2.What are the characteristics of ASTM A517/A517M?

High Strength:Designed for applications requiring exceptional yield and tensile strength, especially in welded pressure vessels subjected to high stress.
Weldability:Offers good weldability with appropriate preheating and post-weld heat treatment (PWHT) to prevent cracking.
Heat Treatment:Typically quenched and tempered (Q&T) to achieve required mechanical properties.
Impact Resistance:Provides excellent toughness and impact resistance, even at low temperatures (varies by grade, e.g., Grade E offers improved low-temperature toughness).
Grade Variations:Includes grades like Grade B, Grade E, Grade F, etc., each tailored for specific environments and stress conditions.
Thickness Range:Available in various thicknesses (typically up to 150 mm or more, depending on the grade and manufacturer).

3.What is the equivalent of ASTM A517/A517M?

The equivalent grades of the ASTM A537 Class 1 Carbon Steel Plates are the DIN 19Mn5 and SPV36 standards. All these plates are produced under the watchful eye of our experienced staff.
