How about ASTM A572 grade 50 charpy impact

ASTM A572 grade 50 plate belongs to high strength low alloy steel, and it is suitable for application where there is need for more strength per unit of weight. That means less of ASTM A572 grade 50 plate is needed to fulfill given strength requirements than is necessary with common carbon steel materials. When mention A572 grade 50 steel, a lot of users also concern about ASTM A572 grade 50 charpy impact.

For ASTM A572 grade 50 charpy impact, ASTM A572 grade 50 plate absorbs energy more than 105J, satisfying the code requirement of 27J at 0°C in the Charpy impact tests. However, the welding heat increases the size of coarse grain and hardness in the heat affected zone (HAZ), reducing the Charpy value to 14.9 J.

ASTM A572 grade 50 plate contains more alloying elements than carbon steel materials, and it has increased resistance to atmospheric corrosion. Welcome to consult questions about ASTM A572 grade 50 plate, such as ASTM A572 grade 50 charpy impact.
