Here are the top 10 questions about A36 steel and the answers:

What is A36 steel?

A36 is a low carbon steel alloy specified by ASTM international, widely used for structural applications like beams and steel buildings.

What are the chemical composition/properties of A36?

It contains up to 0.29% carbon, 1% manganese, 0.4% silicon, 0.4-0.8% for other elements like phosphorus, sulfur. Yield strength is 36,000 PSI.

What are the common sizes/shapes of A36 steel?

Wide flange beams, channels, angles, plates, bars, rounds in varying thicknesses and dimensions keeping the strength specifications.  Contact us today to discuss carbon steel for your project needs.

What are the welding methods for A36?

Shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW), gas tungsten arc welding (GTAW) are most commonly used to join A36 members.

What are the typical applications of A36 steel?

Structural beams, columns in buildings, bridges, pressure vessels, offshore oil rigs, mining machinery where adequate strength is needed for varying design loads.

Is A36 suitable for use at high/low temperatures?

It retains strength up to ~550°F but becomes weaker at cryogenic temperatures below 0°F. Special fabrication may be required.

How do I specify A36 in drawings/BOMs?

Simply mention 'A36 steel' or its ASTM specification A36/A36M. Additional info like dimension, heat number may be included as required.

What tests are conducted on A36 steel?

Tensile test, charpy impact test, hardness testing, macro etching, sulfur print tests to verify composition and mechanical properties meet standards.

Who are major A36 steel manufacturers?

Nucor, Liberty Steel USA, ArcelorMittal, EVRAZ, Gerdau, SSAB, Russel Metals, Olympic Steel are some top producers of rolled structural sections in North America.

Does A36 rust/require protective coatings?

It can rust if unprotected. Galvanizing or painting is generally adopted for outdoor structural applications of A36 steel for corrosion prevention.
