Characteristics
1.2083/420/4Cr13 is a kind of Martensite stainless steel, with good machincability and excellent corrosion resistance, polishability, and high strength and wear resistance after heat treatment. It is widely used for making plastic moulds and transparent plastic molds which require high load, wear resistance, and work under the action of corroding medium.
Applications
1.2083 is used for plastic moulds with high wear resistance and corrosion resistance requirement; transparent plastic moulds, such as PVC.
Delivery Time: 7-10 working days for steel in stock. 20-60 working days for direct production based on the quantity.
