Description

Product Description

ASTM A350 is a specification for carbon and low-alloy steel forgings, intended primarily for use at moderate and high temperatures. It covers several grades of carbon and low-alloy steel forgings, including grades LF1, LF2, LF3, LF5, LF6, LF9, LF787, and LF802.

These forgings are typically used for pressure vessel applications, such as flanges, fittings, valves, and other components in the petroleum, chemical, and power generation industries. ASTM A350 forgings are designed to withstand high temperatures and pressures, and they exhibit excellent strength, toughness, and corrosion resistance.

The chemical composition and mechanical properties of the forgings are specified in the ASTM A350 standard. The forgings are made through a process of heating, shaping, and cooling, which involves the use of hammers, presses, or other forming equipment. The forgings are then heat treated to achieve the desired mechanical properties.

It is important to note that ASTM A350 forgings should be used only in accordance with their intended design and service conditions. Proper testing, inspection, and documentation procedures should be followed to ensure the quality and safety of the forgings.

Overall, ASTM A350 is a widely recognized specification for carbon and low-alloy steel forgings, providing guidelines and requirements for their manufacturing, mechanical properties, and application suitability.

Product Parameters

As specified by ASTM A350, after hot working and before reheating for heat treatment, the forging shall be allowed to cool substantially below the transformation range. Forgings of grades other than Grade LF787 shall be furnished in the normalized, or normalized and tempered, or quenched and tempered condition. All quenched forgings shall be then tempered at 1100 °F [590 °C], minimum, holding at temperature a minimum of 30 min/in. [30 min/25 mm] of maximum thickness, but in no case less than 30 min. Grade LF787 forgings shall be furnished in either the normalized-and-precipitation heat treated condition or in the quenched-and-precipitation heat treated condition.
