DIN 1.2316 / X38CrMo16 Plastic Mould steel
Description
1.2316 steel, also known as X38CrMo16, is a high-quality stainless tool steel designed for plastic molds requiring excellent corrosion resistance and high surface finish. With a high chromium content and added molybdenum, 1.2316 offers superior resistance to wear, humidity, and corrosive plastic materials like PVC. It provides good polishability, toughness, and dimensional stability after heat treatment. This makes it ideal for molds used in medical, optical, and food packaging industries, where hygiene and high surface quality are critical. 1.2316 is often chosen for producing transparent or chemically aggressive plastic products, ensuring long mold life and consistent performance under demanding conditions.
