What things should I consider while buying an A709 50 plate?

  • Request material test certificates to verify the plate meets ASTM A709 Grade 50 specifications and the required mechanical properties.
  • Determine the specific purpose of the ASTM A709 gr50 plate and ensure it is suitable for your intended use.
  • Choose the appropriate size and thickness based on your project’s structural requirements and load-bearing capacity.
  • If the plate will be exposed to corrosive environments, go for ASTM A709 Grade 50 Type 2, which offers enhanced atmospheric corrosion resistance.
  • Go for a certified supplier who complies with relevant quality standards.
  • Clarify the expected delivery date and lead times to meet your project’s timeline.

What are the differences between A709 gr. 50 and 50w?

A709 Grade 50 contains more C and slightly higher Mn content. A709 Grade 50W has additional alloying elements.
ASTM A790-50 steel plate has no added corrosion resistant elements. Grade 50W can exhibit enhanced atmospheric corrosion resistance due to its alloying elements. It forms a protective rust like layer when exposed to weathering so it does not require additional surface coating.

What testing procedures are used to guarantee the quality of A709 gr50 plates?

  • Chemical Composition Analysis ensures the chemical composition meets the specified requirements.
  • Tensile Testing determines the tensile & yield strengths and elongation and ensures the plate meets the minimum specified values.
  • Charpy V-notch Impact Test evaluates the toughness and resistance to brittle fracture of the A790-50 steel plate, especially at low temperatures.
  • Ultrasonic Testing detects internal defects or discontinuities in the plate using high frequency sound waves.
  • Visual Inspection identifies any visible defects or irregularities.

The choice of the test will depend on your specific requirements. Contact Ridhi Siddhi Steel Corporation to get tested and certified ASTM A709-50 structural steel plate at competitive prices.
