Request Information
Hot Rolled Carbon Steel Plates are produced from basic oxygen process steel. The designations applied to this material are based upon the types of mills used to produce the plates and the resulting edge conditions. SHEARED PLATES have been rolled between horizontal rolls, with edges and ends later trimmed by shearing to obtain rectangular shape. In the heavier thicknesses (generally over 1 1/2"), the trimming is accomplished by flame cutting—hence the designation FLAME CUT PLATES.

Specifications

N/A Thickness Range Normally Stocked ASTM A 36 3/16"-16"
When material over 1 1/2" thick is used as bearing plates in structures other than bridges, ASTM A 36 applies.

Applications

N/A Storage tanks, storage bins, welded pipe, bridge construction, freight and passenger cars, barges, tankers, machinery construction, mining cars and equipment, bearing plates for buildings, and other structural applications and various parts obtained by flame cutting with our modem shape cutting facilities.

Mechanical Properties

N/A ASTM A 36
Tensile Strength - 58/80.000 psi
Yield Point - 36,000 Min. psi
Elongation in 8" - 18% Min.
a Subject to reduction for thidknesses under 5/16"

Machinability

N/A Hot Rolled Carbon Plates have a machinability rating of approximately 72%, based on 1212 as 100%, with average surface cutting speed of 120 feet per minute. When considerable machining or drilling is to be performed, we recommend the use of Free-Cutting Plates.

Weldability

N/A These plates are easily welded by all the welding processes and the resultant welds and joints are of extremely high quality. The grade of welding rod to be used depends on the thickness of section, design, service requirements, etc.
