What is ASTM A269?
A269 specification for seamless and welded Austenitic stainless steel tubing for general service. This specification covers grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and low- or high-temperature service.
What is a specification ASTM?
ASTM standards are formal, technical requirements that establish quality specifications for a wide range of materials, products, systems, and services; they serve as the basis for manufacturing, procurement, and regulatory activities worldwide. ASTM stands for American Society for Testing and Materials.
What is ASTM grade?
ASTM steel grades are those that meet the exacting standards for specific grades of steel developed by the American Society for Testing and Materials. The standards include mechanical properties and steel chemistries and specify the testing methods to be used.
Is standard for SS material?
The most common grade of austenitic stainless steel is 304 (1.4301). Globally, 304 accounts for more than 50% of stainless steel consumed. A common name for 304 stainless is 18/8. This name refers to the average composition, 18% chromium and 8% nickel.
What type of specifications did the ASTM first develop?
One of the first standard specifications in the history of the organization, “Structural Steel for Bridges,” was approved by the committee and submitted to all members for a final ballot vote at the annual meeting in 1901.
What material is ASTM?
steel
The most widely used standard specifications for steel products in the United States are those published by ASTM (American Society for Testing and Materials). ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products.
Can stainless steel rust?
Stainless steel is armed with built-in corrosion resistance but it can and will rust in certain conditions—although not as quickly or severely as conventional steels. Stainless steels corrode when exposed to damaging chemicals, saline, grease, moisture, or heat for prolonged periods of time.
What are the different types of ASTM standards?
ASTM stands for the American Society for Testing and Materials and has created six types of standards that relate to manufacturing processes such as testing, materials classification and operation. The six types are test method, specification, classification, practice, guide and terminology standards.
What are ASTM standards used for?
ASTM standards are used and accepted worldwide and cover areas such as metals, paints, plastics, textiles, petroleum, construction, energy, the environment, consumer products, medical services, devices and electronics, advanced materials and much more.
What are the ASTM A269 stainless steel tube grades?
ASTM A269 stainless steel tube main grades are: TP304/TP304L, TP316/TP316L, TP321, etc. This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low or high-temperature service.
What are the working pressures of ASTM A269?
Allowable working pressures are calculated from an S value of 20 000 psi (137.8 MPa) for ASTM A269 tubing at –20 to100°F (–28 to 37°C). Max. Length, м ANSON can supply ASTM A269 steel tube from stock or from reputed steel mills.
Which is the ASTM standard for stainless steel spring wire?
ASTM International Standard A313 is the standard specification for stainless steel spring wire. The specification covers austenitic, austenitic-ferritic, and age-hardenable stainless steel round spring wire intended especially for the manufacture of springs.
What are the ASTM standards for stainless steel tubing?
The specification covers grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and low or high temperature service. A269 compliance requires that all material must be furnished in the heat-treated annealed condition and that the steel must conform to chemical composition requirements.
