Within the first 100 words, it is important to highlight that we supply ASTM A572 Grade 50 carbon H beams directly from the mill, ensuring quality control, reliable delivery, and competitive pricing.


All A572 Grade 50 H beams are produced strictly in accordance with ASTM standards and supplied with complete Mill Test Certificates.

 

What Are ASTM A572 Grade 50 Carbon H Beams?

 

ASTM A572 Grade 50 carbon H beams are high-strength low-alloy (HSLA) structural steel sections manufactured to meet specific mechanical properties rather than chemical composition alone. They offer a minimum yield strength of 50 ksi (345 MPa), significantly higher than ASTM A36 structural steel.

Thanks to their optimized H-shaped cross-section, A572 Grade 50 H beams provide excellent load-bearing capacity, bending resistance, and structural efficiency, making them ideal for long-span and heavy-load applications.

 

ASTM A572 Grade 50 Carbon H Beams Chemical Composition

 

The chemical composition of ASTM A572 Grade 50 carbon H beams is carefully controlled to balance strength, toughness, and weldability.

Chemical Composition (%)

Grade C Si Mn P S V Ni Co
A572 Grade 50 0.23 0.40 1.35 0.040 0.050 0.06 0.015 0.05

This composition ensures ASTM A572 Grade 50 H beams perform reliably in welded and bolted structural systems.

 

ASTM A572 Grade 50 Carbon H Beams Mechanical Properties

 

ASTM A572 Grade 50 carbon H beams are supplied to guaranteed mechanical properties suitable for demanding structural applications.

Mechanical Properties

Yield Strength (MPa) Tensile Strength (MPa) Elongation (%) in 200 mm Elongation (%) in 50 mm
345 450 18 21

These values give A572 Grade 50 H beams an excellent balance between strength, ductility, and structural safety.

Application

 

What is ASTM A572 GR 50 standard?

ASTM A572 GR 50 is a high strength low alloy steel. Grade 50 is difficult to form since it contains more alloying elements than plain steel but offers more strength per unit of weight. Owing to its high strength ASTM A572 Grade 50 Plates requires less material to satisfy strength requirements than plain carbon steel.

 

What is the difference between A36 and A572 Gr50?

A572 Gr50 has a higher minimum requirement, ensuring more consistent high-end performance. A36 is cheaper per pound, but A572 Gr50's strength may mean you need less material, potentially reducing overall project cost. Both are easily welded, but A36 is slightly more forgiving for general fabrication

 

What is the difference between 4140 and A572 grade 50 steel?

A572 is a hot-rolled carbon steel that is used where a high strength to weight ratio is desired. A grade such as AISI 4140 offers decent corrosion resistance due to higher chromium and molybdenum content and is commonly used in firearm parts, pressurized gas tubes, and structural tubing for roll cages

 

Can you weld A36 to A572?

Weldability of the two steels is the same. Welds on the two steels (A36 and A36/A572 Gr 50 dual grade) using identical electrodes nuxcs and weld- ing parameters produced acceptable, ~quivalent welded JOints.

 

What is the ultimate strength of A572 grade 50 steel?

ANSWER: ASTM 572 Grade 50 steel has an ultimate tensile strength of 450 MPa (metric) and 65,300 PSI (Imperial). It has a tensile yield strength of 345 MPa and 50,000 PSI.
