Stainless Steel

304 Stainless Steel Spring  SAE  304  stainless steel Spring also known as  A2 stainless steel  (not the same as A2  tool steel ) or commercially as  18/10 or   18/8 stainless steel , European norm 1.4301, is the most common stainless steel. The steel contains both  chromium  (between 18-20%) and  nickel  (between 8-10.5%) [1]  metals as the main non- iron  constituents. It is an  austenitic stainless steel . It is less electrically andthermally  conductive  than  carbon steel  and is essentially non-magnetic.  It has a higher  corrosion  resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. [2] The composition was developed by  W. H. Hatfield  at  Firth-Vickers  in 1924 and was marketed under the trade name "Staybrite 18/8". [3] . The Japanese equivalent grade...

316 Stainless Steel Washers 316 Stainless Steel Washers Washer (hardware) 316 Stainless Steel Washers is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a  threaded fastener , such as a  screw  or  nut . Other uses are as a spacer, spring ( belleville washer , wave washer), wear pad,  preload  indicating device, locking device, and to reduce vibration ( rubber washer ). Washers often have an outer  diameter  (OD) about twice their inner diameter (ID), but this can vary quite widely. Washers are usually  metal  or  plastic . High-quality  bolted joints  require hardened steel washers to prevent the loss of pre-load due to  Brinelling after the  torque  is applied. Rubber  or  fiber   gaskets  used in  taps  (or faucets, or valves) to stop the flow of water are sometimes referred t...
