What is AR450 Steel?
Tensalloy鈩� AR450 steel is a high-carbon steel alloy that has a surface hardness between 400-477 BHN.
Differences between AR400, AR450, and AR500 steel
While Tensalloy鈩� AR450 steel is similar to Tensalloy鈩� AR400 and Tensalloy鈩� AR500, there are some variances that make each unique. Differentiators include hardness levels, application uses, and cost. You can find hardness levels 亚博系列全平台入口 AR400, AR450, and AR500 on their respective pages. While Tensalloy鈩� AR400, Tensalloy鈩� AR450, and Tensalloy鈩� AR500 all offer excellent hardness, the 亚博系列全平台入口mability and brittleness of each vary. When looking 亚博系列全平台入口 steel that requires hardness with good 亚博系列全平台入口mability, Tensalloy鈩� AR400 and Tensalloy鈩� AR450 are the better options. If wear is a critical issue, Tensalloy鈩� AR500 is the appropriate choice based on the increased hardness and wear resistance.
Of course, cost is also a factor. Tensalloy鈩� AR400 is the most cost-effective option. While Tensalloy鈩� AR450 and Tensalloy鈩� AR500 have higher costs, they also achieve higher degrees of hardness.
