PRODEC® 304/304L       SPEC SHEET

PRODEC® (PRODuction EConomy), is a special quality of austenitic stainless steel. The uniformity and optimal machinability of PRODEC allows fabricators to machine at higher speeds and feeds, producing superior quality parts at the lowest total cost. It should be considered for automatic screw machines where extensive machining is required. PRODEC 304/304L is an improved version of standard 304/304L processed for improved machinability and outstanding uniformity. PRODEC 304/304L offers faster machining speeds, longer tool life, improved part quality and lower total cost of machined parts. PRODEC 304/304L is nonmagnetic in the annealed condition, but may become slightly magnetic as a result of cold working or welding.
Rolled Alloys Machining Quality (PRODEC) 304/304L bar can increase yields and extend tool life to reduce machining costs. PRODEC 304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, to many organic and inorganic chemicals, and to food and beverages. It has also been used in vacuum processing equipment and specialized instruments where high integrity is essential.
Although improvements in machinability in the past have been associated with reduced corrosion resistance, PRODEC 304/304L has been shown to have corrosion resistance within the range typically expected to 304/304L stainless steel. Because of its low carbon content, PRODEC 304/304L retains this
corrosion resistance in the as-welded condition.
It is common for PRODEC 304/304L to be dual certified as PRODEC 304L and PRODEC 304 when that material meets both the lower carbon limit of 304L
and the slightly higher strength of 304. PRODEC 304/304L is readily welded by full range of conventional welding procedures except oxyacetylene. AWS E308L/ER308L filler metal should be used with PRODEC 304/304L steel.
