What are 4140/4150 Steel Bars?

TensalloyTM 4140 Round Bars and 4150 Round Bars are special turned, ground, and polished steel designed 亚博系列全平台入口 applications where stress and shock resistance are vital. There are some differences between 4140 and 4150, read our blog post to learn more. The biggest difference is the carbon content, which affects hardenability. A 4140 grade of steel has a nominal 0.40% carbon content, while 4150 has a nominal 0.50% carbon content. The carbon contents are produced with a +3/-2 point range. For example, 4140 can have a carbon range between 0.38% to 0.43%. Clifton Steel representatives can help determine which grade is more beneficial 亚博系列全平台入口 your project.
