What are the important and decisive elements in the selection of Shandong die steel? The forming method can be selected from two basic material types. Hot working tool steel, which can withstand the relatively high temperature of die casting, casting and kneading. Cold working tool steel is used for blanking and shearing, cold forming, cold kneading, cold forging and powder pressure forming.
Plastics: some plastics produce corrosive by-products, such as PVC. Factors such as condensation, corrosive gases, acids, cooling / heating, water or storage conditions caused by prolonged strikes can also cause corrosion. In these cases, die steel made of stainless steel is recommended.
beplay全站app安卓标准：大标准beplay全站app安卓常常运用预硬钢。 全体淬硬钢常常用于小标准beplay全站app安卓。beplay全站app安卓运用次数：长时间运用（> 1 000 000次）的beplay全站app安卓应运用高硬度钢，其硬度为48-65 HRC. 中等长时间运用（100000到1 000 000次）的beplay全站app安卓应运用预硬钢，其硬度为30-45 HRC. 短时间运用（<100 000次）的beplay全站app安卓应运用软钢，其硬度为160-250 HB.
Mold standard: large standard mold often uses pre hardened steel. All hardened steels are often used for small standard dies. Mold application times: high hardness steel with 48-65 HRC shall be used for long-term application (> 1 000 000 times). Pre hardened steel with 30-45 HRC shall be used for medium long-term application (100000 to 1 000 000 times). Soft steel with 160-250 HB shall be used for short-term application (< 100 000 times)
表面粗糙度：许多塑料beplay全站app安卓制造商对好的表面粗糙度感兴趣。 当添加硫改善金属切削性能时，表面质量会因此下降。硫含量高的钢也变得更脆。影响材料可切削性的首要要素是什么？钢的化学成分很重要，钢的合金成分越高，就越难加工。 当碳含量添加时，金属切削性能就下降。
Surface roughness: many plastic mold manufacturers are interested in good surface roughness. When sulfur is added to improve metal cutting performance, the surface quality will decrease. Steel with a high sulfur content also becomes more brittle. What are the primary factors that affect the machinability of materials? The chemical composition of steel is very important. The higher the alloy composition of steel, the more difficult it is to process. When the carbon content is added, the cutting performance of metal decreases.
