What is S235JR material?
Steel grade S235JR is a popular general construction and machine steel that is made in accordance with the EN 10025-2 standard. Classification: Non-alloy structural steel. Products: Semi-finished products, long products and sheet hot-rolled products, wire rod and forgings.
What is S235JR steel equivalent to?
ASTM A36: ASTM A36 is an American standard carbon structural steel specification, which is often used in structural applications. It is closest to S235JR in terms of chemical composition.
What does the JR stand for in S235JR?
S235JR: The letter "S" stands for "Structural," indicating that the steel is a construction steel. The number "235" represents the minimum yield strength, i.e., 235 MPa (megapascals). The symbol "JR" refers to the toughness and impact resistance of the steel.
What is the yield strength of S 235 Jr?
Grade S235JR has a minimum yield strength of 235 MPa. The impact energy at a room temperature of 20°C is at least 27 joules. Steels of grade S235JR are suitable for low-stressed parts in steel and mechanical engineering.
Is S235JR a mild steel?
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.
What is S235JR steel material?
S235JR is a low-carbon, non-alloy structural steel defined by the EN 10025-2 standard. The "S" stands for "structural," meaning it is intended for use in load-bearing parts of buildings, machinery, or infrastructure.
What is the difference between S235JR and S355JR?
Yield Strength: S235JR has a nominal yield strength of 235 MPa, while S355JR offers a higher yield strength of 355 MPa. This 50% increase in yield strength makes S355JR capable of withstanding greater loads, making it more suitable for high-stress structural applications.
