introduction
Alloy Steel A514 in CNC Machining
A514 steel is a cost-effective, high-performance material known for its strength, weldability, and toughness, especially in low temperatures.
It's a low carbon, quenched, and tempered alloy steel meeting ASTM International standard A514, with a yield strength of 100,000 psi. A514 plate steels are a group of alloys with attractive advantages, including a minimum tensile strength of 100 ksi and at least 110 ksi ultimate strength. Plates of different thicknesses exhibit specified tensile strengths. A514 plates are weldable and tough at low temperatures. They are commonly used in building constructions.
It is also used in heavy equipment due to its high yield strength. Grades like B, S, and E are common, each with specific thickness limits. Despite differences in composition and thickness, all grades share similar properties. We can cut A514 using various methods and machining with conventional tools. Due to the high hardness of A514, post-machining treatments such as stress relieving may be required to reduce internal stresses and improve dimensional stability.

TECHNOLOGY OVERVIEW
Basic Knowledge of Alloy Steel A514
What is Alloy Steel A514?
Alloy Steel A514, also known as T-1 steel, is a high-strength, low-alloy steel plate. It belongs to the ASTM A514/A514M specification, which covers quenched and tempered alloy steel plates of structural quality in thicknesses of 6 inches (150 mm) and under intended primarily for use in welded bridges and other structures.
The A514 steel grade designations are categorized based on their minimum yield strength. The grades range from Grade A with a minimum yield strength of 100 ksi (690 MPa) to Grade F with a minimum yield strength of 100 ksi (690 MPa). The higher the grade, the higher the yield strength.

FAQ
Machining Alloy Steel A514 Buying FAQs
A514 and A36 are different types of steel commonly used in construction and heavy equipment welding. A36 is low-carbon steel with good strength and formability, while A514 is high-strength steel with a yield strength of around 100,000 PSI, depending on the grade.
Both ASTM A517 and A514 are high-strength quenched and tempered alloy steels, but they have different grades and applications. A514 is primarily used for structural purposes, while A517 is typically used in pressure vessel applications. Each grade has specific mechanical properties and heat treatment requirements.
A514 and A572 are different types of high-strength, low-alloy steels. A514 is a quenched and tempered alloy steel, primarily used for structural applications, while A572 is a standard specification for high-strength low-alloy structural steel with specified minimum yield strength. A514 is known for its high yield strength, making it suitable for heavy-duty applications.
The tempering temperature for A514 steel is typically in the range of 1,100 to 1,300°F (593 to 704°C). However, the specific tempering temperature may vary depending on the grade of A514 and the desired mechanical properties.
