Boiler quality plate materials ASTM A-516 Gr.55 N A 516 Gr. 55 steel plate

ASTM A-516 Gr.55 N (A 516 Gr.55) is a common boiler grade sheet material commonly used in the manufacture of pressure vessels, boilers, and other high-temperature equipment, with excellent heat resistance and mechanical properties.

1. Features: A-516 Gr.55 N steel plate has undergone normalizing treatment (N represents normalizing treatment), which enhances its mechanical properties and toughness, making it suitable for working under high temperature and high pressure.

2. Application areas: A 516 Gr.55 steel plate is widely used in the manufacturing of boilers and pressure vessels in industries such as chemical, petroleum, and power, ensuring stable operation of equipment under harsh conditions.

3. Chemical composition: Typical chemical compositions include carbon (C) up to 0.18%, sulfur (S) up to 0.035%, manganese (Mn) ranging from 0.55% to 0.98%, and other elements that meet the requirements of relevant standards.

4. Mechanical properties: A-516 Gr.55 N steel plate has good strength and heat resistance at high temperatures, suitable for applications in high-pressure and high-temperature environments.

Choosing steel plates that comply with ASTM A-516 Gr.55 N standards ensures excellent performance of equipment in high temperature and high pressure environments, and meets the strict requirements of industry for quality, safety, and reliability.
