Steel Machining Material

John Prosock Machine, Inc., a CNC machine shop in PA, has years of experience in steel and stainless steel precision CNC machining. Generally, steel is malleable, strong, and versatile enough to be used in various end product or system applications; however, different grades demonstrate different machinability characteristics. John Prosock Machine can recommend the best steel based on your job requirements. There are essentially two types of steel, carbon and alloy. Listed below are some examples of the carbon and alloy steels we can machine and the possible uses of each.

Stainless Steel
Of the 150 plus grades of stainless steel that exist, 15 are most common. This alloy can be machined into sheet, plate, bar, wire, or tubing form for equipment ranging from cookware, to hardware, to surgical devices, to general appliances, and to industrial and architectural end part applications. Stainless steel is suitable in many natural and man-made environments due to its high resistance to oxidation and corrosion. Relative low cost, little maintenance, and luster make stainless steel ideal in many commercial applications as well.

316 Stainless Steel
316 Stainless is similar to 304 stainless steel, but includes molybdenum and an increased level of nickel. The addition of molybdenum makes 316 Stainless resistant to pitting and crevice corrosion. Even at high temperatures, 316 Stainless maintains its strength and creep, or deformation, resistance. Mechanical and corrosion properties withstand even under sub-zero temperatures. 316 Stainless has applications in many industry sectors from tanks and storages vessels, to equipment for chemicals, food, pharmaceutical, and petroleum.

Cold Rolled Steel
Cold rolled steel is processed while in a cold state. Hot chemically sanitized coil is rolled and then cooled. Cold rolling reduces the thickness of the steel and alters the mechanical properties. When this type of steel comes in contact with water in the air rust often forms. To prevent damage, cold rolled steel is covered with a thin layer of oil. Improved finish characteristics and close dimensions tolerances make cold rolled steel perfect for product where critical requirements, high quality, and consistency are important.

1018 Steel
1018 Steel is one of the most common grades of steel currently available. 1018 Steel is valued because it can be easily formed, machined, welded, and fabricated. Its chips are continuous and rigid which result in a fine finish. 1018 Steel is often utilized in high volume screw machine part applications commonly found in shafts, spindles, pins, rods, and more.

12L14 Steel
12L14 Steel is resulfurized and rephosphorized screw machine stock with the addition of lead content. This type of steel has good ductility and finish characteristics, which make it suitable for parts involving bending, crimping, or riveting such as in bushings, inserts, couplings, and hose fittings. 12L14 Steel is a form of carbon steel, a combination of carbon and iron, and has become an ideal precision machining material.
