Level 304 is a model “18\8” stainless. It’s the most commonly used and most flexible stainless steel exists, although the availability of a considerable number of substitutes; and has excellent welding and forming features.
The even-handed austenite form of level 304 allows it to be strictly deep pulled without medium annealing. This implies that this steel level predominates in creating drawn stainless components such as saucepans, hollow-ware, and sinks. It’s usual to use particular “304DDQ” variants for these applications.
Level 304 can be easily crushed or roll-formed into a diversity of elements for applications in the architectural, transportation, and industrial fields. It also has excellent welding features. When welding thin parts, it does not require post-weld annealing.
Level 304L, the 304 low carbon version, does not need pre-weld annealing and is hence widely used in large gauge components (more than 6mm). With its more extensive carbon content, Level 304H has used applications at high temperatures. Also, the austenitic form provides outstanding toughness to these levels. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures, even in very down to cryonic temperatures.
