S235JR is a common designation for mild steel plates in Europe, and it represents a low carbon structural steel grade. This steel grade is widely used in various industries due to its versatility, affordability, and ease of fabrication.
Key features and applications of S235JR mild steel plates include:
- Low Carbon Content: S235JR contains a relatively low carbon content, typically around 0.17-0.20%. This low carbon content makes it easy to weld, form, and machine, making it suitable for a wide range of manufacturing and construction processes.
- Structural Use: S235JR is primarily used in structural applications, such as in the construction of buildings, bridges, and industrial machinery. Its good structural integrity and moderate strength make it a valuable choice for these applications.
- Weldability: It has excellent weldability, allowing for the fabrication of welded structures and components with ease. This makes it a preferred material for constructing steel structures and frames.
- Versatility: S235JR mild steel plates are versatile and can be used for various purposes, including making pipes, automotive components, and general engineering parts.
- Cost-Effective: Due to its widespread availability and relatively low cost, S235JR is an economical choice for many projects where high strength is not a critical requirement.
- Conformance to Standards: S235JR typically conforms to European standards (EN 10025) and is produced with consistent quality to meet the requirements of various industries.
- Surface Finish Options: Depending on the application, S235JR plates can have different surface finishes, such as hot-rolled, cold-rolled, or coated to enhance corrosion resistance.
In conclusion, S235JR mild steel plates are a versatile and cost-effective option for a wide range of structural and industrial applications. Their ease of fabrication, weldability, and compliance with industry standards make them a popular choice for engineers and manufacturers seeking an economical yet reliable material for various projects.

Frequently Asked QuestionsÂ
S235JR is a specific grade of mild steel defined under EN 10025. While it sits within the mild steel category, it has controlled chemical and mechanical properties that make it more predictable than generic or ungraded mild steel.
S235JR has a minimum yield strength of 235 MPa. This level of strength makes it suitable for lighter structural work and many general fabrication tasks.
Yes. S235JR can be cut using a variety of methods including plasma cutting, oxy fuel cutting, sawing and laser cutting. Its low carbon content ensures smooth cutting with minimal risk of edge cracking.
S235JR is well suited to cold forming because of its good ductility. It can be rolled, folded, swaged or bent into shape without requiring heating for most processes.
No. S235JR is generally used in its supplied condition and does not need heat treatment for standard applications. Heat treatment may alter its mechanical properties, so it is typically only done for specific engineering requirements.
It can perform well in applications with light or moderate vibration. For components exposed to continuous or heavy vibration, a higher strength structural grade may offer better long term performance.
Yes. S235JR is a mild steel containing iron, which means it is magnetic. This is useful in applications that require magnetic clamping or handling.
The density of S235JR plate is typically around 7.85 grams per cubic centimetre. This figure helps with calculating weight for transport, lifting or design planning.
Yes. For indoor, dry environments S235JR usually performs well without additional surface protection. For outdoor or humid environments, a coating or galvanising process is recommended.
Yes. While mild steel does not polish in the same way as stainless steel, it can be ground, smoothed and polished for a cleaner or more decorative finish. Additional surface protection is recommended after polishing to prevent rust.
S235JR is sometimes used for brackets, panels, fixtures and vehicle repair work. For safety critical components or parts exposed to high stress, a stronger grade may be more appropriate.
Because S235JR must conform to EN 10025, its chemical composition and mechanical properties are controlled. This ensures consistency from reputable suppliers. Choosing a stockholder with strong quality control helps guarantee this consistency.
Yes. S235JR is commonly used for light to medium duty brackets, supports and frames. It provides enough strength for general structural tasks while remaining easy to fabricate.
Yes. S235JR machines and drills easily using standard tooling. Cutting fluids can help achieve cleaner holes and prolong tool life, especially when working with thicker plates.
S235JR offers adequate impact resistance for normal structural use. For environments where impact loads are severe or frequent, a stronger grade like S355JR may be more appropriate.
Yes. Because it is a low carbon steel, S235JR tends to remain stable during cutting, forming and welding. It does not distort as easily as higher carbon steels.
Yes. S235JR takes paint well. Proper surface preparation such as degreasing and priming will help ensure a long lasting finish.
