介绍 | Carpenter Stainless Type 303 Se is a free-machining 18-8 chrome-nickel steel. Selenium, added to an 18-8 stainless steel that is ordinarily tough and difficult to machine, makes it so freely machinable that it can readily be handled on automatic screw machines at about 75% of the speed of C1212. This steel has displayed nongalling properties that make disassembly of parts easy and help to avoid scratching or galling in moving parts. Carpenter Stainless Type 303 Se has somewhat better formability than Project 70® Stainless Type 303 and should be considered for applications which involve cold-forming operations. Carpenter Stainless Type 303 Se has been used for parts that are fabricated by machining, grinding and polishing; for example, all types of screw machine products, valves, valve trim, etc. It is not recommended for vessels containing gases or liquids under high pressure. |
