What is the composition of A514 grade F?
Product information of A514 grade F
ASTM A514 Grade F is a quenched and tempered alloy steel plate used in structural applications that require high yield strength combined with good formability and toughness. A514 Grade F has a minimum yield strength of 100 ksi and may be ordered with supplemental Charpy V-notch toughness test requirements.
Applications
Typical applications for A514 Grade F include transport trailers, construction equipment, crane booms, mobile aerial work platforms, agriculture equipment, heavy vehicle frames and chassis.
Alloy steel plate A514 Grade F,A514GrF contains more kinds alloy elements such as Nickel,Chromium,Molybdenum,Vanadium,Titanium,Zirconium,Copper and Boron when rolling. The chemical compostion of heat analysis shall be comply to the below table.As for the delivery condition,high strength steel plate ASTM A514 Grade F shall be under quenched and tempered.Tension test and Hardness test shall be done in the mill when rolling. All the test result values for structural steel plate A514GrF should write on the original mill test certificate.
Alloy steels are designated by AISI four-digit numbers. They are more responsive to heat and mechanical treatments than carbon steels. They comprise various types of steels having compositions which exceed the limitations of Va, Cr, Si, Ni, Mo, C and B in the carbon steels.

1. What is the typical impact toughness requirement for A514 Grade F?
A514 Grade F typically requires a minimum Charpy V-notch impact energy of 54 Joules (40 ft-lbs) at -40°C (-40°F), ensuring excellent fracture resistance in cold environments and dynamic loading applications.
2. How thick can A514 Grade F plates be ordered?
It is commonly produced in thicknesses up to 100 mm (4 inches) while maintaining full through-thickness properties, though some mills can supply thicker plates with adjusted mechanical guarantees.
3. What filler metals are recommended for welding A514 Grade F?
Welding requires matching high-strength, low-hydrogen electrodes such as E11018 or E12018 classifications, with strict adherence to preheat (300-400°F) and interpass temperature controls to prevent hydrogen cracking.
4. Does A514 Grade F require post-weld heat treatment (PWHT)?
Yes, PWHT is strongly recommended for most welded fabrications to relieve residual stresses and restore toughness in the heat-affected zone, particularly for thick sections and highly restrained joints.
5. Can A514 Grade F be flame-cut without special precautions?
Flame cutting requires preheating to 200-300°F before cutting to prevent hardening and micro-cracking along the cut edge, especially for thicknesses above 2 inches.
