ASTM MATERIALSASTM

ASTM (American Society for Testing and Materials) A group of scientists and engineers formed the American Society for Testing and Materials in 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 A320ASTM

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. Inside ASTM A320 several grades are covered, including both ferritic and austenitic steels designated L7, B8, etc. Selection will depend on design, service conditions, mechanical properties, and lowtemperature characteristics The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Like the ASTM A193 specification, unless otherwise specified, the 8UN thread series is specified on fastener larger than 1 in diameter.

MATERIALS- HEX NUTS ASTM A194 ASTM A194 pecification covers a variety of carbon, alloy, and martensitic and austenitic stainless steel nuts. These nuts are intended for high-pressure or high-temperature service, or both. Bars from which the nuts are made shall be hot-wrought. According to ASTM A194 the material may be further processed by centerless grinding or by cold drawing. Austenitic stainless steel may be solution annealed or annealed and strain-hardened. Each alloy shall conform to the chemical composition requirements prescribed. Hardness tests, proof of load tests, and cone proof load tests shall be made to all nuts to meet the requirements specified. ASTM A194 stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Within the text, the SI units are shown in brackets. ASTM A194 covers size range through 4 in. and metric M6 through M100 nominal. It also covers austenitic stainless steel nuts in the size range in. and M6 nominal and above. Unless otherwise specified, the American National Standard Heavy Hex Series (ANSI B 18.2.2) shall be used. Nuts up to and including 1 inch nominal size shall be UNC Series Class2B fit. Nuts over 1 inch nominal size shall be either UNC Series Class 2B fit or 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the marketplace.

ASTM A320 L7STUDBOLT 'S MATERIALS

MATERIALS-STUDBOLTS ASTM A320 L7 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. Inside ASTM A320 several grades are covered, including both ferritic and austenitic steels designated L7, B8, etc. Selection will depend on design, service conditions, mechanical properties, and lowtemperature characteristics The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Like the ASTM A193 specification, unless otherwise specified, the 8UN thread series is specified on fastener larger than 1 in diameter. ASTM A320, Grade L7 - This grade is intended for low-temperature service down to minus 150F and has a minimum Charpy impact value of 15 ft-lb at this temperature. Sizes 2-1/2 in. and under.
