1、高溫強度和韌性好,耐磨性較佳,易切削;
2、SKD11是一種有很好強度、韌性及耐熱平衡性的冷模具鋼,近年來隨著各向同性產(chǎn)品的開發(fā)而日益向高韌性等方面發(fā)展,它可以使模具壽命更長,效能更穩(wěn)定,且易於加工,熱處理變形小。
產(chǎn)品特點
(1)進行了真空脫氣精煉,囙此內(nèi)部質(zhì)量極為清潔。
(2)機械加工性良好。
(3)淬透性良好,空冷就能硬化,無需擔(dān)心淬裂。
(4)熱處理變形非常小,淬火偏差極小,最適合有精度要求的模具。
(5)耐磨性極為優(yōu)秀,最適合用作鏽鋼或高硬資料的沖裁模。
(6)韌性良好。
SKD11在鋁、鋅壓鑄用模具材料方面,應(yīng)用最為廣泛,此鋼含有鎢成分之耐高溫高級合金鋼,適用於熱作,鋁、鎂、鋅、銅合金壓鑄模,切槽刀,剪刀及熱鍛動作,塑膠型模,熱作鉸刀,軋刀,一般熱作鍛模,熱螺栓模,熱間各種工具等。
SKD11 is a high wear resistance and toughness general cold die steel, high carbon high chromium alloy tool steel and vacuum degassing refining steel, steel purity, with a good quenching, quenching deformation of small good quenching. The steel can be processed by ball annealing and softening, and can be processed well, fine and uniform carbide particles are not required to be worried about the quenching cracking and strengthening elements molybdenum and vanadium.
SKD11 is, Hitachi and Datong steel mills have production, Hitachi SKD11 production of SLD goods called (the latest improved version called SLD-MAGIC), Datong steel mill product name is DC11. Both in the mainland have set up factories in the industry's most famous, the price is also the highest. This steel is a kind of cold working die steel in the wide application of the world. The electric furnace smelting and the electroslag remelting, high purity, better toughness, uniform structure, has good high temperature strength, toughness and anti fatigue properties at high temperature, withstand sudden changes of temperature.
High hardness, high wear resistant eutectic carbide uniform, good toughness, not easy to crack, after quenching hardness >62HRC. In 525 C nitriding processing time for 20h/30h/60h, ammoniation layer depth 0.25mm/0. 30mm/0. 35mm, parts of the surface hardness 1250HV; at 570 C nitriding processing time for 2h, the depth of the nitrided layer 10 ~ 20 m, the surface hardness of the parts 950HV.
