If you're seeking a high-strength steel plate that delivers exceptional yield strength alongside solid weldability and formability, ASTM A514 GR C quenched and tempered steel plate stands out for challenging structural applications.

This alloy steel thrives in settings with substantial loads and moderate impacts, serving as a dependable choice for construction and heavy machinery. At Gangsteel, we focus on manufacturing and exporting premium ASTM A514 GR C plates, engineered with exacting standards to provide unwavering quality and performance tailored to your requirements.

Our A514 GR C plates are subjected to a meticulous quenching and tempering procedure: elevated to high heat, swiftly cooled to lock in hardness, and then tempered to refine toughness. This yields a robust yet fabricable material, perfect for welding into intricate assemblies while preserving structural soundness.

Drawing on extensive industry experience, Gangsteel guarantees that each plate undergoes thorough quality assessments, empowering your initiatives to withstand demanding conditions effectively.

 

What is ASTM A514 GR C Steel Plate?

ASTM A514 GR C represents a quenched and tempered alloy steel plate optimized for high-yield-strength in welded constructions. Within the A514 lineup, Grade C strikes an effective equilibrium, incorporating alloys such as chromium, molybdenum, and vanadium to amplify wear and fatigue resistance.

Suited for thicknesses reaching 6 inches, this grade upholds superior mechanical attributes under duress. Gangsteel manufactures A514 GR C plates that are adaptable for various fabrication needs, seamlessly fitting into designs for equipment like cranes, supports, or robust machinery.

 

ASTM A514 GR C Specification

The ASTM A514 standard defines protocols for high-strength, quenched and tempered alloy steel plates destined for structural welding. Grade C targets plates up to 6 inches, adjusting yield strength by thickness to enhance toughness.

At Gangsteel, our plates adhere completely to ASTM A514/A514M, encompassing required heat treatments and evaluations. We offer supplementary features like Charpy impact testing to surpass your project demands.

Mechanical Properties

ASTM A514 GR C exhibits formidable mechanical traits suited for structural resilience, with metrics adapting to plate thickness for ideal equilibrium. Essential elements encompass elevated yield strength (deformation resistance), tensile strength (load endurance), elongation (ductility aiding shaping without fracture), Brinell hardness (abrasion and wear fortitude), and low-temperature impact toughness (Charpy V-notch assessment, assuring functionality in cooler climates to -20°F or below via add-ons).

Gangsteel's plates are primed for scenarios demanding anti-fatigue and shock endurance. Elongation uses a 2-inch gauge, hardness ensures exterior longevity, and Charpy metrics (supplemental min 20 ft-lb at -20°F) affirm cold resilience.
