Hardness: annealed state, after vacuum heat treatment in refining raw materials [/ Guessed may request] Name: 168 Location: Sweden Sweden Assab Assab RAMAX 168 high corrosion resistance pre-hardened plastic mold steel [Product Description] 168 high chromium stainless steel mold, played before tempering after insult. Have the following characteristics: · Excellent corrosion resistance · Excellent compressive strength ? Any size, hardness distribution average * Excellent machinability comprehensive advantages listed above, makes excellent production characteristics. Wherein "excellent corrosion resistance", has the following benefits: lower maintenance costs · low production costs. Since cooling water from corrosion effects, therefore, to ensure a consistent period of time. Moreover, "excellent machinability" has the following benefits: lower mold production costs because --- again before milling and drilling process, less wear of the blade opening --- cutting speed can be increased, thus shortening 168 in the pre-processing time state played hard, the following cost saving benefits: ? reduce the processing steps required to reduce the weight · · · surface normal manufacturing tolerances no black, make props and minimize mechanical losses Surface no decarburization chemical composition of carbon 0.33% Si 0.35 Mn 1.35 Cr 0.12 16.7 sulfur standard AISI420F factory state quenching and tempering to -340HB applications ● Color Code Black plastic mold mold base / plate, with S136 168 molds and inserts can ELMAX a perfect polished stainless steel mold base ● less demanding plastic and rubber mold plastic extrusion die ● ● ● structural parts plastic mold mold base / plate, 168 with S136 mold and ELMAX inserts can become perfectly polished stainless steel mold base ● less demanding plastic and rubber mold plastic extrusion die ● ● physical properties of the steel structural components insult hard, tempered to 340HB data at room temperature and high temperature.
