FAQ

What are the ASTM equivalents for international steel grades like S275JR and S355J2?

Many international projects specify European (EN) standards. Common equivalents include:

• S235JR: Equivalent to ASTM A36
• S275JR: Equivalent to ASTM A572 Grade 42
• S355JR/J2: Equivalent to ASTM A572 Grade 50 

What is the equivalent of ASTM A572 Grade 50?

ASTM A572 Grade 50 is a high-strength, low-alloy (HSLA) structural steel. Its closest international equivalents are S355JR (European), Q355B (Chinese), and 43A (British Standard).

What are the primary mechanical properties of ASTM A572 Grade 50?

ASTM A572 Grade 50 is known for its minimum yield strength of 50,000 psi (345 MPa) and a minimum tensile strength of 65,000 psi (450 MPa). It offers excellent weldability and formability for structural applications.

What is "PVQ" steel, and what grades do you stock?

PVQ (Pressure Vessel Quality) steel is designed for use in pressure vessels, boilers, and heat exchangers where notch toughness is critical. We stock common PVQ grades such as ASTM A516 Grade 70 and SA 516 Grade 60/70.

How do I choose between SA 516 Grade 60 and Grade 70?

The choice usually depends on the required strength. SA 516 Grade 70 offers higher tensile strength (70-90 ksi) compared to Grade 60 (60-80 ksi), making it more common for higher-pressure applications, though Grade 60 offers slightly better ductility.

Does Universal Steel offer AR500 steel plate for sale?

Yes, we distribute AR500 (Abrasion Resistant) steel plate, which is through-hardened for high-wear applications like mining, material handling, and liners. We also stock AR400.

What is ASTM A588 steel, and when should it be used?

ASTM A588 is a high-strength, low-alloy weathering steel. It is used in bridges and buildings where exposure to the atmosphere is a factor, as it develops a protective rust-like patina that eliminates the need for painting.

What is the yield strength of ASTM A36 steel?

ASTM A36 has a minimum yield strength of 36,000 psi (250 MPa). It is one of the most common mild steels used in construction due to its versatility and cost-effectiveness.

Do you stock ASTM A514 (T-1) quenched and tempered steel?

Yes, Universal Steel supplies ASTM A514, a quenched and tempered alloy steel known for its high yield strength (100,000 psi) and excellent weldability, often used in heavy equipment and structural frames.

Where can I find a comprehensive steel grade comparison chart?

Universal Steel provides a detailed comparison chart that cross-references common ASTM, EN, and JIS standards. These charts help engineers and buyers identify suitable substitute materials based on yield and tensile strength. View our steel grade comparison chart here!

What steel plate processing services do you provide?

We offer a full suite of processing services, including oxy-fuel and plasma cutting, drilling, tapping, countersinking, and bevelling. This allows us to deliver near-net-shape parts directly to your production line. Learn more about our services.

Can you provide countersinking and drilling for thick steel plates?

Yes. Our processing facility is equipped with high-precision CNC equipment capable of drilling and countersinking heavy plates (such as A572 or AR500) to meet exact customer specifications.

What are the standard plate sizes and thicknesses available?

We stock a wide range of thicknesses, from 3/16" up to 24" or more, depending on the grade. Standard widths typically range from 72" to 120", with lengths up to 480". Custom sizes can be cut to order.

Where is Universal Steel America located?

We are headquartered in Houston, Texas, and serve customers across North America. Our Houston facility specializes in rapid processing and shipping of heavy carbon steel plates.

What quality certifications does the company hold?

Universal Steel is committed to the highest standards of quality. Our facilities and processes are designed to meet ISO 9001 standards. We are also ASME-certified and adhere to specific industry standards for pressure vessel materials and ABS for shipbuilding grades.
