P20 steel is widely regarded as one of the best choices for molds that need a combination of toughness and wear resistance. Its composition, which includes chromium and nickel, allows it to withstand significant wear during the molding process while maintaining its mechanical properties. The steel also boasts excellent machinability, making it a favorite among mold makers who require precision and efficiency in their work. Additionally, P20 steel is often pre-hardened, helping to streamline production and reduce processing time.
Known for its exceptional toughness and thermal stability, H13 steel is a hot work tool steel that offers excellent wear resistance. This makes it suitable for high-temperature applications and processes where molds experience significant thermal fatigue. H13's chemical composition, which includes molybdenum and chromium, contributes to its efficacy in harsh environments. Its wear resistance ensures that it holds up well even under continuous operation, making it an ideal choice for high-performance plastic injection molds.
S7 steel is another versatile option popular in the mold-making industry. It is a shock-resistant tool steel that can withstand heavy impact, making it an excellent choice for molds used in industries where durability is paramount. S7 also has good wear resistance, particularly in applications involving abrasive materials. Its toughness makes it a reliable material for molds that undergo significant stress and fatigue, ensuring longevity and consistent output.

D2 steel is recognized for its high wear resistance, making it an excellent option for molds requiring sharp detail and precision. With a high carbon content, D2 can achieve hardness levels that enhance its durability and extended service life. However, it is important to note that D2 is less tough compared to other steels; thus, it is most suitable for molds that do not experience heavy shock loads. Its resistance to wear ensures that molds crafted from D2 maintain their features over extended usage.
NAK80 steel combines exceptional polishability with high wear resistance, often resulting in superior surface finishes for molded products. This steel is known for its consistency and reliability, making it a preferred material for high-precision molds. Its low thermal expansion coefficient enhances shape retention during the molding process. With a composition that includes manganese and chromium, NAK80 provides both toughness and resistance to wear, ensuring that molds continue to perform at high levels even after extensive use.
When it comes to choosing plastic mold steel with high wear resistance, the selection of the right material can significantly impact production efficiency and product quality. Each of the steels mentioned offers unique benefits, and the choice will largely depend on the specific application requirements. It is crucial to match the steel's properties to the demands of the molding process to maximize productivity and minimize downtime.
