TECHNICAL DATA SHEET - ASTM A579 Gr.52
MATERIAL CATEGORY: Ultra high strength 1520Mpa alloy steel
MATERIAL DELIVERY CONDITION: Quenched and tempered
MAIN FEATURES: A579 series VAC-ARC steel is a medium carbon, low alloy, ultra high strength 1000Mpa steel primarily designed for high strength structural applications
A579 series steel is produced by the consumable electrode vacuum arc remelting process to provide optimum cleanliness and preferred ingot structure, which in turn provide optimum transverse mechanical properties.

MAIN FEATURES AND MELTING PROCESS
The steels shall be manufactured by melting process or VIM + ESR Melted and shall be finished by hot-worked forging.
Forgings may be furnished in one of the following conditions: stress relieving; annealing; solution treatment; solution treatment and ageing; normalizing; normalizing and tempering; or quenching and tempering.
Heat and product analyses shall be employed to assess the conformance of steels with required chemical compositions.
Forgings shall examined by tension and Charpy impact tests and conform to required mechanical properties such as yield strength, tensile strength, elongation, reduction of area, minimum room-temperature Charpy V-notch energy absorption, maximum annealed hardness, and section size capability. Nondestructive tests, such as magnetic particle, liquid penetrant, and ultrasonic inspection procedures, shall also be performed.
TYPICAL APPLICATIONS
Power generation – turbine fasteners – boiler support rods
Process plant – fasteners
Mechanical gears, gear shaft, main axis, valve rod
Multidiameter shaft
Pressure vessel
PRODUCT PROFILE AND AVAILABLE FORMS
Round bar (Diameter): 0.50mm to 800mm
Square bar / Flat bar: 3mm to 800mm
Length: random length, fixed length or based on the customer's special requirement.
Steel strip: T0.20 ~ 3mm X W10 ~ 2000mm X Coil
Heavy/middle plate via hot rolled: T4 - 200mm X W1000- 2500mm X L1000-12000mm
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
