The 304L stainless steel round bar is a widely used product. It is highly resistant to different types of corrosion and heat. This is due to the 18 percent chromium and 8 percent nickel that it has been alloyed with. It has resistance to intergranular corrosion and organic acids that are moderately aggressive. In some cases, 304L stainless steel has better corrosion resistance than 304 alloys. This metal is typically used in sufficiently corrosive environments and heat-affected zones that would typically corrode other metals. It has good oxidation resistance when serviced in temperatures up to 1600 degrees F and 1690 degrees F of continuous service. It’s also great at resisting carbide precipitation.
This metal has excellent weldability and formability. After welding thin pieces of this metal, it’s recommended to perform post-weld annealing. It’s important to ensure the preservation of corrosion resistance and prevention of cracking when welding together joints to austenitic steels such as this. When forging, it’s best to use heat uniformity up to 2100/2300 degrees F. After forging has been completed, air cooling can be used without worry about cracking. Temperatures below 1700 degrees F shouldn’t be used for forging 304L alloys.
Cold working can be used for tensile strengthening and hardening. Heat working won’t accomplish this. This metal is capable of deep drawing, which is why it’s used to fabricate sinks and hollow-ware. Since this is an austenitic metal, it doesn’t require intermediate annealing while being deep drawn. This metal hardens quickly. Full annealing or stress relief annealing should be done to reduce stresses that are caused by forming and spinning.
This product can be purchased in dimensions ranging between 0.125 and 6 inches and up to 144 inches long.
