ASTM A131 Steel, grade EH36 Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: ASTM A131/A131M Structural Steel for Ships, Grade EH36** --- #### **1. Product Overview** ASTM A131 Grade EH36 is a **high-strength, low-temperature service** steel plate designed for shipbuilding applications requiring superior toughness at extremely low temperatures combined with high strength. The "E" indicates its impact testing temperature category (-40°C/-40°F), while "H36" signifies high strength with a specified minimum yield strength of 355 MPa (36 kgf/mm²). This grade offers an exceptional combination of high strength, excellent low-temperature toughness, and good weldability, making it particularly suitable for polar vessels, ice-class ships, and offshore structures operating in Arctic conditions. --- #### **2.
