Edit this paragraph Profile:
Factory hardness: S136
Soft annealed to 250 the highest characteristics of HB: The refining furnace (the VD) + refining electroslag remelting (ESR), the organization is more pure and subtle, excellent corrosion resistance, polishing, good wear resistance, machinability, For hardened When excellent dimensional stability. Purposes: corrosion and rust on the use of corrosive PVC, acetic acid salts, such as injection molding material or in a humid environment and storage molds. ● wear resistance in wear large injection molding materials (including thermoset injection molding) or die longer working hours, such as electronic parts, to abandon the style meal knives, utensils, etc. The smoothness of the surface of the production of optical products, such as cameras, sunglasses, chemical equipment and plastic products, etc..
Edit the S136 advantages of this paragraph:
The S136 is a plastic mold steel for excellent corrosion resistance, excellent production characteristics, and more of the following advantages: lower maintenance costs: after long-term use, the mold cavity surface remains the original smooth state. Mold when the operation or storage in a humid environment, no special protection. Lower production costs: the mold is not a result of the cooling water and corrosion due to the cooling cycle, increase die life. The above benefits, combined with the S136 high corrosion resistance, low maintenance costs and life mold, to achieve the best value for money. At the same time S136 after electroslag remelting (ESR) refinery, with the pure and subtle organization, so that the mold has good mechanical properties, high Teng Ning metal S136 finished map
Polishing performance. Purposes: S136 can be used with all of the mold, due to its special nature, is more suitable for special needs of the environment. Corrosion-resistant, resistant strain: the use of corrosive PVC the acetate salts (ACETATES0,) such as injection molding raw materials or mold work and storage in a humid environment, S136 resistant to water vapor, weak organic acids, nitrate, carbonate corrosion role through S136 mold made to operate in a humid environment, or corrosive plastic materials used in the normal state, will not rust contaminated. If the tempering to 250 ° C and polished to a mirror state, in particular, can show excellent corrosion resistance. Resistance to abrasion: the use of larger friction plastic material (including injection molding) or die a longer working hours, such as electronic components, disposable dinner knives, utensils and other. The surface of a high-quality finish: the production of optical products, such as cameras, sunglasses, chemical apparatus, syringes, analytical instruments and plastic products and so on.

Edit this paragraph welding:
Usually tool steel should be avoided whenever possible welding, easy to crack. If you do the preparatory work prior to welding, welding parts, such as preheating, are more likely to be successful, must be taken immediately after welding the following steps: 1, the elimination of stress - when the welding material in the soft annealed condition, must do stress relief. Temper - when the welding of the materials in the quenching - tempering state, must be done tempering.
Edit this paragraph heat treatment:
Annealing: protection of the state, heated to 780 ° C and then 10 ° C per hour speed furnace cooling to 650 ° C and then cooling in air. Stress relief: After rough machining, must be heated to 650 ° C, soaking for 2 hours, slow cooling to 500 ° C, and then cooling in air.
Edit this paragraph hardened:
Preheat temperature :600-850 ° C quenching temperature :980-1050 ° C temperature (° C) to maintain time (min) pre-tempering hardness (HRC)

Soaking time to reach hardening temperature start to the steel center, hardened must be protected in order to avoid decarburization and oxidation

Edit this paragraph quenching medium:
Quenching oil in a medium temperature of 200-550 ° C salt bath furnace and then cooling in air. Compressed air circulating air or the atmosphere
Edit this paragraph grinding:
Grinding technology, to avoid cracks and increase the life of the tool. If the material is ground, in the low-temperature tempering state during the grinding becomes very sensitive, only soft and open grain of the wheel to use, and must have good coolant.
Edit this paragraph polishing:
S136 in the hardened and tempered condition, with very fine polishing, the use of particle size 180-320 wheel or grindstone to do the preliminary grinding. 2, the use of abrasive sandpaper or a powder of particle size 400-800. 3, particle size of 12.6 and 3μm diamond paste, and polishing the fiber mat.
Edit this paragraph, photo-etching:
S136 very evenly organizations, very few impurities, it is suitable for photo-etching.
