Product Description

4J58 overview
4J58 is an alloy with a certain expansion coefficient in the temperature range from room temperature to 600 °C. The expansion coefficient is basically the same as that of steel and cast iron at ambient temperature, and has good processing performance. It has good dimensional stability in long-term use and has certain corrosion resistance.

4J58 heat treatment system The expansion coefficient performance test sample specified in the standard is heated to 900°C ± 20°C in hydrogen or vacuum, kept for 1 hour, and cooled to below 200°C at a speed of no more than 5°C/min.
4J58 Melting and Casting Process After melting in non-vacuum induction furnace and electric arc furnace, electroslag remelting is carried out.

4J58 Application Overview and Special Requirements This alloy has stable properties and is mainly used to make precision line rulers (standard rulers) that transmit standard lengths at room temperature (20°C), and to make engraved rulers fixed on the body of a jig boring machine. Special attention should be paid to the content of carbon and other impurities during production and acceptance, because they are one of the causes of dimensional instability. In addition, the internal stress caused by the subsequent process should be minimized, and the production cycle should be appropriately lengthened for natural aging.
