ASTM A516 Gr65 pressure vessel steel A516 Grade 65 boiler plate

A516 Gr65 Boiler and pressure vessel steel Description

A516 Gr65 Steel belongs to the American standard boiler and pressure vessel steel plate. A516 Grade 65 follows the ASTM ASME technical standard, where 65 represents 65Ksi (Ksi represents mechanical strength unit). A516Gr65 pressure vessel steel has high strength, high toughness, wear resistance, fatigue resistance, impact resistance, weldability and cold forming performance, and is commonly used in the petrochemical container manufacturing industry.

Characteristics of A516 Grade 65 boiler steel

Strength: A516 Gr65 has high strength, mainly due to its chemical composition and heat treatment process. After appropriate heat treatment, this type of steel can achieve excellent mechanical properties and withstand various high-strength working environments.
Toughness: Although A516 Gr65 has high strength, it has not lost its toughness due to this. In the manufacturing process of pressure vessels, toughness is a crucial factor, as steel with insufficient toughness is prone to cracking when subjected to impact or vibration. The toughness of A516 Gr65 allows it to withstand high loads while resisting various impacts and vibrations.
Wear resistance: The wear resistance of A516 Gr65 is also very good, which allows it to maintain good working performance for a long time in friction and wear environments.
Fatigue resistance: Under repeated loads, A516 Gr65 can still maintain good fatigue resistance, thereby extending the service life of the equipment.
Impact resistance: A516 Gr65 has strong impact resistance, making it less prone to cracking or rupture even when subjected to large impact loads.

A516 Gr65 boiler and pressure vessel steel plate is widely used in various industrial fields. In the petrochemical container manufacturing industry, A516 Gr65 is used to manufacture pressure vessels, expansion joints, reactors, heat exchangers, petrochemical equipment, etc. In the field of petroleum machinery, it is used for manufacturing heads, boilers, power plant equipment, reaction kettles, etc. In addition, A516 Gr65 is widely used in the manufacturing of spherical tanks, nitrogen tanks, gas cylinders, liquefied gas tanks, etc.

When the thickness of A516 Gr65 steel plate is above 40mm, it is delivered in the normalized state by default. This is because in the normalized state, the grain size of the steel is finer and more uniform, and the comprehensive mechanical properties of the material are significantly improved, which is crucial for ensuring the safety and stability of the equipment.

ASTM A516 Gr65 pressure vessel steel plate is a high-quality boiler pressure vessel steel that combines high strength, good toughness, wear resistance, fatigue resistance, impact resistance, weldability, and excellent cold forming performance. It is an ideal material choice for various industrial fields. Whether in the petrochemical, petroleum, or power industries, the A516 Gr65 can meet various complex and demanding application requirements with its outstanding performance.
