Trusted ASTM A615 Grade 60 Rebar for Global Projects

ASTM A615 Standard Introduction

ASTM A615 is a widely used specification for deformed carbon-steel reinforcing bars, covering Grade 40, Grade 60, and Grade 75. Although this page focuses on ASTM A615 Grade 60, all material properties—chemical limits, mechanical strength, and dimensional requirements—follow the ASTM A615 standard framework.
Understanding the overall ASTM A615 specification helps buyers evaluate strength class, weldability, and alternative grades before choosing the most suitable rebar for their project.

ASTM A615 Grade 60 Reinforcing Bar (Rebar) Description

ASTM A615 Grade 60 rebar is engineered to improve the tensile strength of concrete and ensure stable load-bearing capacity. With raised ribs along the surface, this Grade 60 reinforcing bar enhances the bond with concrete, helping to resist stress caused by temperature changes, shrinkage, and heavy loads. Offering a minimum yield strength of 60,000 psi (420 MPa), it is widely adopted in bridges, foundations, highways, and large-scale civil engineering works where strength and durability are critical.

Chemical Composition of ASTM A615 Grade 60

The chemical composition of ASTM A615 Grade 60 reinforcing steel ensures both strength and durability. Elements are carefully controlled to achieve the required mechanical properties:

Element	Maximum %
Carbon (C)	0.30–0.50 (varies with bar size)
Manganese (Mn)	0.60–1.50
Phosphorus (P)	≤ 0.050
Sulfur (S)	≤ 0.060

• Carbon content improves tensile strength but affects weldability.
• Manganese enhances toughness.
• Phosphorus and Sulfur are harmful impurities and must be strictly limited.

Note: ASTM A615 Grade 60 is designed for mechanical strength, not for weldability. This composition is not optimized for welding. For weldable rebar, ASTM A706 is recommended. Contact our team if you need A706.

Mechanical Properties of ASTM A615 Grade 60

ASTM A615 Grade 60 rebar provides superior yield strength and tensile strength compared with lower grades.

Property	Value
Yield Strength	≥ 420 MPa (60,000 psi)
Tensile Strength	≥ 620 MPa (90,000 psi)
Elongation	≥ 9% (varies by size)

This balance of yield strength, tensile strength, and ductility makes Grade 60 rebar ideal for modern reinforced concrete design.

Common Applications of ASTM A615 Grade 60

Due to its excellent strength-to-cost ratio, Grade 60 rebar is the most common choice for:

• Residential foundations and multi-story buildings
• Bridges and overpasses (general structural reinforcement)
• Industrial warehouses and factories
• Roads and highways
• General civil engineering projects
