What is 3Cr13 Stainless Steel?
3Cr13 (also known as 30Cr13) belongs to the martensitic stainless steel series. Its carbon content and chromium composition are both higher than those of 1Cr13 / 2Cr13, featuring enhanced hardness and hardenability, while achieving moderate corrosion resistance through heat treatment. It has a good polishing effect and moderate wear resistance, making it suitable for component applications that require structural strength, surface precision, and oxidation resistance.
