QT HRC56 Corrosion-resistant Stainless Steel Round Bar For Plastic Mould
Product Introduction
Chinese Standard GB/T 4Cr13 stainless die steel properties high hardness after quenching than 3crl3 some corrosion resistance. use for the cutting tools, nozzle, value seats and so on. 1crl7Ni2 characteristics and strong resistance to nitric acid corrosion. Use of high hardness and high wear resistance for the heat pumps, valves, valve bearings, medical equipment, springs and other parts.
1.2083 is a tool steel in the group of plastic mold and stainless in matesitic (AISI420)So, it can stand for corrosive and can be quench to enhance it's strength together with corrosive resistance properties.Hardness can reach up to 56 HrC , this also benefit to polishing properties and can do texturing.Suitable for plastic mold that need corrosive resistance such as amino plastic,thermoplastic which has severe decompose of acitic acid as well as PVC plastic

General Applications
2083 is in the class of stainless steel and tooling for plastic mould.Its reputation stand by the corrosive resistance properties. Rust free throughout storage period Good for mold application in high humidity, water cooling condition Suitable for any plastic mold, mold that require high corrosive such as Amino plastic, thermo plastic PVC Plastic Moreover, it can stand for abrasive and wear, so this is good for plastic thermo setting mold. Thanks to its polishing ability, it can be used for Spectacular lens, camera lens, science experimental tube, syringe.Also, good for any cutting task like knife, cutting tool, kitchen utensil, spring, seal valve or machine part for mining/wood industry. Ruler and Slider calipers
