Frequently Asked Questions about HRS Steel S235JR

What is HRS Steel S235JR?

HRS Steel S235JR is a hot rolled non-alloy structural steel grade specified in EN 10025-2. It is widely used for structural and engineering applications due to its excellent weldability, machinability and cost-effective performance.

What does the "JR" designation mean?

The "JR" classification indicates that the steel achieves a minimum Charpy impact value of 27 Joules at +20°C, ensuring reliable toughness under standard operating conditions.

Is S235JR suitable for laser cutting?

Yes. HRS Steel S235JR is highly suitable for laser cutting. It produces clean, accurate cuts with excellent edge quality, making it ideal for precision-manufactured components.

Can S235JR be milled?

Yes. S235JR has good machinability and is well suited for milling operations. It can be accurately machined to produce finished components with tight tolerances.

Is S235JR easy to weld?

Yes. One of the key advantages of S235JR is its excellent weldability. It can be welded using conventional welding processes without requiring special procedures in most applications.

Can S235JR be galvanized?

Yes. S235JR is commonly hot-dip galvanized or coated with paint or powder coating to improve corrosion resistance for outdoor and industrial environments.

What is the difference between S235JR and S355MC?

S235JR is a general-purpose structural steel designed for standard engineering and fabrication work. S355MC is a high-strength thermo-mechanically rolled steel with significantly higher yield strength, making it better suited for lightweight structures, vehicle chassis and demanding load-bearing applications.
