Stainless steel application guidelines

201 High work-hardening rate low-nickel equivalent of type 301. Flatware, automobile wheel covers, trim. 

202 General-purpose low-nickel equivalent of type 302. Kitchen equipment, hub caps, milk handling. 

205 Lower work-hardening rate than type 202 used for spinning and special drawing operations. Nonmagnetic and cryogenic parts. 

301 High work-hardening rate used for structural applications where high strength plus high ductility are required. Railroad cars, trailer bodies, aircraft structural, fasteners, automobile wheel covers and trim, pole line hardware. 

302B More resistant to scale than type 302. Furnace parts, still liners, heating elements, aimealing covers, burner sections.

Common applications for hot water/steam within a winery are at the bottling line and for stainless steel tanks. Hot water can be employed to sanitize lines based on a guideline of >82°C/180°F for more than 20 min as measured at the most distant point in the line. When steam is used to sanitize tanks, the recommendation is to continue until condensate from valves reaches >82°C/180°F for 20 min. In both cases, the temperature should be monitored at the point most distant from the steam source (i.e., the end of the line, fill spouts, etc.). The practice of dismantling valves, racking arms, and other parts for immersion in containers of hot water may not yield an adequate time and temperature relationship necessary for sanitization.
