What is condition a 303 stainless steel?
303 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190.
What is the difference between 303 SS and 304 SS?
303 is a free-machining grade of 304 stainless steel that contains added sulfur or selenium. The addition of sulfur or selenium increases the machinability. While 303 stainless steel still has strong corrosion resistance, for an added boost, 304 stainless steel is recommended.
What is AISI 303 steel?
AISI 303 is an austenitic stainless steel, offering an excellent machinability and toughness, being the most readily machine-able of all austenitic grades of Stainless Steel. It’s corrosion resistance however, is weaken then that of type 304.
Can you harden 303 stainless?
Grade 303 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.
Is 303 stainless steel ferritic?
Similar to carbon steels, sulfur can be added to increase machinability; grade 303 is an example of this. It is very similar to grade 304 except that sulfur has been added to it for machining purposes. Grade 416 is example of a ferritic stainless steel with added sulfur.
Is 303 or 304 harder?
Mechanical properties slightly differ. Type 303 has somewhat higher tensile strength when compared to the Type 304, but has lower yield strength and elongation capacity.
Is AISI 303 magnetic?
Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel.
Is 303 ferrous?
The machineable nature of Grade 303 stainless steel is due to the presence of Sulphur in the steels composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness….Chemical Composition of Stainless Steels.
