ASTM SA-105

ASTM SA-105 Grade Introduction:

Carbon Steel ASTM SA105 Forged Fittings created in different evaluations of steel and its alloys. Our Forged Pipe Fittings are fabricated with the most extreme accuracy, guaranteeing that our scope of items agrees to universal quality parameters. our Carbon Steel Fittings are generally figured for sturdiness, erosion resistance and dimensional.

ASTM SA-105 Grade Application:

This ASTM specification covers carbon steel forgings for piping applications such as flanges and fittings (45°eblow, 90°eblow, tee, coupling, etc

Forging Properties:

ASTM SA105 carbon steel can be forged at temperatures in the range of 2200 to 1700 F followed by quenching and tempering or normalizing. The actual hot forging temperatures in the closed die forging process will be decided by a number of factors, such as the complexity of the forged part.The proper temperature of forging can only be checked at the beginning of forging, higher temperature will probably cause surface defects, such as mill scales, which will bring uneven surface. And lower temperature will be not conducive to the plastic deformation of C1045 carbon steel forged part.

Stress Relieving:

50℃ under the temperature of tempering
