SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use. The steel groups are indicated below:
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. [1] A specification is often a type of technical standard . There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts.
A UNS number only defines a specific chemical composition, it does not provided full material specification. Requirements such as material properties (yield strength, ultimate strength, hardness, etc.), heat treatment, form (rolled, cast, forged, flanges, tubes, bars, etc.), purpose (high temperature, boilers and pressure vessels, etc.) and testing methods are all specified in the material or ...
Website. www.astm.org. ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. [2] For example, there may be a specification for a turbine blade for a jet engine that defines the exact material and performance requirements.
EN 1069: Water slides of 2 m height and more. EN 1078: Helmets for pedal cyclists and for users of skateboards and roller skates. EN 1090: Execution of steel structures and aluminium structures (3 parts) EN 1092: Flanges and their joints. Circular flanges for pipes, valves, fittings and accessories, PN designated.
Electrical properties. Volume resistivity (ρ) 32.5–39.2 nOhm·m. 6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [2]
