ASTM A572 Grade 50
Download data sheet
The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for used in general construction and structural applications. ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. For applications where notch toughness is important, consult SSAB for specific Charpy V-notch toughness requirements. ASTM A572 grades are used in a wide variety of structural applications in many market segments.

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 transverse direction according to ASTM A6 requirements. The tensile propertyrequirements are tablulated below:
|Elongation in 2" 1)
|Elongation in 8" 1)
|ASTM A572 Grade 50||0.100 - 4.00||50||65||21||18|
Can be dual certified as A572 Grade 50/CSA G40.21 50W upon request.
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.
