Understanding Mild Steel Grades: Which One Is Right for You?

As reported by The Piping Mart in their article, “What Are the Different Grades of Mild Steel?”, mild steel is a widely used material in construction, manufacturing, and automotive applications due to its affordability, strength, and versatility. This iron alloy, containing 0.2-0.3% carbon, is available in different grades, each offering unique mechanical properties suited for specific uses.
The most common mild steel grades include:
A36 – Affordable and easy to fabricate, widely used in structural applications like bridges and buildings.
S275JR – Offers higher strength than A36, making it ideal for bridge construction and projects exposed to harsh weather.
S355JR – Known for superior strength and corrosion resistance, often used in crane booms and heavy-load applications.
Q195 – A cost-effective option with good formability, making it suitable for stamped and deep-drawn parts like automotive components.
Q235B – Combines excellent weldability with durability, frequently used in bridge construction and complex shape forming.
Choosing the right mild steel grade depends on strength requirements, environmental exposure, and budget considerations. Whether for infrastructure, automotive manufacturing, or industrial projects, mild steel remains a versatile and reliable material.
