ASTM A656 Gr100 Structural Steel Plate
High strength low alloy steel sheet Product Introduction
This ASTM A656/A656M was created to provide a specification for hot-rolled structural steel plates with improved formability, weldability, and notch toughness. These characteristics, along with improved atmospheric corrosion resistance, make the material suitable for use in many industrial applications. ASTM A656 Type 7 Grade 100 ASTM A656/A656M primarily consists of iron and carbon and is also available in various grades, depending on the desired application. Although designed mainly for welded construction in which high strength is necessary, ASTM A656 Type 7 Grade 100 ASTM A656/A656M can also be used in lighter Section shapes.

ASTM A656 Type 7 Grade 100 ASTM A656/A656M Mechanical Properties
The main mechanical properties are elasticity, plasticity, stiffness, aging sensitivity, strength, hardness, impact toughness, fatigue strength and fracture toughness.
Elasticity: Metal material deforms when it is subjected to external force. When the external force is removed, it can restore its original shape.
Plasticity: The ability of ASTM A656 Type 7 Grade 100 ASTM A656/A656M to produce permanent deformation without causing damage under external forces.
Stiffness: The ability of ASTM A656 Type 7 Grade 100 ASTM A656/A656M to resist elastic deformation under stress.
Strength: The ability of ASTM A656 Type 7 Grade 100 ASTM A656/A656M to resist deformation and fracture under external forces.
Hardness: The ability of ASTM A656 Type 7 Grade 100 ASTM A656/A656M to resist the pressure of a harder object into it.
Impact toughness: The ability of ASTM A656 Type 7 Grade 100 ASTM A656/A656M to resist fracture under impact loading.
Fatigue strength: The maximum stress that does not cause fracture when ASTM A656 Type 7 Grade 100 ASTM A656/A656M is subjected to numerous repeated or alternating loads.
Fracture toughness: a performance index used to reflect ASTM A656 Type 7 Grade 100 ASTM A656/A656M is ability to resist crack instability and expansion
