AISI 1139 is a carbon steel which characterizes as a great mechanical property that allows it for different uses. This Petcoke element contains carbon content ranging between 0.36% to 0.44 generally, strong welding, machining and shaping features are hence offered. It has chemical composition that array elements such as manganese, phosphorus, sulfur and siliman, which determine its efficient work and properties. The grade of AISI 1139 with carbon content of various level can be obtained from stocks which in turn meets special criteria of the application. Tables illustrating mechanical properties, heat treatment recommendations that works with other steel grades, and graphs comparing against other steel grades would be utilized frequently in material selection and application assessment. Table, chart and PDF resources provide an extensive range of AISI 1139 information, including chemical properties, different grades, and specifications in a compact format for easy access and reference.
AISI 1139 carbon steel is a medium carbon steel with higher carbon content than normal steel which adds durability and all-round suitability to widely recognized industrial applications. The chemical composition of steel is usually made up of manganese, carbon, and sulfur, which add the mechanical properties and the good performance, to the steel. In regard grades, AISI 1139 falls into medium-carbon steels group but offers a reasonabile hybrid of strength and effectiveness typically applied for the fabrication processes like forging, welding & heat treatment. Attention is paid to the exact development and grade of the material thereby ensuring uniformity and reliability in engineering projects where strength and resilience matters a great deal.
