Product Description

420 4Cr13 S136 1.2083 Special Stainless Steel Round Bar

Product Introduction
It is a stainless martensitic steel with a high hardenability, good polishing properties, excellent resistance to corrosion and hot oxidation.
Its applications are plastic moulds, particularly for acid aggressive plastics (e.g. acetate and PVC), or plastics containing abrasive fillers.
GB standard 4Cr13 die/tool 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.

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
