Unleash the Power of Heat-Treatable Excellence - 1215 Steel

1215 Steel

1215 steel is a re-sulfurized and re-phosphorized free machining steel grade. It is useful in automatic screw machine operations and has replaced Bessemer B1113 due to its improved machining capabilities. This grade is ideal for applications that require excellent free-machining features and a smooth, bright finish.

Carbon as its primary alloying element also contains chromium, aluminum, molybdenum, and copper, contributing to its mechanical properties. It is often rolled into rods or drawn into wire for specific applications. Afterward, the steel goes through straightening, cut to length, and subjected to screw machine operations. 

Uses of 1215 Steel 

Notable applications for 1215 steel include hydraulic hose fittings, studs, pins, couplings, bushings, and inserts. It exhibits good machinability, allowing for efficient machining, roll threading, nibbling, and minor bending without cracking. However, it is not advisable for ordinary bending, forming, upsetting, or parts subjected to high fatigue stress.

Due to its high sulfur content, it has poor weldability. The recommended cutting speed for this grade is 225 feet per minute. Although it can respond to conventional heat treatments, it is the perfect choice as a case hardening steel.

1215 Carbon Steel Properties

1215 carbon steel is a low-alloy steel popular in manufacturing construction materials, automotive parts, and other products requiring high strength and corrosion resistance. The properties of this steel are from the heat treatment process, which the manufacturer specifies. Heat treatment can be performed using dry or wet methods, and different alloying elements can also impact the material’s properties. 

Critical properties of this carbon steel include:

  • Tensile strength: 5500 psi (29 MPa)
  • Yield strength: 4100 psi (21 MPa)
  • Ultimate tensile strength: 42000 psi (204 MPa) to 45000 psi (232 MPa)

These properties make this steel a high-strength, low-alloy steel suitable for various applications, particularly in structural components such as beams, columns, and girders.

Carbon Steel Heat Treating

Carbon steel is a common type of heat-treatable steel in industrial applications, making this steel heat-treating a common practice. It typically contains 0.25% to 1.75% carbon and 0.2% to 1% chromium.

You can achieve desired properties such as corrosion resistance, hardness, toughness, wear resistance, and good formability with low-load distortion through carbon steel heat treatment. This type of high-carbon steel is frequently utilized in the construction industry. It comes in various grades and can undergo heat treatment to enhance its properties.

Heat treating involves heating the metal to temperatures around 1,000 degrees Fahrenheit for an extended period, typically an hour or more. This treatment improves the steel’s mechanical properties and enhances its corrosion resistance.
