ASTM (American Society for Testing and Materials)
A group of scientists and engineers formed the American Society for Testing and Materialsin 1898.
ASTM International (ASTM), is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services
ASTM predates other standards organizations such as (1901), DIN (1917) and AFNOR (1926), but differs from these in that it is not a national standards body.

ASTM A320 / A320M Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for Low-Temperature Service
MATERIALS-STUDBOLTS ASTM A320
ASTM A320 specification covers alloy steel bolting materials for pressure vessels, valves, flanges, and fittings for low-temperature service. Each alloy shall conform to the prescribed chemical composition requirements. The material, as represented by the tension specimens, shall conform to the requirements as to tensile properties such as tensile strength, yield strength, elongation, and hardness. The material shall meet the prescribed impact energy absorption requirements and the recommended test temperature. According to ASTM A320 mechanical tests shall be conducted on the material, namely: impact testing, tension testing, and hardness testing.

ASTM A182 / A182M Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service
MATERIALS-STUDBOLTS/HEX NUTS ASTM A182
ASTM A182 specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts for high-temperature service for use in pressure systems. Included are similar parts to specified dimensions or to dimensional standards, such as the ASME specifications that are referenced in Section Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in this specification. Selection will depend upon design and service requirements.
