11L41 Steel

The high sulfur content found within 11L41 carbon bar stock aids in the machinability of this heat treatable steel as it machines even better than the regular 11L41 steel round bar.

11L41 Carbon Round Bar Stock

11L41 carbon round bar stock is a type of carbon steel that contains carbon as the primary alloying element that has small quantities of molybdenum, chromium, aluminum, copper, and nickel. The chemical composition of 11L41 carbon bar stock consists of Iron, manganese, carbon, sulfur, and phosphorus with a density of 7.85g/cm3 this is the perfect steel that contains thermal conductivity of about 49.8W/mk in metric. 

The high sulfur content found within 11L41 carbon bar stock aids in the machinability of this heat treatable steel as it machines even better than the regular 1141.  Due to its free machining properties, this grade of carbon steel is usually used in high output machining and more often than not used in a cold drawn form.

With excellent toughness, high fatigue strength, and outstanding machinability, 11l41 steel has indeed become a staple for most industries in the Midwest.  

The 11l41 steel bar is a type of structural steel that is widely used in the construction industry. It has a high yield strength, which makes it resistant to buckling and distortion. 11l41 steel has been used for decades and is the most widely used form of steel. It is a versatile material that can be found in many facilities and industries.

The 11l41 steel is widely used in the construction industry because of its high yield strength, resistance to buckling, and distortion. It has a high yield strength because it has an elongation at a break of about 1%. 11l41 steel bar is typically made from iron, carbon, and alloying elements, such as chromium, nickel, manganese, cobalt, copper, and molybdenum. It can be forged into various shapes to suit different purposes.

For the automotive industry, 11l41 is used in the creation of engine gears, bolts and nuts, and crankshafts while for the oil and gas industry, It is utilized in the creation of spindles, couplings, and other mechanical parts.  

Whatever industry you are from, rest assured that Advance Grinding Services can provide you with a 11l41 round bar stock for all your specific industry applications.
