SS 304 stainless steel flat along with SS 304 flat are part of the austenitic family of stainless steel and they are known to be used in varieties of stainless steel applications. As compared to other products, SS 304 flat is a relatively low-cost offering and used in many applications.
Properties
SS 304 grades have excellent low temperature properties and respond well to hardening by cold working. 304 stainless steel flat may be subject to becoming a bit magnetic when worked and are not treatable with heat. 304 stainless steel flat grades possess better welding properties and post weld annealing is not regularly needed to restore performance.
