Stainless Steel 303 Round Bars – Bright & Black
EN 1.4305 / AISI 303 / SS2346 / UNS S30300 / X8CrNiS18-9
SS 303 Round Bars / 1.4305 / AISI 303 / SS2346 by using you get corrosion resistant free-machining stainless steel excellent for machining. It has good corrosion resistance and is often used for details within construction, building and processindustry.
The Stainless Steel 303 Grade (also called AISI 303, EN 1.4305 and SS2346) is a free-machining austenitic stainless steel with excellent machinability. It is suitable for massproduction of details requireing good resistance to atmospheric corrosion and good resistance to many organic and inorganic chemicals. It shall not be used in marine environment or coastal environments. It is non-magnetic but may become slightly magnetic after cold working and welding.
SS303 is one of the most widely used stainless steel grade. This grade is written as 1.4305 or X8CrNiS18-9 according to EN norm and it is written as UNS S30300 according to UNS norm. 1.4305 stainless steel has one of the best machinability in austenitic stainless steel grades. 1.4305 material is really close to 304 grade stainless steel and the main differences is the sulfur content of 303. Sulfur increases the machinability and 303 is one of the easiest grade to machine. But on the other hand, sulfur decreases the corrosion resistance a lot. The price of 303 grade is generally a bit higher than 304 grade stainless steel.
The SS 303 grade has a really good machinability. 303 grade stainless steel is not a very easy stainless steel grade to produce because of its sulfur and carbon content. These both elements cause easy crack formation and good quality of product is necessary to prevent cracks.

Machining of SS 303 Round Bars :
The steel grade 303 / 1.4305 contains sulphur which make it excellent for machining. The steel is not weldable due to the sulphur content and hot forming is difficult. It can be hardened by cold working.
