Which steel of NAK80 mold steel and S136 mold steel is good?
NAK80 mold steel and S136 mold steel are commonly used high -quality mold steel. They are widely used in injection plastic accessories processing. So which steel of NAK80 mold steel and S136 mold steel is good?
The following two mold steels will be compared in detail:
1. Material composition:
(1) NAK80 mold steel is mainly composed of nickel, aluminum and steel, which contains high nickel and aluminum content.
(2) S136 mold steel is a kind of stainless steel, which is mainly composed of chromium, nickel and steel. The material composition of the two determines its performance and characteristics in the processing process.
2. Hardness and wear resistance:
(1) NAK80 mold steel has high hardness and good abrasion resistance, and is suitable for the production of large -scale injection molding accessories. Its hardness is usually between 37-43 HRC, which can effectively resist wear and scratches and extend the service life of the mold.
(2) The hardness of S136 mold steel is usually between 48-52 HRC, which is relatively high, so it is more applicable in some applications with higher hardness requirements.
3. Corrosion resistance:
(1) Because S136 mold steel is stainless steel, it has good corrosion resistance and can resist the erosion of the corrosive media such as acid and alkali.
(2) NAK80 mold steel is slightly inferior to corrosion resistance.
4. Processing performance:
(1) NAK80 mold steel has good processing performance and is easy to cut and processed. It has a high thermal conductivity and fast cooling speed, which is conducive to improving production efficiency.
(2) Because of the high hardness and relatively difficult processing of S136 mold steel, it is necessary to use the appropriate cutting tools and processes.
5. Size stability:
(1) NAK80 mold steel has good size stability and can maintain the accurate size of injection molding accessories.
(2) S136 mold steel is small due to high hardness and small contraction rate, so it is more applicable in some applications with strict size requirements.
In summary, NAK80 mold steel and S136 mold steel are high -quality mold steel, which have their own characteristics and scope of application. The choice of steel depends on specific application requirements, such as product requirements, production batch, wear resistance requirements, etc. In practical applications, comprehensive considerations can be made based on these factors, and appropriate mold steel is selected in combination with experience and actual conditions.
