HOT ROLLED STEEL COIL & SHEET PRODUCT LIST

ASTM A-1011 CS and DS

This specification covers commercial quality and drawing quality hot rolled carbon steel. Commercial Steel (CS) comes in four different Types (A, B, C, and D) and Drawing Steel (DS) comes in two different types (A and B). This material is intended for parts that may need to be bent, formed, drawn, punched, or welded. Commercial Steel comes in various carbon ranges with carbon maximums of 0.08%, 0.10%, and 0.15%. Drawing Steel is aluminum killed and is available with a minimum carbon level (0.02% – Type B). Applications for this material include agricultural implements, automotive equipment, barrels, drums, and general fabrication. This material is capable of being bent at room temperature in any direction through 180° flat on itself without cracking on the outside of the bent portion. The surface has a normal mill oxide finish. For improved flatness and improved processing performance, this material may be provided in the temper passed, stretcher leveled, or the pickled and oiled condition. Special surface finishes are also available for applications requiring a more uniform surface for painting.

ASTM A-1011 SS

This part of the specification covers structural quality hot rolled sheets. A-1011 SS is used in structural applications where specified strengths are required. Applications for these grades include agricultural implements, automotive equipment, utility bodies, tanks, construction equipment, and trailers. This material can be formed, punched, machined, and welded using acceptable shop practices. The surface has a normal mill oxide finish. For improved flatness and improved processing performance, this material may be provided in the temper passed, stretcher leveled, or the pickled and oiled condition. Grades included with the SS designation are 30, 33, 36 (Type 1), 36 (Type 2), 40, 45, 50, 55, 60, 70, and 80.

ASTM A-36

Intermediate tensile strength carbon steel for use in riveted, bolted or welded construction of bridges and buildings; and for general structural use. A-36 is one of the most widely used carbon steels for construction purposes. It is weldable, formable, and machinable. The minimum yield point is 36,000 psi and the tensile strength is 58,000-80,000 psi.

HIGH STRENGTH LOW ALLOY (HSLA)

ASTM A-606 – Type 4

This specification covers HSLA sheet with improved corrosion resistance. Type 4 has four times the atmospheric corrosion resistance of structural carbon steel. This sheet product is used in all types of structural applications from truck trailers frames to building components. It is weldable, formable, punchable, and machinable using the proper techniques. This product is often used in the unpainted condition as the surface will develop a weathered orange-brown oxide that is resistant to corrosion. ASTM A-606 Type 4 has a yield point of 50,000 psi minimum and a tensile strength of 70,000 psi minimum. Some of the trade names associated with this grade are Corten A, Mayari R, and Hi-Steel.

ASTM A-1011 HSLAS and HSLAS-F

This part of the specification covers high strength grades, and high strength grades with improved formability used where greater specified strength levels are required. The high strength grades are columbium-vanadium steels used in applications such as transmission towers, truck trailers, automotive parts and agricultural implements. This material can be formed, punched, machined, and welded using acceptable shop practices. For improved formability the HSLAS-F grades are available. The surface has a normal mill oxide finish. For improved flatness and improved processing performance, this material may be provided in the temper passed, stretcher leveled, or the pickled and oiled condition. Grades included in the HSLAS designation are 45 (Class 1 & 2), 50 (Class 1 & 2), 55 (Class 1 & 2), 60 (Class 1 & 2), 65 (Class 1 & 2), and 70 (Class 1 & 2). Grades included in HSLAS-F designation are 50, 60, 70, and 80.

CSA G40.21

G40.21 is a comprehensive CSA (Canadian) specification for Structural Quality Steel to meet a wide range of specific chemical and mechanical properties. There are eight different types of steel produced under this specification.

  • Type G     – General Construction Steel
  • Type W    – Weldable Steel
  • Type WT  – Weldable Notch Tough Steel
  • Type R     – Atmospheric Corrosion Resistant Steel
  • Type A     – Atmospheric  Corrosion Resistant Weldable Steel
  • Type AT   – Atmospheric Corrosion Resistant Weldable Notch Tough Steel
  • Type Q    – Quenched and Tempered Low Allow Steel Plate
  • Type QT   -Quenched and Tempered Low Alloy Notch Tough Steel Plate

Within these categories, there is a range of strength levels:
