Product Description<\/div><\/div><\/div>\n\n\n\n


ASTM A320 Grade L7 Bolt<\/strong>, is a standard specifically developed for pressure vessels, valves, flanges and fasteners for operation at low temperatures (cryogenic). Made from alloy steel, these bolts and studs maintain their mechanical strength in extremely cold environments down to -101\u00b0C (-150\u00b0F). The main feature that distinguishes L7 quality from others is the Charpy V-Notch impact test, which is compulsory during the production process; this test proves that the material does not become brittle at temperatures well below freezing and proves its impact absorption capacity (toughness). It is commonly used in LNG plants, refrigeration systems and pipelines in arctic climates. ASTM A320 L7 studs are generally used for full compliance and safety. ASTM A 194 Grade 7<\/strong> used together with nuts.<\/p>\n\n\n\n
