What is ST35 Carbon Steel?
ST35 is a non-alloy structural carbon steel grade that offers moderate strength and high ductility. The grade name “ST” represents structural steel, while “35” refers to its minimum tensile strength of approximately 350 MPa.
Also identified as Carbon Steel 1.0308, ST35 steel is easy to weld, form, and machine, making it suitable for both light and medium-duty applications. This is why ST 35 Round Bars are widely chosen for shafts, pins, fasteners, brackets, and fabricated components.
Forms of Carbon Steel ST35 Bars We Supply
To meet varied industrial needs, we supply ST35 steel in multiple shapes:
- ST35 Round Bars – Used for shafts, pins, and machined components
- Carbon Steel ST35 Rods – Ideal for precision engineering
- Carbon ST35 Hex Bars – Commonly used for bolts and fasteners
- Carbon ST35 Square Bars – Used in frameworks and supports
- Carbon ST35 Rectangular Bars – Suitable for base plates and structures
- ST35 CS Flat Bars – Used in fabrication and reinforcement works
- ST35 Carbon Black Bars – Hot-rolled bars for heavy-duty use
ST35 vs EH 36 Hot-Rolled Steel Bars
While ST35 Carbon Steel Round Bars are ideal for general engineering, EH 36 Hot Rolled Steel Bars are designed for shipbuilding and offshore applications.
- EH 36 Carbon Steel HR Round Bars offer higher strength and impact resistance
- Used in marine structures and offshore platforms
- We also supply EH 36 Steel Bars as an EH 36 Steel Bars Supplier in India
