ASTM A514 GR B Quenched and Tempered Steel Plate supplier

ASTM A514 GR B Quenched and Tempered Steel Plate

If you're searching for a reliable high-strength steel that can take on heavy-duty jobs without breaking a sweat, ASTM A514 GR B quenched and tempered steel plate is a top pick. This tough material is built for structural uses where you need serious strength and impact resistance. At Gangsteel, we produce and export premium ASTM A514 GR B plates that hit all the marks for quality and performance, meeting global standards every time.

Think of quenched and tempered steel like A514 GR B as steel that's been through a smart heat workout: heated up hot, cooled fast in water or oil (quenching), then gently reheated (tempering) to boost its toughness. This process makes it super strong, wear-resistant, and easy to weld or shape, perfect for big machines or builds that face rough conditions.

What is ASTM A514 GR B Steel Plate?

ASTM A514 GR B is a powerhouse alloy steel plate from the A514 series, all about delivering high yield strength in welded setups. It's quenched and tempered to balance brute force with flexibility, making it a favorite for projects needing lightweight yet sturdy parts.

This grade stands out for handling thicknesses from about 3/16 inch up to 6 inches, where it keeps its edge under pressure. Alloyed with bits of chromium, molybdenum, and vanadium, it fights off cracks and wear like a champ. Gangsteel crafts these plates with top-notch care, so you get consistent results for your builds.

ASTM A514 GR B Specification

The ASTM A514 spec lays out rules for high-strength, quenched and tempered alloy plates meant for welded bridges and heavy structures. For Grade B, it focuses on plates up to 6 inches thick, with yield strengths that drop a tad as they get thicker to stay tough.

Everything follows ASTM A514/A514M guidelines, covering chemistry, strength tests, and that key heat treatment. Plates come ready-to-use in quenched and tempered form, often with extra checks like ultrasonic testing. At Gangsteel, we stick to these specs to guarantee your A514 GR B plates are spot-on.

Supply Specifications

At Gangsteel, we offer flexible sizing for ASTM A514 GR B steel plates to match your project's needs. Whether you want standard stock or custom cuts, our production handles a wide range. Here's a quick look at our typical supply specs:

These dimensions make it easy to fit into cranes, frames, or any heavy setup. We can tweak them further—just let us know!

Chemical Composition

The secret sauce in ASTM A514 GR B steel plate is its precise mix of elements, tuned for max strength and weldability. It uses alloys like chromium for hardness and molybdenum for toughness, keeping things corrosion-resistant too.

The composition is controlled through ladle analysis (during melting) and product analysis (on the finished plate, allowing small tolerances per ASTM A6). Here's the breakdown in one table for easy comparison:

These values ensure tight quality control, with product analysis reflecting minor variations from processing.

Mechanical Properties

ASTM A514 GR B delivers outstanding mechanical performance, making it a go-to for applications demanding high load-bearing capacity and resilience. Its properties are influenced by plate thickness, with higher values for thinner sections to optimize strength without brittleness. Key metrics include yield strength (the point where permanent deformation starts), tensile strength (maximum stress before breaking), elongation (ductility measure, indicating how much it can stretch before failure), Brinell hardness (resistance to indentation, tied to wear resistance), and low-temperature impact toughness via Charpy V-notch testing (energy absorbed during fracture at cold temps, crucial for harsh environments).

The table below details these properties, based on ASTM A514 requirements. Elongation is measured in 2 inches (50 mm) gauge length. Hardness is typically 235-293 HBW for plates up to 6 inches. Charpy impact is supplemental (optional but often specified) at a minimum of 20 ft-lb (27 J) average for three specimens at -20°F (-29°C), ensuring toughness in cold conditions like outdoor structures or machinery.

This profile allows for lighter, more efficient designs while withstanding fatigue, abrasion, and sudden impacts. The elongation ensures good formability during welding or bending, hardness boosts longevity in abrasive settings, and the Charpy values confirm reliability in sub-zero temps.

Applications of A514 Grade B Steel Plate

ASTM A514 GR B steel plate powers up industries that can't afford weak links. It's a star in construction gear like crane arms and bulldozer blades, where it hauls heavy loads and shrugs off hits.

Mining ops love it for truck beds and loader buckets battling rocks and dirt. You'll spot it in farm tools, truck chassis, and haul trailers too. Bridges and building frames use it for welded strength that lasts. Gangsteel's shipped tons of GR B worldwide, backing tough projects everywhere.

Equivalent Grades (A514 vs EN 10025-6 S690QL vs JIS G3106 SM570)

ASTM A514 GR B lines up with global standards for similar high-toughness steels, giving you sourcing options across borders.

EN 10025-6 S690QL matches its yield punch for Euro builds, while JIS G3106 SM570 from Japan offers close weld ease for Asian projects. Throw in China's GB/T 16270 Q690D and Australia's AS/NZS 3678 Grade 450 for more fits.
