加工模具時(shí)用的，由于模具的用途很廣，各種模具的工作條件差別很大，模具的工作條件不同，對(duì)其材料的性能要求也不同。下面來(lái)講講濟(jì)南模具鋼的基本性能及選用標(biāo)準(zhǔn)內(nèi)容吧。

The working conditions of all kinds of molds are very different, and the working conditions of the molds are different, and the performance requirements of the materials are also different. Let's talk about the basic properties and selection standards of Jinan die steel.

冷沖壓模具要求其材料具有高的強(qiáng)度，良好的塑性和韌性，高的硬度和耐磨性;

Cold stamping die requires its material to have high strength, good plasticity and toughness, high hardness and wear resistance;

冷擠壓模具要求其材料具有高強(qiáng)度、高韌性、高淬透性以及良好的耐磨性、熱穩(wěn)定性和切削加工性;

The cold extrusion die requires its material to have high strength, high toughness, high hardenability, good wear resistance, thermal stability and machinability;

熱作模具用鋼要求在工作溫度下保持高的強(qiáng)度和韌性、良好的抗蝕性、熱穩(wěn)定性和優(yōu)良的熱疲勞抗力。

The steel for hot work die is required to maintain high strength and toughness, good corrosion resistance, thermal stability and excellent thermal fatigue resistance at working temperature.

模具的各項(xiàng)性能要求有時(shí)是相互矛盾的。一般硬度越高，耐磨性就越高。在同樣的硬度下，鋼材碳含量越高，耐磨性也就越高。熱穩(wěn)定性與加入元素的種類(lèi)及數(shù)量有關(guān)，只有在高合金含量的情況下，才能達(dá)到所要求的抗軟化能力。

The performance requirements of the mold are sometimes contradictory. Generally, the higher the hardness, the higher the wear resistance. Under the same hardness, the higher the carbon content of the steel, the higher the wear resistance. The thermal stability is related to the type and quantity of the added elements. Only in the case of high alloy content can the required softening resistance be achieved.

韌性則與前二者相反.碳化物中合分元素增加，鋼材變脆，這樣就形成耐磨性和韌性之間以及穩(wěn)定性和韌性之間的兩對(duì)矛盾。

Toughness is opposite to the former two With the increase of alloying and separating elements in carbides, the steel becomes brittle, thus forming two pairs of contradictions between wear resistance and toughness and between stability and toughness.

在選擇模具材料時(shí)，應(yīng)先考慮模具的某些基本性能須能適應(yīng)所制造模具的需要。在一般情況下，主要是鋼的耐磨性、韌性、硬度和熱硬性以及熱疲勞抗力，這四種性能可以比較多方面地反映模具材料的綜合性能，可以在一定程度上決定其應(yīng)用范圍。

When selecting the mold material, some basic properties of the mold should be considered first to meet the needs of the manufactured mold. In general, it is mainly the wear resistance, toughness, hardness, thermal hardness and thermal fatigue resistance of steel. These four properties can reflect the comprehensive properties of mold materials in many aspects and determine their application range to a certain extent.

當(dāng)然對(duì)于一種模具的要求來(lái)說(shuō).可能其中的一種或兩種性能是主要的，而另外的一種改兩種是次要的。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.6886774.cn咨詢(xún)了解吧。
