ASTM A656 Grade 50
Download data sheet
The ASTM A656 specification is the Standard Specification for Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate with Improved Formability for plates in applications where increased strength-to-weight ratios are required. ASTM A656 includes five grades differentiated by minimum specified yield strengths of Grade 50, Grade 60, Grade 70, Grade 80 and Grade 100. Typical applications include construction equipment, crane booms, mobile man lifts, agricultural equipment, transport trailers, heavy vehicle frames and chassis, and rail cars.
|A656 Grade 50||Mill Plate||0.188 - 2.00||72 - 120||120 - 1020|
|A656 Grade 50||Temper Leveled Plate||0.100 - 0.625||48 - 96||72 - 720|
|—||Coil for Conversion To||0.188 - 0.625||60 - 96||—|
Temper Leveled Plate: SSAB's Cut-To-Length facilities use the temper leveled coil (TLC) process to produce temper leveled plate products. For additional information concerning our temper leveling process, please refer to our SSAB Americas: North American Cut-to-Length Operations brochure located under the Downloads section of our Commercial Steels Overview page.
Coil for Conversion To: Coils are excluded from qualification to this specification until they are processed into a finished plate product and all required processing, inspections, and testing are performed. Coils For Conversion To product will be certified to chemistry only. Coils will be subject to availability, so please inquire. Please inquire for coil dimensions outside the noted range. Slitting capabilities are determined by strength levels and thicknesses, so please inquire all slit coil opportunities.
Mill Plate: Please inquire for plate dimensions outside the noted range.
Tensile testing is performed in the tranverse direction. Tensile property requirements are tabulated below:
|Elongation in 2" 1)
|Elongation in 8" 1)
|A656 Grade 50||0.100 - 2.00||50||60||23||20|
1) For plates wider than 24 in., the elongation requirement is reduced two percentage points. Additional elongation requirement adjustments are allowed per the Tension Tests section of Specification ASTM A6.
