINTED INSERTS IN HIGH VOLUME PRODUCTION
Mantle’s metal 3D printed inserts have proven to be as accurate and durable as traditionally fabricated inserts. All 3.3 million molded parts have passed Tessy’s internal quality control checks.
420 STAINLESS STEEL
420 Stainless Steel is the ideal tooling material when high-hardness is needed with corrosion resistance.
| Hardness (HRC) | 42 |
| Ultimate Tensile Strength (MPa) | 1,960 |
| Elongation (%) | 5.1 |
