What Is O1 Tool Steel Grade
Tool steels are a class of metal alloys specifically designed for applications requiring hardness, wear resistance, and strength. Among these, O1 tool steel stands out for its versatility and performance. This article delves into the characteristics of O1 tool steel, discussing its composition, properties, and typical uses, with a special focus on the Yongxiang brand.
What Is O1 Tool Steel Grade?
O1 tool steel is a common type of cold-work tool steel characterized by its high wear resistance and ability to maintain sharp edges. It is composed primarily of carbon, with additional alloying elements such as chromium, manganese, and tungsten. The specific composition of O1 can vary slightly depending on the standard it adheres to, such as GB 9CrWMn in China, DIN 1.2510 in Germany, JIS SKS3 in Japan, and ASTM 2140 in the United States.
Properties of Yongxiang O1 Tool Steel
Yongxiang, a reputable manufacturer of tool steels, produces O1 tool steel that meets international standards, ensuring consistent quality and performance. The following are key properties of Yongxiang
O1 tool steel:
Hardness: O1 tool steel can be heat-treated to achieve a hardness of 60-66 HRC, making it ideal for applications requiring a sharp edge and resistance to abrasion.
