Applications of AISI Q235C Carbon Steel Plate Sheet Hot Rolled Q345R & Q355R ASTM & BS Standard for Cutting & Welding

AISI Q235C carbon steel plate is common hot rolled material. Q345R and Q355R grades are also widely used. These plates offer good strength. They are suitable for many industrial jobs. Cutting these plates is straightforward. Plasma cutting works well. Oxy-fuel cutting is another option. Laser cutting gives clean edges. Welding these steels is reliable. Q235C, Q345R, and Q355R weld easily with common methods. Stick welding (SMAW) is fine. MIG/MAG welding (GMAW) is efficient. Submerged arc welding (SAW) handles thicker sections. Proper preheat might be needed for thicker Q345R or Q355R plates. This prevents cracking. Post-weld heat treatment is sometimes required for stress relief. Follow the standard guidelines. These plates meet ASTM and BS standards. This ensures quality and consistency. ASTM A36/A36M covers structural carbon steel. ASTM A573/A573M provides higher toughness. BS EN 10025 defines European structural steels. These standards guarantee the material properties. You know the steel will perform. Applications are diverse. Construction uses these plates for building frames. Bridges need strong, weldable steel. Q345R and Q355R are common here. Pressure vessel manufacturing uses Q345R specifically. Boilers and storage tanks rely on it. Machinery bases need durable plate. Q235C is often chosen. Shipbuilding uses these grades for hulls and decks. Transportation equipment uses them for trailers and chassis. Mining equipment faces heavy wear. These plates hold up. Fabrication shops use them daily. They are versatile and cost-effective. The hot rolled process gives a good surface for coating or painting. Dimensional tolerances are suitable for fabrication. Availability is usually good. Select the right grade for your project’s strength needs. Q235C offers basic strength. Q345R provides higher yield strength. Q355R offers similar strength to Q345R under the newer EN standard. Consider the required impact toughness. Check the specific standard for details. Cutting and welding success depends on correct procedures. Always refer to the material certification.

5 FAQs of AISI Q235C Carbon Steel Plate Sheet Hot Rolled Q345R & Q355R ASTM & BS Standard for Cutting & Welding

Here are 5 common questions about AISI Q235C, Q345R, and Q355R Hot Rolled Carbon Steel Plates:

What’s the main difference between Q235C, Q345R, and Q355R plates? Q235C is general structural steel. It offers good strength for basic uses. Q345R and Q355R are pressure vessel steels. They handle higher pressure and temperatures. Q355R often replaces Q345R in newer standards. Both Q345R and Q355R have stricter quality checks than Q235C.

Which standards apply to these plates? These plates follow specific international rules. Q235C typically meets Chinese GB/T 3274. Q345R meets Chinese GB 713. Q355R meets newer GB/T 713 or EN 10028 standards. They also correspond to common ASTM specs like A36 or A516. BS standards like BS EN 10025 are relevant too. Always check the exact standard needed for your job.

Can I cut these steel plates easily? Yes, cutting is standard. Methods include flame cutting, plasma cutting, and laser cutting. Q235C cuts most easily. Q345R and Q355R need slightly more care. Preheating might be necessary before cutting thicker sections. This prevents cracking. Follow standard cutting practices for carbon steel.

What about welding Q345R and Q355R plates? Welding is possible but needs preparation. Use suitable low-hydrogen welding rods or wires. Clean the weld area very well first. Remove rust, oil, and moisture. Preheating is often required for Q345R and Q355R. This depends on thickness and conditions. Control the heat input during welding. Follow the welding procedure specification exactly. Post-weld heat treatment is sometimes needed.

Do these plates resist rust well? These are carbon steels. They rust when exposed to air and moisture. Q235C has no special corrosion protection. Q345R and Q355R offer slightly better performance under pressure. They still need protection for long-term outdoor use. Apply paint, coatings, or galvanizing. Consider the environment. Use stainless steel for severe corrosion cases.
