Founded on June 1981, Jinhwa has manufactured not only high manganese steel heat resistant steel, alloy steel used for cement industry, mines and dredger parts but also wear resistant steel which is high chromium cast iron product for 30 years. We took notice of the fact that mechanical properties of metals such as crash worthiness, wear resistance, heat resistance, etc. may be improved based on the method of heat treatment and our professional researchers and technicians who have worked in their own field over 30 years have made their best in technical development for the advanced heat treatment methods. Therefore, we are pleased to say that our product is suitable for it’s usage exactly, by the result of our scrutinized analysis on changeable factors of our customer’s working conditions. In addition, we have the keen concern on the points that optimized design and quality products manufactured on scientific process by us are directly link with your cost saving as well as working result.
