14307 X2CrNi19-11 304L S30403 A193 B8 A320 B8
The ASTM specification A193 grade B8 or A320 grade B8 defines the technical characteristics of stainless steel hardware suitable for application in pressure vessels and in the presence of high or low temperature (service temperatures -196°C to 800°C); this type of hardware is widely used in the chemical plants oil and energy sectors.
ASME SA 193 B8 SA 320 B 8 specifications are reminiscent of ASTM A193 B8 A320 B8 specifications.
