ASTM A686 Type W5 Introduce
ASTM A686 Type W5 is an iron-based chemical composition alloy steel developed to meet American Society for Testing and Materials requirements. It is a versatile steel that is available in a variety of forms and steels, and is widely used in the manufacturing of a variety of products, including bridges, automobiles, piping and other industrial products. It is composed primarily of iron, with a small amount of carbon, manganese, phosphorus and sulfur. The alloying elements of this steel are chromium, molybdenum, cobalt and vanadium, resulting in a durable steel that can be heat treated for a variety of purposes.This steel has excellent resistance to corrosion and wear, making it an ideal choice for a variety of applications. It is also resistant to fatigue, making it suitable for heavy loads and high stress levels.
Smelting temperature:1651°C - 1991°C
