Production introduction

Type 304 is an austenitic stainless steel. It has good corrosion resistance in many environments and may be formed and welded with ease. It has excellent ambient and low temperature toughness properties.

CRS vs 304 Stainless Steel

The difference between CRS and 304 stainless steel is that CRS is a process and 304 is an alloy. Steel, hot or cold rolled, will rust and corrode. It is used in applications where that is not a consideration. Stainless steel is an alloy with chromium and nickel that prevents rust and corrosion. It is used where rust and corrosion will be a problem. It is possible to buy 304 cold rolled stainless steel.

HEAT TREATMENT

Type 300 series austenitic stainless steels cannot be hardened by heat treatment, in fact the only heat treat operation that is performed on them is that of annealing. If these grades are slow cooled from forging, particularly through the temperature range 1500/ 900ºF (815/480ºC.) then grain-boundary chromium carbide precipitation will occur with a resulting very significant loss of corrosion resistance. As such annealing at around 1950ºF (1065ºC) followed by a water quench is a necessary part of the production process for type 304 forgings.


MACHINABILITY

Type 304 machines to give tough, stringy chips. Chip breakers are recommended and since the alloy has a rapid work hardening rate, positive feeds are recommended.


WELDABILITY

Type 304 may be welded by shielded fusion and resistance welding operations. Austenitic stainless steel welds do not harden on cooling, hence the welds will show good toughness.


Packing

Standard exported packing by wooden pallets or iron steel as photos. Eye to Sky and Eye to Sides package are both acceptable.
