SAE 1035 carbon steel

Introduction

We manufacture forging ingots, billets, and blooms in carbon steel specifically for SAE 1035, designed for low to medium strength engineering applications where good toughness, machinability, and weldability are required.

SAE 1035 is a medium-low carbon, unalloyed steel with a carbon content around 0.35%. It offers a good balance of ductility and strength, making it suitable for general fabrication, machining, and moderate load-bearing components.

This grade is commonly used in automotive, agricultural, and light engineering applications.

Chemical composition

Element Content (%) Function / effect
Carbon (c) 0.32 – 0.39 Provides moderate strength and toughness
Manganese (mn) 0.60 – 0.90 Improves toughness and hardenability
Phosphorus (p) 0.040 max Controlled to prevent brittleness
Sulphur (s) 0.050 max Improves machinability when controlled
Silicon (si) 0.15 – 0.35 Acts as deoxidizer and improves strength
Chromium (cr) Nil Not intentionally added
Nickel (ni) Nil Not present
Molybdenum (mo) Nil Not present
Other elements No significant alloying additions

Mechanical properties (typical – normalized / annealed condition)

  • Tensile strength: 460 – 620 MPa
  • Yield strength: 280 – 370 MPa
  • Elongation: 20 – 25 %
