The precision formwork steel is mostly medium-sized, high-carbon alloy steel. After quenching, some of the supercooled austenite is not transformed into martensite, and remains in the used state to become retained austenite, which affects the performance. If the precision mold frame is cooled below zero, it can promote the martensite transformation of the retained austenite.
When you use some precision mold bases, in addition to the high quality of the products, you need to be suitable for your own application, in order to show good application results. Compared with the general mold base, the precision mold base can be more suitable for everyone''s application, so that it can have the advantage of better application effect when applied.
