S136 die steel has the advantages of pure and fine structure, excellent corrosion resistance, polishing performance, good wear resistance, machining performance and excellent dimensional stability when hardened.
S136 die steel hardness
S136 die steel factory hardness: about 190 HB; Heat treatment hardness 50-52HRC; S136H pre-hardening hardness: 27-35 HRC.
Chemical composition of S136 die steel

S136 die steel characteristics
1. Excellent corrosion resistance
2. Excellent optical rotation
3. Excellent wear resistance
4. Excellent machinability
5. Excellent stability during quenching
The benefits listed above, combined with the high corrosion resistance of Swedish die steel S136, provide low maintenance costs and high life of the mold, while S136 after electroslag remelting (ESR) refining, with a pure and fine organization, so that the mold has a good comprehensive mechanical properties, high polishing performance.
S136 die steel use
1, the production of corrosion resistance, corrosion to the use of corrosive PVC, acetate and other injection mold raw materials or must work in a humid environment and storage mold.
2, wear resistance in the use of large wear injection mold materials (including thermosetting injection molding die) or require the mold to have a long working time, such as electronic parts, disposable dining tools, utensils, etc.
3, its high smoothness surface is suitable for the production of optical products, such as cameras, sunglasses, chemical instruments and plastic products.
S136 steel and S136H difference
S136H die steel is pre-hardened, but the hardness is not very high, at about HRC30 degrees, there is no need to do heat treatment.
S136 die steel is a quenching material, very soft, need to be quenched to use, after quenching hardness can reach HRC48-52 degrees.
Comparison of s136 die steel and NAK80
1) Hardness is different, NAK80 is a pre-hardened die steel, factory hardness HRC38-41. After hardening, the hardness of S136 can reach HRC48-52.
2) The polishing performance of the mirror is different, and the polishing performance of s136 is better than that of nak80.
3) Different applications. NAK80 is mainly used for mirror polishing plastic products, do not need rust-proof plastic mold. S136 can be used for high mirror polishing plastic products, such as: optical mirror plastic products, and require anti-corrosion and anti-rust plastic mold.
