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\u00b0C to 800\u00b0C); this type of hardware is widely used in the chemical plants oil and energy sectors.<\/p>\n

ASME SA 193 B8 SA 320 B8 specifications echo the technical specifications of ASTM A193<\/a> B8 A320 B8.<\/p>\n

This material is suitable for making components that reflect EN ISO 3506-1 and EN ISO 3506-2 standards in the different mechanical strength characteristics depending on the state of the finished part (A2-50 A2-70 A2-80).<\/p>\n
