Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel A514 Gr P alloy steel plate can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.
A514 Gr P alloy steel plate, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.
Our company will accept the product quality objection registration record, pass it to the A514 Gr P alloy steel plate production unit and relevant departments, and timely coordinate the supervision of product A514 Gr P alloy steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
