1.2379 igh-carbon and high-chromium alloy tool steel AISI/ASTM D2 SKD11

Product Description:

1.2379 is a high-carbon, high-chromium alloy tool steel, corresponding to the Chinese GB standard grade Cr12Mo1V1, the American AISI/ASTM standard grade D2, and the Japanese JIS standard grade SKD11. Its detailed specifications are as follows:

- Chemical Composition: Carbon content 1.45%~1.60%, silicon content 0.10%~0.60%, manganese content 0.20%~0.60%, phosphorus and sulfur content ≤0.030%, chromium content 11.00%~13.00%, molybdenum content 0.70%~1.00%, vanadium content 0.70%~1.00%, nickel content ≤0.25%, copper content ≤0.30%.

- Performance Characteristics: After heat treatment, the hardness can reach approximately 63 HRC. It possesses high wear resistance, good hardenability, and dimensional stability, resulting in minimal dimensional changes in the mold during heat treatment and use. It also exhibits a certain degree of toughness, capable of withstanding certain impact loads without easily fracturing.

- Heat Treatment Process: Annealing temperature is 800-850℃, cooled to 600℃ at a rate of 10℃/h, then air-cooled, hardness ≤250HBW; quenching temperature is 975-1040℃, oil or gas cooling; low-temperature tempering temperature is 150-200℃, hardness ≥61HRC; high-temperature tempering temperature is 480-540℃, tempered more than twice, hardness ≥58HRC.

Equivalence

Applications:

Mainly used in manufacturing precision stamping dies, cold extrusion forming dies, deep drawing dies, blanking dies, and other cold working dies. It can also be used to make cutting tools such as knives and blades, as well as high-performance precision injection molds requiring good mirror finish or etching properties.
