ASTM A242 is a specification for low-alloy structural steel with improved atmospheric corrosion resistance and higher temperature resistance. Steel plates with a thickness of up to half an inch are normally covered by this specification. ASTM A242 is used primarily in the fabrication of
ASTM A242 can withstand sustained temperatures to 800F.
The corrosion resistance of A242 is superior to that of carbon steels such as A36 and A572-50 with or without copper addition. Unpainted, A242 is suitable for many applications when properly exposed to the atmosphere.
The ASTM A242 has two grades, Type 1 and Type 2, with Type 1 being the most commonly used. Typically hot rolled, it is suitable for cutting, forming, drilling, and machining, as well as grinding.
Alloy steel also has the best tensile strength, so they are used in the manufacture of plates that are used in a variety of types of construction, as well as other industrial applications.
ASTM 242 TYPE 2 PLATES have a number of properties that make them suitable for use in various industries. Plates that are manufactured have properties such as corrosion resistance, great ductility, durability, high tensile strength, and stability in high temperatures and working conditions.
Petrochemical, pharmaceuticals, oil and gas, pulp and paper, and various other industries are some of the industries that use these plates. In these industries, the plates are used in a variety of applications.
Generally, ASTM A242 is applicable to steel plates with a thickness of one-half inch. It is a high-strength, low-alloy structural steel specification with improved atmospheric corrosion resistance.
A242’s atmospheric corrosion resistance is significantly greater than that of carbon steels such as A36 and A572-50, with or without copper addition.
ASTM A242 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength.
ASTM A242 is a high-strength low-alloy structural steel specification with improved atmospheric corrosion resistance and higher temperature resistance. This specification is normally applicable to steel plates up to one-half inch in thickness. ASTM A242 is typically used in the fabrication of
- Industrial air pollution stacks
- Air Ducts off pollution control equipment
- Water tanks
The ASTM A242 standard can withstand sustained temperatures of 800 degrees Fahrenheit.
If properly exposed to the atmosphere, A242’s atmospheric corrosion resistance exceeds that of carbon steels such as A36 and A572-50 with or without copper addition.
The minimum yield strength of ASTM A242 is 50ksi, and the minimum tensile strength is 70ksi
Tolerances OF ASTM A242 :
Tolerances for Mill Plate:
Plate thicknesses of 3/8 inches to 3/4 inches are available with ASTM A6 Half-Standard Flatness tolerances. Contact us for specific mill flatness capabilities.
Tolerances for Temper Leveled Plate:
A242 plates are manufactured to ASTM A6 tolerances for thickness, width, and length. For temper-leveled plates, ASTM A6 Half-Standard Flatness tolerances or better are available. A material’s yield strength and the processing line determine its flatness capabilities.
Tolerances for Coils for Conversion To:
For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses less than 0.230 inches (exclusive), and A635 for thicknesses between 0.230 inches and 1.00 inch, inclusive. ASTM specifications A635 and A568, respectively, specify thickness tolerances in Table S1.1. ASTM specifications A568 and A635 specify width tolerances in Table 6 and Table 3, respectively. It is necessary to inquire about thickness tolerances for nominal gauge orders.
