ASTM A572 Grade 60
ASTM A572 Grade 60 steel Product Introduction
The ASTM A572/A572M standard was first introduced in 1964, and has since become one of the most widely used standards for the production of steel products. This steel has been used in many applications across the globe in a variety of industries. It was designed to provide a high-strength, low-alloy material for use in bridges, buildings, and other structural applications.
ASTM A572 grade 60 Steel Product Details
The ASTM A572/A572M standard specifies the chemical composition of the steel, including carbon, manganese, phosphorus, sulphur, silicon, chromium, copper, nickel, molybdenum, and other trace elements. The specific chemical composition of the steel will depend on the grade chosen.
ASTM A572 Grade 60 Type 2 ASTM A572/A572M is an alloy of iron and carbon and other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances. The ASTM A572 Grade 60 Type 2 ASTM A572/A572M chemical composition determined by ladle analysis shall comply with the specified values of the following table.

ASTM A572 Grade 60 Type 2 ASTM A572/A572M Mechanical Properties
One of the main advantages of ASTM A572 Grade 60 Type 2 ASTM A572/A572M steel is its strength. This steel has a relatively high yield strength and a relatively low weight-to-strength ratio. This makes it ideal for use in a variety of construction applications. In addition, ASTM A572 Grade 60 Type 2 ASTM A572/A572M steel is relatively easy to form and weld.
Introduction of mechanical properties ASTM A572 Grade 60 Type 2 ASTM A572/A572M:
Yield point(σs)When the stress of ASTM A572 Grade 60 Type 2 ASTM A572/A572M or specimen exceeds the elastic limit in tension, even if the stress does not increase, the ASTM A572 Grade 60 Type 2 ASTM A572/A572M or specimen will continue to undergo obvious plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is called yield point.
Tensile Strength(σb) : The maximum stress of ASTM A572 Grade 60 Type 2 ASTM A572/A572M during tension from the beginning to the time of fracture. It indicates the ability of ASTM A572 Grade 60 Type 2 ASTM A572/A572M to resist fracture.
Elongation(δs) : The percentage of the plastic elongation length to the original sample length is called elongation.
Yield-strength ratio(σs/σb) : The ratio of yield point (yield strength) to tensile strength of ASTM A572 Grade 60 Type 2 ASTM A572/A572M is called its yield strength ratio. The greater the yield-strength ratio, the higher the reliability of structural parts.
Hardness: Hardness is the ability of ASTM A572 Grade 60 Type 2 ASTM A572/A572M to resist hard objects pressing into its surface. The higher the hardness, the better the wear resistance.
