Hardened plastic mold steel

Pre-hardened plastic mold steels (hardness -31 HRC) Hardened plastic mold steels (hardness -62 HRC) Case hardening steels (hardness -62 HRC) Surface finished steels (700-3500 HV)... [Pg.447]

The desired plastic forming is mostly carried out under hydraulic presses, to ensure the required material properties. After forming, the steel manufacturer carries out suitable heat treatment, which may be either preliminary heat treatment prior to machining, or final heat treatment in the case of pre-hardened plastic mold steels. [Pg.449]

The pre-hardened plastic mold steel 1.2312 (40CrMnMoS8-6) is not suitable for molds with high surface requirements or mechanical stresses, because of its high sulphur content. In combination with manganese, the sulphur forms long-chain sulfides that can cause the following problems ... [Pg.452]

CrMnNiMo8-6-4). Figure 3.7 illustrates the merits of the new plastic mold steel 2738 mod. IS, which covers most applications for hardnesses up to 38 HRC, due to its chemical composition and resultant properties, helping to significantly simplify the material concept in the case of pre-hardened plastic mold steels. [Pg.461]

The material 1.2738 is the material most often used for larger molds. For best graining results, this steel was further developed and is now available as 2738 mod. TS. Other quenched and tempered steels are 1.2311,1.2711, and 1.2316 as a corrosion resistant material. For small molds or as mold inserts with high hardness, through hardened plastic mold steels such as 1.2343,1.2344, and 1.2767 can be used. 1.2083 is available as a corrosion-resistant variant. [Pg.596]
